摘　　要：选取地形地貌因子(主要包括高程、坡度、坡向)、水体缓冲区、NDVI、土地利用类型四大类指标,综合单因子分析及多因子加权叠加的方法,利用ArcGIS分析技术和层次分析法对咸丰县生态敏感性的空间格局进行分析,得出各单因子及多因子综合性评价图。结果表明:咸丰县综合生态敏感性强度整体上由西北和东南向中部降低,研究区的极低敏感区、轻度敏感区、中度敏感区、高度敏感区和极高敏感区面积占研究区总土地面积的比重依次为0.87%、14.96%、27.89%、35.51%、20.77%。Selecting four major categories of indicators:terrain and geomorphic factors(mainly including elevation,slope,aspect),water buffer zone,NDVI and land use type,using single factor analysis and multi factor weighted superposition methods,ArcGIS analysis technology and Analytic Hierarchy Process were used to analyze the spatial pattern of ecological sensitivity in Xianfeng County,and comprehensive evaluation map of each single factor and multi factor was obtained.The results showed that the overall ecological sensitivity intensity of Xianfeng County had decreased from northwest and southeast to central.The proportion of the areas of extremely low sensitivity,mild sensitivity,moderate sensitivity,high sensitivity and extremely high sensitivity in the total land area of the study area was 0.87%,14.96%,27.89%,35.51%and 20.77%,respectively.
