In this paper, five sensitivity factors affecting the eco-environment of Shanghai City, i.e., rivers and lakes, historical relics and forest parks, geological disasters, soil pollution, and land use, were selected, and their weights were determined by analytic hierarchy process. Combining with GIS spatial analysis technique, the sensitivities of these factors were classified into four grades, i.e., highly sensitive, moderately sensitive, low sensitive, and insensitive, and the spatial distribution of the ecological sensitivity of Shanghai City was figured out. There existed a significant spatial differentiation in the ecological sensitivity of the City, and the insensitive, low sensitive, moderately sensitive, and highly sensitive areas occupied 37.07%, 5.94%, 38.16%, and 18.83%, respectively. Some suggestions on the City's zoning protection and construction were proposed. This study could provide scientific references for the City's environmental protection and economic development.
本文选取了影响上海市生态环境的五个敏感性因素，即河湖、历史遗迹与森林公园、地质灾害、土壤污染和土地利用，并采用层次分析法确定其权重。结合GIS空间分析技术，将这些因素的敏感性划分为高度敏感、中度敏感、低度敏感和不敏感四个等级，得出上海市生态敏感性的空间分布情况。上海市生态敏感性存在显著的空间分异，不敏感、低度敏感、中度敏感和高度敏感区域分别占37.07%、5.94%、38.16%和18.83%。针对上海市的分区保护与建设提出了一些建议。本研究可为上海市的环境保护和经济发展提供科学参考。
