Abstract: Vegetation type is the basis for the study of natural vegetation. The CSCS (comprehensive and sequential classification system) model reflects the potential natural vegetation types and their spatial distribution. Therefore, research on the spatial distribution of existing natural vegetation types based on the CSCS model has practical significance in grassland resource monitoring and animal husbandry production management. Based on the potential natural vegetation map of China produced by the CSCS model, the distribution was analysed and divided into typical areas of existing natural vegetation by combining it with the Chinese vegetation map and DEM (digital elevation model) data. This is the first time that the existing natural vegetation distribution map and the typical area of existing natural vegetation distribution map of China have been produced. It will play an important role in the sampling position selection of CSCS-based grassland types in field investigations and in the study of their plant biological characteristics.
