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 evalu-ation 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,moder-ate 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.
