ABSTRACT
Taking the Guanzhong area of Shaanxi Province as the research object, six sensitivity factors including elevation, slope, normalized vegetation index (NDVI), land use type, precipitation, and water system buffer zone were selected. AHP and variation coefficient methods were used to determine the index weight, and the ecological sensitivity of the Guanzhong area was comprehensively analyzed based on ENVI5.3 remote sensing image processing software and ArcGIS analysis. The results showed that the overall comprehensive ecological sensitivity of Guanzhong increased gradually from northeast to southwest, with non-sensitivity area accounting for 0.76%, low sensitivity area 23.11%, medium sensitivity area 40.85%, high sensitivity area 27.39%, and extreme sensitivity area 7.88%, all in a low state.
