摘　　要：利用GIS软件对郑州市进行生态敏感性分析,并进行生态敏感性区划划分,选取植被覆盖度、高程、坡度、水域缓冲区、人口密度、土地利用类型6个因子,采用模糊层次分析法(FAHP法)构建评价模型,利用GIS软件的空间分析功能,分析单因子生态敏感性以及加权叠加的综合生态敏感性。结果表明,郑州市整体以中度敏感区为主,其次为高度敏感区;中度敏感区占研究区总面积的37.05%,主要分布于郑州市北部黄河流域、东部平原以及西部嵩山周边区域;高度敏感区占研究区总面积的29.19%,主要分布于嵩山、箕山坡度较大的低山丘陵区;低敏感区占研究区总面积的21.03%,主要分布于郑州市北部黄河水域及东部的城市中心规划区周边区域;不敏感区占研究区总面积的12.73%,主要分布于郑州市东部的市中心区及下辖的中牟县、新郑市城市建成区域,西部局部地区也有零散分布。Using GIS software,ecological sensitivity analysis was conducted in Zhengzhou City,and ecological sensitivity zoning was carried out.Six factors were selected,including vegetation coverage,elevation,slope,water buffer zone,population density,and land use type,the fuzzy analytic hierarchy process(FAHP)was used to build the evaluation model,and the spatial analysis function of GIS software was used to analyze the ecological sensitivity of a single factor and the comprehensive ecological sensitivity of weighted superposition.The results indicated that Zhengzhou City was mainly composed of moderately sensitive areas,followed by highly sensitive areas;moderately sensitive areas accounted for 37.05%of the research area total area,mainly distributed in Yellow River Basin in the north of Zhengzhou,the plain in the east of city,and the surrounding areas of Songshan Mountains in the west of Zhengzhou City;highly sensitive areas accounted for 29.19%of the research area total area,mainly distributed in low mountain and hilly areas with higher elevations and larger slopes in Songshan and Jishan Mountains;low sensitivity areas accounted for 21.03%of the research area total area,mainly distributed in the Yellow River water area in the north of Zhengzhou City and the surrounding areas of the urban central planning area in the eastern part of Zhengzhou City;the insensitive areas accounted for 12.73%of the research area total area,mainly distributed in the central area in the east of Zhengzhou,the urban built-up areas of Zhongmu County and Xinzheng City under its jurisdiction,and scattered in some parts of the west.
