Abstract: This paper explicitly defines the principles, bases, indices and marks of Chinese vegetation regionalization. Chinese vegetation regionalization system was classified into 4 levels. The super level unit is vegetation biome. The whole country can be subdivided into forest biome, grasslands biome, and desert biome. The primary unit is vegetation region, having 14 ones in China. The secondary unit is vegetation zone and the tertiary unit is vegetation area. The above division scheme has fully absorbed the achievements of previous Chinese vegetation regionalization schemes. The borders of many regionalization units, were modified according to the updated materials.
