基于GIS的芜湖市生态敏感性评价

Ecological Sensitivity Assessment of Wuhu City Based on GIS

本文以芜湖市为研究区,选取6个生态敏感性评价因子,包括坡度、坡向、水环境、植被覆盖度(NDVI)、土地利用类型和人口密度,利用地理信息系统(GIS)和层次分析法(AHP)对芜湖市生态敏感性进行评价,明确不同土地生态敏感性分区的空间分布格局。在生态敏感性评价的基础上,针对不同的土地生态敏感性分区提出保护与利用建议,为国土空间规划提供方向。

Taking Wuhu City as the research area,this paper selects six ecological sensitivity evaluation factors,including slope,aspect,water environment,normalized difference vegetation index(NDVI),land use type,and population density,and uses geographic information system(GIS) and analytic hierarchy process(AHP) to evaluate the ecological sensitivity of Wuhu City,clarifying the spatial distribution pattern of different land ecological sensitivity zones.On the basis of ecological sensitivity assessment,protection and utilization suggestions are proposed for different land ecological sensitivity zones,providing direction for national spatial planning.
