摘  要：
区域生态敏感性评价对于制定区域社会经济发展政策,有效进行环境管理具有重要作用。利用GIS技术,以贵州省仁怀市为研究对象,运用单因子敏感性评价和综合敏感性评价两种方法,选择土地利用、高程、坡度、水系、地质灾害作为评价因子,对仁怀市生态敏感性及其空间分布进行了研究。结果表明:极敏感区占仁怀市总面积的1.43%,主要分布在高海拔山区;敏感区占17.76%,分布在沿河地区以及山麓地区;低敏感区占57.41%,分布在中低山地区;不敏感区占23.40%,主要分布在城镇区域。结合生态敏感性,提出了各区块的生态环境建设和保护对策,以期为仁怀市区域生态环境保护提供决策依据。

摘  要：
Regional ecological sensitivity analysis is an effective tool for making regional social and economic development policies and environmental management.Taking Renhuai City of Guizhou Province as the research area,sensibility and its spatial distribution were studied in views of the sensitivities to land use,elevation,slope,water system,geological disasters under support of GIS technologies.Single and comprehensive element sensitivity assessment is used in the study.Results show that the extreme sensitive area accounts for 1.43% of the total area,which mainly lies in high altitude mountain.The sensitive area accounts for 17.76%,which distributes in valley and foothills.The low sensitive area accounts for 57.41%,which distributes in low mountain.The insensitive area accounts for 23.40%,which distributes in urban areas.By combining with the result of eco-environmental sensitivity assessment,countermeasures for eco-environmental construction and protection of each of the areas are proposed and a basis for government making policy is provided.
