Abstract: The 45 families and 97 genera and 128 species for vegetation restoration were sorted out on the basis of the afforestation tree species selection principle and the method of analysis in arid and semi-arid regions of Sichuan province.The study found that leguminous plants in arid and semi-arid areas of Sichuan were most widely used to restore vegetation.The related research focused on dry hot valleys and dry warm valleys in Sichuan,but the study of dry temperature and Derong-Xiangcheng semi-arid areas needed to be further strengthened.
