On the Historical Geography Examination of Senior One in Jiangxi Province

Chapter V: Geographical differences in China.

1, China has a vast territory, and the geographical environment in different regions is very different. According to the differences in (geographical) location, (natural) environment and (human) geographical features, China can be divided into (4) large geographical regions, namely (North) region, (South) region (Northwest) region and (Qinghai-Tibet) region.

2. The monsoon region generally includes the (north) region and the (south) region in the four geographical regions of China; Non-monsoon regions generally include the (Northwest) region and the (Qinghai-Tibet) region in China.

3. The dividing line between the southern region and the northern region generally passes through the Qinling Mountains and Huaihe River, which is basically consistent with the 1 month (0) degree isotherm and the (800) mm annual precipitation line.

4. Affected by the natural environment, there are also great differences in (mode of production), (living habits) and (cultural traditions) between the North and the South. Farmland in the north is mostly (dry land), mainly planted (wheat, soybean), cooked (once a year) or (three crops every two years). Traffic is mainly (land traffic). There are many paddy fields in the south, mainly planted (rice, rape, etc.). ), and ripening (two crops a year) or (three crops). Transportation mainly depends on water.

5. The topography of the northern region is mainly (plains and plateaus). Climate type (temperate monsoon climate). The southern region includes (the middle and lower reaches of the Yangtze River, the southern coast and the southwest); In humid (subtropical and tropical monsoon) climate, the topography is mostly staggered (plains, hills, basins and plateaus).

6. The northwest region includes the northern part of the province (Inner Mongolia Autonomous Region, most parts of Xinjiang Uygur Autonomous Region and Gansu). The climate is mainly temperate continental climate (arid and semi-arid). The terrain is mainly (plateau, basin). The eastern plateau is dominated by landforms (grasslands and deserts); There is a large area (desert) in the western basin, and only sporadic oases appear on the edge of the basin. There are few rivers in northwest China, most of which are inland rivers.

7. The Qinghai-Tibet region includes the western part of the province (Xizang Autonomous Region, Qinghai and Sichuan); The climate is dominated by (alpine climate); The terrain is mainly (plateau, mountain). With an average altitude of over (4,000) meters, it is known as the "roof of the world".

8. Northwest China and Qinghai-Tibet are the main pastoral areas in China, and the pasture and main livestock breeds have their own characteristics. Inner Mongolia (temperate grassland pasture); Xinjiang is mainly (mountain pasture); Mainly Qinghai and Tibet (alpine pasture). Hulunbeier grassland in Inner Mongolia (three hippos and three cows), Xinjiang (fine wool sheep), Qinghai-Tibet (yak), (Tibetan sheep) and Ningxia (Tan sheep) are all famous livestock breeds.

9. In the foothills of the northwest (Hetao area, Ningxia Plain, Hexi Corridor, Tianshan Mountain), people have developed (irrigated agriculture) by using meltwater (river water, mountain ice and snow); In the Qinghai-Tibet region (Yarlung Zangbo River basin), (Huangshui River basin) and other low-altitude areas, there is (valley) agriculture.

Chapter VI Understanding Provinces and Regions

1, Beijing is located in the north of the (North China) Plain, which is the center of the whole country (politics and culture) and also the center of international exchanges. It is the hub of China (road, railway and air traffic).

2. The pattern of the old city of Beijing was formed in the Yuan and Ming Dynasties. The buildings in the city are arranged like a chessboard, and the Forbidden City is located in the center of the city, which is the representative of the planning and construction of China's historical capitals.

The Hong Kong Special Administrative Region and the Macao Special Administrative Region are located on the east and west sides of the lower reaches of the Pearl River, of which (Hong Kong) is located on the east side and (Macao) is located on the west side.

Hong Kong consists of three parts (Hong Kong Island, Kowloon Peninsula and New Territories) and more than 200 surrounding islands. It is an international trade center, (transportation center, financial center), information service and (tourism) center.

5. Hong Kong has a small population, more (mountainous areas) and less (flat land), and the land resources available for urban development are limited. "Going to heaven"-building tall buildings and "going to sea"-reclaiming land from the sea have become two important ways for Hong Kong to expand its urban land use.

6. Macau is composed of (Macau Peninsula, Taipa Island and Coloane Island), and (gaming tourism) is an important pillar industry of Macao's economic development.

7. Taiwan Province Province includes (Taiwan Province Island) and many small islands nearby (Penghu Islands and Diaoyu Islands). Taiwan Province Island is the largest island in China. It borders the East China Sea of China in the north, the Pacific Ocean in the east, the South China Sea in the south and Fujian Province across the Taiwan Province Strait in the west. It is also a rich treasure island, with superior natural environment and abundant resources (forests, minerals and aquatic products), and is known as the "pearl of the southeast sea of the motherland".

8. Taiwan Province Island has a (subtropical and tropical) climate, which is warm and humid. The (plain) land in the west is fertile and rich in fruits (rice, sugarcane, tea and tropical and subtropical). The forest area is vast and has the reputation of "Asian Natural Botanical Garden". Cinnamomum camphora is the most famous tree species in Taiwan Province Province, and its camphor production ranks first in the world. In addition, Taiwan Province Island is also known as "the rice warehouse on the sea, the sweet island in the east, the hometown of fruits, the sea of forests and the southeast salt bank".

9. Since the 1960s, Taiwan Province Province has made use of its own advantages to focus on the development of (export processing) industries and formed an "import-processing-export" economy. The proportion of industrial products in export trade has steadily increased. Among them, the industry is mainly distributed in the (western) plain.

10, Xinjiang Uygur Autonomous Region, located in the border of China (northwest), is the largest province in China, and it is a multi-ethnic area with (Uygur) and (Han) as the main body. Known as (the hometown of singing and dancing, the hometown of melons and fruits). There are the largest desert (Taklimakan Desert), the hottest place (Turpan Basin) and the largest basin (Tarim Basin) in China.

1 1. Xinjiang mountains and basins are alternately distributed, with (Altai Mountain) in the north, (Tianshan Mountain) in the middle and (Kunlun Mountain) in the south. The majestic North Tianshan and South Tianshan are (Junggar) and (Tarim) basins respectively.

12, because it is far away from the ocean and surrounded by tall mountains, the airflow from the ocean is not easy to reach, so Xinjiang (precipitation) is scarce and the climate (drought). There are sporadic oases in the piedmont plain and some areas along the river at the edge of the basin. Their water sources mainly come from precipitation (mountain areas) and meltwater (ice and snow).

13, Xinjiang (oasis) is the most important agricultural production base, where summer (high temperature) and (light) are sufficient (large temperature difference between day and night), which is suitable for planting a variety of crops. People use the ancient water diversion project (karez) to develop characteristic (irrigation) agriculture. Wheat, corn and sorghum are the main crops here. Based on the unique light and heat conditions, (cotton, sugar beet and various fruits) have become the characteristic agricultural products of Xinjiang oasis.

14. The deserts in Tarim Basin are widely distributed and rich in oil and gas resources, of which natural gas accounts for 22% of the total land natural gas resources in China. With the gradual implementation of the national energy strategic decision of "stabilizing (east) and vigorously developing (west)", Xinjiang is expected to become an important industrial (oil and gas) base in China.

The implementation of 15 (West-to-East Gas Transmission Project) will promote the use of clean energy such as natural gas in cities and villages around Tarim Basin, and relieve the (environmental) pressure caused by firewood logging in surrounding areas. Drive local economic development.

Chapter VII Inland Areas of the Province

1. The Pearl River Delta is located in the southeast of Guangdong Province, at the lower reaches of the Pearl River, adjacent to Hong Kong and Macao, and across the sea from Southeast Asia. It is called the "South Gate" of China.

2. The special economic zones in the Pearl River Delta are Shenzhen and Zhuhai, and the coastal open city is Guangzhou.

3. The Pearl River Delta and Xishuangbanna are both tropical monsoon climates with high temperature and rainy weather, but the wind direction of summer monsoon is different.

4. The products of the Pearl River Delta are exported to Southeast Asia, Europe, Africa, America and Oceania through Hong Kong and Macao. At the end of the 20th century, it became the largest export base of electronic products and consumer goods in the world.

5. The Pearl River Delta is an export-oriented economy, and the basic mode of cooperation with Hong Kong and Macao is "store in front and factory in back".

In recent years, the focus of foreign investment has shifted from the Pearl River Delta to the Yangtze River Delta.

7. The development of processing and manufacturing industry in the Pearl River Delta has promoted the development of service industry and absorbed a large number of foreign countries.

The labor force has accelerated the pace of urbanization.

8. At present, China's urbanization level is less than 40%, which has a certain gap with 70% in developed countries.

Xishuangbanna is located at the southern foot of Hengduan Mountains in Yunnan Province, bordering Myanmar and Laos in the south, and the Lancang River flows through it.

10, Xishuangbanna is the best-preserved tropical rain forest in China except Hainan Province, with many kinds and layers of rain forest vegetation.

1 1. The main ethnic minority in Xishuangbanna is the Dai people. They live in bamboo houses, eat bamboo rice, celebrate the water-splashing festival and dance peacock dance.

12, Xishuangbanna has long been dominated by agricultural production, and now tourism has developed into a leading industry.

Chapter VIII Inter-provincial Regions

1. The Loess Plateau is the largest loess distribution area in the world, and the aeolian theory is generally accepted about the formation of the Loess Plateau.

2. The Loess Plateau starts from Taihang Mountain in the east, reaches Wushaoling Mountain in the west, Qinling Mountain in the south and the Great Wall in the north. There are three basic landforms in the Loess Plateau: loess plateau, loess beam and loess headland.

3. The loess plateau has broken ground, high valley density, less flat land and many slopes, and vertical steep cliffs are common on both sides of the valley.

4. The loess on the Loess Plateau is loose in structure, with many gaps and vertical cracks, and many substances are easily soluble in water.

5. The Loess Plateau has a temperate monsoon climate, and the precipitation is concentrated in July and August, with heavy rain.

6. The Loess Plateau is bare and lacks vegetation protection. Due to people's unreasonable reclamation, mining and road construction activities, the surface vegetation has been destroyed and soil erosion is serious.

7. Generally speaking, the greater the slope of the ground, the longer the slope, the more precipitation, the greater the intensity of precipitation, the less vegetation on the ground, and the more serious the soil erosion.

8. Soil erosion in the Loess Plateau has taken away the fertile soil on the surface and reduced crop production; Increase, expand and deepen the valley, resulting in a decrease in cultivated land area; It also transported a lot of sediment to the Yellow River, which caused great difficulties in river regulation and flood control.

9. The most serious soil erosion areas in China are the Loess Plateau, Sichuan Basin and Yunnan-Guizhou Plateau.

10. Loess Plateau is characterized by broken terrain, arid climate, serious soil erosion and frequent natural disasters.

1 1. The main natural disaster in the Loess Plateau is flood, which has caused many geological disasters such as mudslides, landslides and collapses.

12, the control of loess plateau adopts the combination of biological measures and engineering measures; Reasonable arrangement of production activities; In addition, strictly controlling population growth and solving the contradiction between man and land are also fundamental governance measures.

The leading industry in the Loess Plateau is energy industry.

13. The Yangtze River runs from Panzhihua in Jiangxi to Shanghai in the east, which is a long and narrow "strip" region from east to west.

14, the terrain along the river is low and flat, and the terrain is mainly plain and low hills; The climate belongs to subtropical monsoon climate, with high temperature and rainy weather; Affected by topography and climate, there are many rivers and lakes, which are the areas with the richest surface water resources in China. There are also abundant hydropower, forests, minerals, aquatic products and cultivated land resources along the Yangtze River.

15, the Yangtze River connects the economically developed coastal areas and the resource-rich western areas along the Yangtze River, which is the link between the east and the west.

16. The Yangtze River is the lifeline for the establishment and development of coastal cities. Among them, Shanghai, Nanjing, Wuhan and Chongqing are regional economic, cultural and transportation centers, which have a strong radiation and driving role in regional economic development.

17, Shanghai is the largest city in China, the largest commercial center, industrial center, the largest port, and also an important financial, scientific and educational center, which plays a leading role in the economic development of the Yangtze River Delta, the Yangtze River and even the whole country.

The Yangtze River is a highly developed comprehensive industrial zone in China. From west to east, steel and coal industrial bases centered on Panzhihua and Liupanshui have been formed. Electric power and metallurgical industrial bases centered on Yichang and Chongqing; An important steel and textile industrial base centered on Wuhan; Shanghai, Nanjing, Hangzhou and other cities form the largest comprehensive industrial base in China.

19. There are automobile and motorcycle bases along the Yangtze River in China, which constitute the automobile industry corridor along the Yangtze River.

20. In recent years, due to the steep slope in the upper reaches of the Yangtze River, the forest area has been reduced and soil erosion has been serious, which has led to the decline of soil fertility and the siltation of rivers, reservoirs and lakes, which has aggravated the flood disaster in the lower reaches.

2 1. The middle and lower reaches of the Yangtze River are the most concentrated, serious and frequent flood disasters in the Yangtze River basin.

22. Acid rain is a phenomenon of air pollution. Precipitation with PH less than 5.6 becomes acid rain, which causes corrosion hazards to water and soil, plants and buildings. The main acid rain areas in China are Southwest China, Central China and East China, among which Central China is the most polluted area by acid rain.

23. The basic national conditions of China are vast territory and great regional differences; It has a large population and a low per capita GNP.

24. The Three-North Shelterbelt covers the northwest, north and northeast of China and is the largest ecological shelter forest in the world.

25. The main problems facing mankind are population, resources and environment.

Chapter 5:

1, there are many different types of geographical areas, some are natural areas, such as the Pearl River Delta; Some are economic zones, such as industrial zones; Some are administrative districts, such as Xizang Autonomous Region. The same geographical area may have multiple identities at the same time.

2. According to the different geographical location, natural and human geographical features, China can be divided into four geographical regions, namely, northern region, southern region, northwest region and Qinghai-Tibet region. Among them, Qinling Mountain and Huaihe River are the dividing lines between the northern region and the southern region.

3. There are obvious differences in topography, climate, river flow and vegetation types between the north and the south of China. Affected by the natural environment, people in the north and the south also have great differences in production methods, living habits and cultural traditions.

Comparison of differences between south and north of China:

Qinling-North of Huaihe River-Qinling-South of Huaihe River Comparison Project

1 (higher/lower than 0) The monthly average temperature is lower than 0 and higher than 0.

The annual precipitation is small.

The main terrain is dominated by plains and plateaus, and plains, basins, plateaus and hills crisscross.

Vegetation type temperate deciduous broad-leaved forest subtropical evergreen broad-leaved forest

The river flow is small and large.

Farming system: one crop a year or three crops a year or two crops a year.

Cultivated upland paddy field

Cereal crops wheat and rice

Traditional means of transportation, carriages and boats

Traditional sports include skiing, skating, dragon boat racing and swimming.

4. The topography of northwest China is mainly plateaus and basins. The eastern part is dominated by grassland and desert landscape; There is a large area of desert in the western basin; Only rare oases appear at the edge of the basin. All these show that the northwest region is a region with drought as its main natural feature.

5. Qinghai-Tibet region is a unique region because of its high terrain, and another obvious natural feature that comes with "high" is "cold".

6. Northwest China and Qinghai-Tibet are the main pastoral areas in China. Inner Mongolia is mainly temperate grassland pasture; Xinjiang is mainly mountainous pasture; Qinghai and Tibet are mainly alpine pastures. Three rivers and three cows in Inner Mongolia, fine wool sheep in Xinjiang, yak in Qinghai-Tibet, Tibetan sheep and Tan sheep in Ningxia are all famous livestock breeds.

7. In addition to animal husbandry, people in northwest China also use river water and meltwater from alpine snow and ice to develop irrigated agriculture.

Chapter VI:

1. Beijing is the political and cultural center of the whole country and the center of international exchanges. The Great Hall of the People is the seat of the NPC Standing Committee, and Zhongnanhai is the seat of the Central Committee of the Communist Party of China and the State Council.

2. The urban pattern of the Forbidden City in Beijing is "convex", which is the representative work of the planning and construction of China's historical capitals.

There are countless places of interest in Beijing, such as the Great Wall, the Summer Palace, the Temple of Heaven and Zhoukoudian Peking Man Site.

Among them, the Forbidden City in Beijing is the largest and most well-preserved palace complex in the world.

4. In order to enhance international competitiveness and service functions, on the one hand, Beijing has intensified infrastructure construction, and planned and built key functional areas including the Central Business District and the International Media Avenue, as well as urban rapid rail transit and expressway; On the other hand, actively develop high-tech industries, improve urban management efficiency and service quality, and build a harmonious urban environment between people and the environment.

5. Hong Kong consists of Hong Kong Island, Kowloon Peninsula, New Territories and more than 200 surrounding islands, while Macao consists of Macao Peninsula, Taipa Island and Coloane Island. Hong Kong and Macao are among the regions with the highest population density in the world.

6. Hongkong and Macau are two special administrative regions of China. Our government has formulated the policy of "one country, two systems", and China's mainland implements the socialist system, while Hong Kong and Macao implement the capitalist system.

7. Hong Kong has a large population but a small population. "Going to heaven"-building tall buildings and "going to sea"-reclaiming land from the sea have become two important ways for Hong Kong to expand its urban construction land.

8. The tertiary industry in Hong Kong and Macao is very developed. Hong Kong is an international trade center, transportation center, financial center, information service center and tourism center. Gambling tourism is an important pillar industry of Macao's economic development.

9. For a long time, Hong Kong and Macau have maintained close economic ties with the mainland of China, especially Hong Kong. Mainland China is rich in natural and labor resources, and Hong Kong is rich in capital, technology, talents and management experience. The economic cooperation between Hong Kong and the mainland of China is complementary and mutually beneficial.

10, entrepot trade refers to the form of trade in which goods purchased from one country are sold directly to other countries instead of being sold locally. Mainland China is Hong Kong's largest entrepot trading partner.

1 1. Taiwan Province Province includes Taiwan Province Island, and many small islands such as Penghu Islands and Diaoyu Islands nearby. Taiwan Province Island is the largest island in China, bordering the East China Sea in the north, the Pacific Ocean in the east, the South China Sea in the south and Fujian Province across the Taiwan Province Strait in the west.

12, Taiwan Province Island is a rich treasure island, known as "the pearl of the southeast sea of the motherland". About half of the land on the island is covered with dense forests and has the reputation of "Asian Natural Botanical Garden". Cinnamomum camphora is the most famous tree species in Taiwan Province Province, and its camphor production ranks first in the world.

13. Before the 1960s, the economy of Taiwan Province Province was dominated by agriculture and agricultural products, exporting cane sugar, pineapple, rice and camphor. Since 1960s, Taiwan Province Province has focused on developing export processing industry, forming an "import-processing-export" economy.

14, Xinjiang Uygur Autonomous Region is the largest province in China. The mountains and basins in Xinjiang are distributed alternately, forming the topographical features of "three mountains and two basins". The majestic Tianshan Mountains span the central part of Xinjiang, with Tarim Basin and Junggar Basin on the north and south sides respectively.

15. There are thousands of oases in Xinjiang, which is the most important agricultural production base. Wheat, corn and sorghum are the main crops here, and cotton, sugar beet and various melons and fruits have become the characteristic agricultural products of Xinjiang Oasis. Karez is an ancient water diversion project, which has been used by oasis residents in Xinjiang for a long time.

16, the predicted oil and gas reserves in Xinjiang account for about 1/3 of the total land reserves in China. With the gradual implementation of the national energy strategic decision of "stabilizing the east and vigorously developing the west", Xinjiang is expected to become an important oil and gas industrial base in China. The implementation of the West-to-East Gas Transmission Project will rapidly increase the local fiscal revenue and alleviate the energy shortage in the eastern region.

Chapter 7:

1. The Pearl River Delta is located in the southeast of Guangdong Province, with convenient land and water transportation, and is known as the "South Gate" of China.

The Pearl River Delta region has formed a multi-level open system including special economic zones (Shenzhen and Zhuhai), coastal open cities (Guangzhou) and economic open areas (the whole Pearl River Delta).

2. Taking advantage of the superior conditions here, the Pearl River Delta has attracted a lot of overseas Chinese investment (the main source of foreign investment in the Pearl River Delta is Hong Kong and Macao) and has become the frontier of China's opening up.

3. Since 1980s, the Pearl River Delta has taken advantage of its superior geographical position adjacent to Hong Kong and Macao, accepted the industrial diffusion of Hong Kong and Macao nearby, introduced a large number of foreign capital, introduced advanced technology and equipment, management methods and the latest industrial and commercial science and technology information, established a large number of processing and manufacturing enterprises, and developed an export-oriented economy.

The products produced in the Pearl River Delta are mainly exported to Southeast Asia, Europe, Africa, America, Oceania and other regions through Hong Kong and Macao trade channels, earning a lot of foreign exchange. By the end of the 20th century, it has become one of the largest production and export bases of electronic and daily consumer goods in the world.

5. The cooperation between Hong Kong, Macao and the Pearl River Delta region is based on "store in front and factory in back". Hong Kong uses the overseas trade window to conduct marketing and external sales, and plays the role of "shop". The Pearl River Delta region takes advantage of land, natural resources and labor force to process, manufacture and assemble products, and plays the role of "factory".

6. The development of processing and manufacturing industry in the Pearl River Delta has promoted the development of service industries such as catering, entertainment and transportation. These non-agricultural industries provide a large number of employment opportunities for local surplus labor and also absorb millions of foreign labor.

7. With the development of non-agricultural industries and the migration of population, more and more agricultural land in the Pearl River Delta has been transformed into industrial, transportation and urban construction land. These non-agricultural land is adjacent to the remaining agricultural land, forming a unique land use landscape with staggered distribution of residential land, industrial land, infrastructure land and agricultural land.

8. Xishuangbanna is the most intact place in China's pristine tropical rain forest except Hainan Province. The towering trees, huge packing, cruel strangled plants and majestic "single tree into forest" are all unique landscapes of the rainforest.

There are thousands of animals living in Xishuangbanna, including Asian elephants, green peacocks and other national key protected animals. People vividly call it "the kingdom of tropical animals".

10, Xishuangbanna is still a place where ethnic minorities live in concentrated communities, and the multi-ethnic customs with Dai as the main body have added infinite charm to Xishuangbanna.

1 1. For a long time, Xishuangbanna has been dominated by agricultural production. Since the mid-1980s, with the encouragement of the relevant policies of the state and Yunnan Province, Xishuangbanna, with its unique location and resource advantages, has made tourism rise rapidly and become an important pillar industry.

Chapter 8:

1. The largest loess accumulation area in the world is the Loess Plateau, which is one of the areas with the most serious soil erosion in the world.

2. Soil erosion takes away the fertile soil on the surface and reduces the crop yield; Increase, expand and deepen the valley, thus reducing the cultivated land area; It also transported a lot of sediment to the lower reaches of the Yellow River, which caused great difficulties in river regulation and flood control.

3. The loess plateau has a broken terrain and a relatively dry climate, which not only causes serious soil erosion, but also causes frequent natural disasters. Drought and flood disasters are the most important natural disasters in the Loess Plateau, so the ecological environment of the Loess Plateau is very fragile.

4. In order to realize the sustainable development of social economy in the Loess Plateau, we must strengthen ecological construction and improve the environment. On the one hand, biological measures such as planting trees and grass should be combined with engineering measures such as terraced fields and earth dams to control soil erosion; On the other hand, reasonable arrangements should be made for production activities, such as returning farmland to forests and grasslands on steep slopes, and reducing the number of grazing livestock in overgrazing areas.

5. The area along the Yangtze River is a typical "banded" area, which is not only superior in geographical position, but also endowed with unique natural conditions, laying a solid foundation for the development of this area and being the center of national economic development.

6. The Yangtze River along the Yangtze River connects the economically developed coastal areas with the resource-rich western areas, forming an English letter "H" pattern, which is the link between the east and the west.

7. The area along the Yangtze River is an important agricultural area in China with a solid industrial base. At present, it has developed into one of the most dynamic high-tech industrial development zones in China. Through many north-south tributaries and traffic arteries, these economic and technological advantages can radiate north and south, and make China's north-south economy integrate.

8. There are many cities along the Yangtze River, with dense towns in the middle and lower reaches and few cities in the upper reaches. Among them, Shanghai, Nanjing, Wuhan and Chongqing are regional economic, cultural and transportation centers, which have a strong radiation and driving role in regional economic development. On the basis of these four megacities, four urban agglomerations centered on them have been formed respectively.

9. The Yangtze River is a highly developed comprehensive industrial zone in China. At present, four industrial bases have been formed from east to west. There are industrial bases such as steel, petrochemicals, automobiles and textiles along the Yangtze River, which constitute the embryonic form of China's east-west "industrial corridor".

10. During the development along the Yangtze River, a series of ecological and environmental problems have emerged, such as soil erosion, flood disaster (the middle and lower reaches of the Yangtze River are the most concentrated, serious and frequent areas of flood disaster in the Yangtze River basin), water pollution, acid rain and so on.

1 1. Acid rain will lead to acidification of water and soil, causing corrosion hazards to plants and buildings. The acid rain area in Central China is the largest acid rain pollution area with the highest central intensity in China, and the acid rain area in Southwest China is the second most serious acid rain area. The pollution intensity in East China is lower than that in Central China and Southwest China.

Chapter 9:

1, with vast territory and great regional differences, is a basic national condition of our country. To achieve sustainable development, a region needs to develop its economy according to local conditions and strengthen the ties between regions.

2. A large population and a low per capita GNP is another basic national condition of our country. The world in the 21st century is a world of economic globalization. China should actively integrate into the process of economic globalization and seek development in the world.
