摘　　要：生态敏感性评价能够为区域的发展规划以及生态环境保护提供科学依据。以典型的山地生态城市闽侯县为研究区域,选取高程、坡度、坡向、水域缓冲、植被覆盖指数(NDVI)、土地利用等6个生态敏感因子,采用层次分析法(AHP)结合变异系数法来共同确定各指标因子权重,利用GIS技术对闽侯县进行生态敏感性评价。结果表明:闽侯县的总体敏感程度较高,水域和植被是其主要的敏感因素;极度敏感区、高度敏感区、中度敏感区、轻度敏感区、不敏感区面积占比分别为10.52%、33.80%、28.92%、18.33%、8.43%。此研究结果为闽侯县的生态可持续发展策略和分区保护提供了一定的科学参考。Ecological sensitivity evaluation can provide scientific basis for the regional development planning and protection of ecological environment.A typical mountainous ecological city(Minhou County)is used as case study,the six ecological sensitivity factors,such as elevation,slope,slope direction,water buffer zone,vegetation coverage index and land use,are selected.Analytic Hierarchy Process(AHP)and variation coefficients were applied to determine the weight of each index,and evaluate the ecological sensitivity of Minhou County using GIS technology.The results show that the overall sensitivity of the study area is high,water area and vegetation are the main sensitive factors;The proportion of the area of the extremely sensitive area,the highly sensitive area,the moderately sensitive area,the mildly sensitive area and the non-sensitive area is 10.52%,33.80%,28.92%,18.33%and 8.43%respectively.The results of this study provide some scientific reference for the ecological sustainable development strategy and the regional protection of Minhou County.
