The main topography of China.

China's main landforms: mountains, hills, plains, plateaus and basins.

The main topographic areas of China:

Main plains: northeast plain, north China plain, middle and lower reaches of Yangtze River plain and Pearl River Delta;

Main plateaus: Qinghai-Tibet Plateau, Inner Mongolia Plateau, Yunnan-Guizhou Plateau and Loess Plateau;

Main basins: Junggar basin, Qaidam basin, Tarim basin, Sichuan basin and Turpan basin;

Main hills: Liaodong hills, Shandong hills, Jiangnan hills, Guangdong and Guangxi hills, Zhejiang and Fujian hills.

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.

Extended data:

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.

There are two terrain areas on the first step: Qinghai-Tibet Plateau and Qaidam Basin.

There are six terrain areas on the second step: Tarim Basin, Junggar Basin, Inner Mongolia Plateau, Loess Plateau, Sichuan Basin and Yunnan-Guizhou Plateau.

There are three terrain areas on the third step: the Northeast Plain, the North China Plain and the Middle and Lower Reaches of the Yangtze River.

At the same time, at the transition of the three steps, the river forms a huge gap, which is rich in hydraulic resources, and some large hydropower stations in China are built here.

If you draw a topographic profile of China from west to east through the 32 N line, it is obvious that the western plateau, the central basin and the eastern plain are high in the west and low in the east.

Even in the north or south, the natural environment is very different.
