摘要

通过选取迪庆州内旗舰树种云杉、冷杉和高山松3种主要森林类型为研究对象,利用DEM数据生成海拔、坡度、坡向等地形因子,并结合2017年调查完成的迪庆州森林资源二类调查数据成果,分析研究全州3种松林的空间分布特征.结果显示,迪庆州云杉主要分布于海拔2 801～4 000 m的缓坡、斜坡和陡坡区域;冷杉主要分布于海拔3 201～4 400 m的缓坡、斜坡和陡坡区域;高山松主要分布于海拔2 801～4 000 m的缓坡、斜坡和陡坡区域.

Abstract

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.
