| 摘 要： | 生态保护红线是国家和区域生态安全的底线,以阿坝州汶川县划定的生态保护红线区为研究区域,利用GIS软件对研究区域内人类活动遥感影像进行遥感解译,并对研究区生态保护红线内的人类活动进行本底实地调查,结合遥感解译和实地调查结果,对红线内人类活动强度进行了评价。结果表明:红线内人类活动面积共计142.04hm2,人类活动斑块数量共计281个;红线内的人类活动影响指数为0.019,人类活动影响强度弱;红线内人类活动影响类型主要为旅游活动和耕地、道路及居民点等。

| Abstract: | The red line of ecological protection is the bottom line of national and regional ecological security.This paper takes the ecological protection red line area in Wenchuan County of Aba Prefecture as the research area,GIS software was used to interpret remote sensing images of human activities in the study area,and background field survey of human activities in the ecological protection red line was carried out in the study area.Based on the results of remote sensing interpretation and field investigation,the intensity of human activities within the red line in Wenchuan County was evaluated.The results showed that the area of human activity in the red line was 142.04hm2,and the number of human activity patches was 281.Within the red line,the impact index of human activities is 0.019,indicating the intensity of human activity influence is weak.The main types of human activities in the red line are tourism activities,cultivated land,roads and residential areas. |
