Abstract:: Shiyang River basin was chose as the study area, on the basis of remote sensing data sources, ArcGIS zonal statistical method was adopted to improve the land ecological sensitivity evaluation through building the water loss, soil erosion, soil salinization, desertification and soil biodiversity as quantitative evaluation indexes. The land sensitivity characteristic and influence factors of Shiyang River basin were analyzed using raster overlay analysis. The results show that the extremely and highly sensitive area of the basin accounts for 74.68% of total area; the low sensitivity and insensitivity area accounts for 10.59% and 0.88% of total area, respectively. Finally, in view of the characteristics of land ecological sensitivity division of Shiyang River basin, some policies are proposed according to the research results and other materials in order to provide some scientific evidences for ecological management of Shiyang River basin in the future.
