Differences of Ethnic Folklore in Four Geographical Regions of China

North China, Northeast China, Northwest China and Southeast China

According to geographical differences and climate differences

1. China has a vast territory, spanning longitude and latitude, which directly leads to the division of four geographical regions. Read Figure 5.4 "Four Geographical Regions of China". First, through the specific distribution of boundary A, boundary B and boundary C, determine the positions of the four geographical regions.

2. According to the prompt of activity 1, observe the boundary between monsoon area and non-monsoon area and the boundary A between northern area and northwest area, and guide students to analyze the similarity of the two boundaries, which shows that the dominant factor of regional division here is the influence of monsoon. Northwest China is deep inland, not affected by monsoon, with less precipitation, which reflects the regional characteristics of drought, while the north and south areas located in the eastern monsoon area are affected by monsoon, with more precipitation and are in humid and semi-humid areas.

3. Observe the position of the boundary line B according to the tips in Activity 2. Students should look for the 1 isotherm and isoprecipitation line corresponding to their position in the 1 isotherm and annual precipitation distribution map. The results are10,65438 0℃ isotherm and 800 mm isoprecipitation line respectively. From this, the boundary B is divided into the southern region and the northern region, and the main regional differences are manifested in the comprehensive climate of temperature and precipitation. Finally, according to the prompt, the 0℃ isotherm of 1 month and the 800 mm isorainfall line are determined from the topography and river distribution map, which are located in the Qinling-Huaihe line. It may be slow for students to find answers one by one according to the questions in the textbook, but teachers should avoid telling students the answers directly and leave enough time and space for students' inquiry learning.

4. According to the tips in Activity 3, observe that the position of boundary C coincides with the boundary of the first step in China. After students find that the boundary C is very consistent with the boundaries of the first and second levels of Chinese topography, they can judge that the dominant factor in dividing the Qinghai-Tibet region from the southern region, the northern region and the northwest region is the topographic factor.
