Abstract: In this paper,on the basis of the "moderate" afforestation technology proposed in the process of vegetation restoration in the dry hot valley,and according to the natural vegetation succession,soil water carrying capacity and site heterogeneity,discussion was made on the "moderation" density of afforestation in stand structure and the "moderation" community allocation of vegetation restoration on the regional landscape scale from the perspective of systematic and quantitative research.The "moderation" afforestation techniques and theories were further illustrated in order to provide reference for research and practice of vegetation restoration in the dry hot valley.
