What are the topographical features of China?

China's topography is high in the west and low in the east, showing a ladder-like distribution; The terrain is changeable and the mountains are vast. The terrain is high in the west and low in the east, leaning towards the ocean. On the one hand, it is beneficial for the moist air flow on the ocean to penetrate into the mainland and form precipitation; On the other hand, many large rivers flow eastward, connecting east-west traffic and promoting economic ties between coastal areas and inland areas.

The river drops step by step from west to east, with a large drop and rich water energy. The diverse terrain provides favorable conditions for developing diversified management of agriculture, forestry, animal husbandry and agriculture according to local conditions. Mountain areas have advantages in developing forestry, animal husbandry, tourism and mining. However, the rugged terrain and inconvenient transportation in mountainous areas are not conducive to the development of planting. Due to the vast mountains, few plains and insufficient cultivated land resources.

Terrain ladder

Topography is the general trend of surface fluctuation. China's topography is high in the west and low in the east, and it is generally ladder-shaped. The topography of high in the west and low in the east is conducive to the warm and humid air flow in the Pacific Ocean going deep into the inland areas, and the cold air in the north can go south for a long time, which is conducive to the formation of precipitation. The topography of high in the west and low in the east makes the rivers in China flow into the sea from west to east, connecting the eastern and western parts, the coastal areas and the inland areas. ?

The first step of the terrain is the Qinghai-Tibet Plateau, with an average elevation of more than 4,500 meters. Its northern and eastern edges are divided by Kunlun Mountain, Qilian Mountain, Hengduan Mountain and the second terrace topography.

The average elevation of the second terrace is between1000-2000m, in which there are large basins and plateaus. The eastern part is bounded by Daxing 'anling, Taihang Mountain, Wushan Mountain, Xuefeng Mountain and the third terrace terrain.

The third step of the terrain is a vast plain, with hills and low mountains in the middle, most of which are below 500 meters above sea level.

The third step from land to sea in China is the continental shelf, which is a natural extension of the mainland to the sea. Generally, the depth is not large, the slope is gentle and the marine resources are abundant. China's offshore continental shelf is relatively broad, and all the seabed in Bohai Sea and Yellow Sea, most of the seabed in the East China Sea and part of the seabed in the South China Sea belong to the continental shelf. The exploitation of marine resources, especially petroleum resources, is mainly on the continental shelf.
