摘    要:    以杭州市为研究对象,充分运用GIS空间分析功能,对杭州市生态系统的土壤侵蚀敏感性、生境敏感性和酸雨敏感性等环境因子进行评价,并通过多因子加权求和模型进行综合分析,结果表明杭州市生态系统敏感性在空间分布上呈显著差异性,低度敏感区、中度敏感区和高度敏感区分别占总面积的10.91%、59.63%和29.46%.结合生态敏感性,提出了各区块的环境保护对策和产业调整方向,为杭州市未来产业布局与区域生态环境保护提供决策依据.

关 键 词:城市生态系统  生态敏感性  空间分析  杭州市

Abstract:Eco-sensitivity evaluation is a base for ecological regionalization.The ecological factors including sensitivities to soil erosion,to bio-diversity protection and to acid rain in Hangzhou were analyzed by using global information system(GIS) technology and the model of multifactor summation with different weight in this paper.The results show that the difference of spatial distribution between these factors was significant,and the spatial area of Hangzhou ecosystem can be divided into sub-region of weak,medium,and high sensitivity,with the individual areas of these sub-regions amounting to 10.91%,59.63% and 29.4% of the total area respectively.In light of the assessment result of eco-sensitivity,the actions of environmental protection and the design of industry development are suggested for supporting to national distribution of industrial and regional environment protection.
Keywords:urban ecosystem  eco-sensitivity  spatial analysis  Hangzhou City
