摘要
基于滇西北区域林地变更成果、高分辨率卫星影像等数据,采用影像判读确定滇西北区域的重要生态系统类型,采用随机抽样方法对初步成果进行实地验证。结果表明:滇西北重要生态系统总面积为4494278.26 hm^(2),占滇西北土地总面积的76.96%,其中暖温性针叶林生态系统占比最大为23.10%,在滇西北各县均有分布;香格里拉市分布的重要生态系统面积最大,寒温性针叶林、温凉性针叶林和高寒山地硬叶常绿阔叶林生态系统主要分布于香格里拉市;纳入保护地的重要生态系统面积占滇西北重要生态系统面积的77.32%。
Based on the data of forest land change and high-resolution satellite images in northwest Yunnan,the important ecosystem types in the region were determined by image interpretation and the preliminary results were verified by random sampling.The results showed that the total area of important ecosystems in northwest Yunnan was 4494278.26 hm^(2),accounting for 76.96%of the total land area in northwest Yunnan,among which,the warm coniferous forest ecosystem accounted for 23.10%of the total area of important ecosystems,which was distributed in all counties of northwest Yunnan;the important ecosystem area distributed in Shangri-La was the largest,mainly distributed with cold-temperate coniferous forests,warm cool coniferous forests,and alpine hard-leaved evergreen broad-leaved forest;the area of important ecosystems included in natural protected areas accounted for 77.32%of the area of important ecosystems in northwest Yunnan.
