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2801~4000 m的缓坡、斜坡和陡坡区域;冷杉主要分布于海拔3201~4400 m的缓坡、斜坡和陡坡区域;高山松主要分布于海拔2801~4000 m的缓坡、斜坡和陡坡区域。
This analysis selects three main forest types in Diqing Prefecture-Picea brachytyla var.complanata,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 distributed in areas with an elevation of 2801~4000 m on gentle slopes,moderate slopes,and steep slopes;Abies georgei is mainly distributed in areas with an elevation of 3201~4400 m on gentle slopes,moderate slopes,and steep slopes;Pinus densata is mainly distributed in areas with an elevation of 2801~4000 m on gentle slopes,moderate slopes,and steep slopes.
