摘　　要：城市湿地是城市重要的自然资源,是城市生态系统的重要组成部分.近年来,随着我国城市化进程的进一步加快,城市湿地受到各种自然和人为的干扰和胁迫,出现了多种生态环境问题.本文以长治湿地为例,选取对湿地生态影响较大的因子:土地利用、植被覆盖、地形地貌、洪水分析等4个方面7个指标,建立了多要素的空间评价模型.利用GIS空间分析模块和叠置分析模块,采用空间多成分综合分析方法,进行生态敏感度单因子分析和敏感度综合评价,并将评价结果划分为四个等级:低敏感区、一般敏感区、较高敏感区以及高敏感区,获得了长治湿地公园生态敏感度空间分布规律.在此基础上,提出针对各敏感度等级的控引方案,可以为长治湿地公园规划及生态环境保护措施的实施提供依据.As an important natural resource of city,urban wetland is a significant component of the urban ecosystem.In recent years,with the continually speeding up of the urbanization,urban wetlands have been interfered and threatened by various natural and man-made factors,and appeared a variety of ecological problems.This paper takes Changzhi wetland as an example;selecting 7indicators of 4influential factors to wetland ecological environment：land use,vegetation,topography,flood analysis,building a spatial evaluation model of multi-factor;Based on the spatial analysis and superimposed analysis module of GIS,using comprehensive analysis method-space composition,carrying on the sensibility assessment of single factor and comprehensive indicators,and the evaluation results is divided into four levels：low sensitivity,the general sensitive area,high sensitivity and higher sensitivity,obtaining the spatial distribution of Changzhi Wetland Park＇s ecological sensitivity.On the basis of sensibility assessment,this paper puts forward some control schemes corresponding to different sensibility,and provides the basis for changzhi wetland park＇s developping plan and the implementation of the ecological environment protection measures.
