This analysis selects three main forest types in Diqing Prefecture—Picea brachytyla var.com-planata,Abies georgei,and Pinus densata—as research objects.Using DEM data,topographic factors such as elevation,slope,and aspect were generated.Combined with the results of the 2017 second-class forest resource survey in Diqing Prefecture,the spatial distribution characteristics of the three types of pine forests were analyzed.The results show that Picea brachytyla var.complanata is mainly distribu-ted in areas with an elevation of 2 801～4 000 m on gentle slopes,moderate slopes,and steep slopes;Abies georgei is mainly distributed in areas with an elevation of 3 201～4 400 m on gentle slopes,moder-ate slopes,and steep slopes;Pinus densata is mainly distributed in areas with an elevation of 2 801～4 000 m on gentle slopes,moderate slopes,and steep slopes.
