摘　　要：借助于GIS和RS技术,运用层次分析法,选取影响生态环境的10个因子进行单因子及综合因子评价,分析湖州塘浦(溇港)圩田系统生态空间的环境敏感程度及敏感区分布,构建研究区生态空间敏感性评价体系及生态空间布局优化策略。结果表明:研究区生态空间敏感性分布存在空间异质性,呈现边缘高、中心高、周边低的趋势,敏感性较高的区域为西南部(高程>600 m)及西北部,高、较高敏感区面积为500.06 km^2,占总面积的25.55%。从总体上看,研究区生态空间环境脆弱,生态问题突出,表现为区域内圩田水网布局错位、植被指数较低、溇港淤泥堵塞及高海拔区域圩田供水不足等,地理、自然、人文等因素是影响该区域生态空间敏感性的重要因素。因此,必须通过减少干扰等措施来保护塘浦(溇港)圩田的生境,形成对该区整体生态系统有支撑能力的空间结构体系。With the help of GIS and RS technologies,the AHP evaluation method is used to select 10 factors that affect the ecological environment for single-factor and comprehensive factor evaluation,and to analyze the environmental sensitivity and distribution of sensitive areas in the ecological space of polder land system in Tangpu(Lougang)of Huzhou City,and construct a study ecological space sensitivity evaluation system and optimization strategy of ecological space layout.The results show that there is spatial heterogeneity in the distribution of ecological spatial sensitivity in the study area,showing a trend of high margins,high centers,and low surroundings.The areas with higher sensitivity are the southwest(elevation>600 m)and the northwest.The area of high sensitivity area is 500.06 km2,accounting for 25.55%of the total area.On the whole,the ecological space environment in the study area is fragile,and the ecological problems in the region are prominent.This is manifested by the misplaced water network layout,low vegetation index,silt blockage in the Lougang,and insufficient water supply in the polder land at high altitudes.Geographical factors,natural factors,and human factors are important factors affecting the ecological space sensitivity of the region.Therefore,it is necessary to protect the habitat of the polder land through measures such as reducing interference so as to form a spatial structure system that supports the overall ecosystem of the area.
