摘　　要：选取Pléiades卫星数据、数字地形图、珍稀植物分布图等主要数据,在RS和GIS技术的支持下,从土壤侵蚀和生境两方面评价九寨沟旅游区生态敏感性.研究过程中,以海拔200 m作为分区标准,将旅游区划为6个分区,然后对6个分区的生态敏感性分别开展评价.研究结果表明:各分区均为土壤侵蚀中度敏感区;I、II和III区为生境高度敏感区,其他分区为生境极敏感区,生境敏感性等级随海拔增加表现出一定的变化.Pléiades data,digital typography map and spatial distribution map of rare plant were selected in the paper with the support of RS and GIS technology to evaluate,the ecological sensitivity of the tourism area on soil erosion and bio-inhabitation. In order to analyze the spatial distribution characteristics of the ecological sensitivity,200 meter of elevation was chosen as the zoning standard and the tourism area was classified into 6 subareas. Then,the ecological sensitivity of each subarea was evaluated,respectively. The results indicate that all subareas were the moderate sensitive areas of soil erosion sensitivity. As to bio-inhabitation sensitivity,subarea I,II and III are the strong sensitive areas while other subareas are the extreme sensitive areas. The level of bio-inhabitation sensitivity changes with the increase of elevation.
