Regional Geomorphological Factors of Landscape Formation
The regional variations in the Earth’s surface control the formation of the regional landscapes, including highlands, mountains, hills, basins and plains. Mountains can be classified based on their heights as high, medium and low mountains and hills. Mountains with relative heights over 1,000 m are classified as deeply eroded mountains, those with relative heights of 500–1,000 m are moderately eroded mountains, and those with relative heights of 200–500 m are slightly eroded mountains. China’s regional landscape is composed of three geomorphological plateaus that are separated by mountain ranges, which have essentially controlled the types and distribution of natural landscapes in China.
