[Objective] Through evaluating the impact factors of soil erosion sensitivity for the Cixi City of Zhejiang City, references for conducting the environmental functional zoning and the layout of water conservation measure were expected to be provided. [Methods] According to the USLE model, rainfall erosion force, soil texture, vegetation cover and terrain fluctuation were selected to construct sensitivity evaluation system of soil erosion. Moreover, GIS was employed to analyze soil erosion sensitivity. [Results] Results showed a semicircle structure in the spatial distribution pattern of soil erosion sensitivity in Cixi City. The area of slight sensitivity was 733.05 km², accounting for a high percentage of 75.7%, which was widely distributed in the villages and towns of plain area. The insensitive part located in the offshore area of tidal flat. The areas of extreme sensitive, high sensitive and moderate sensitive were mainly distributed in the hill and mountain regions of the southern part of Cixi City. [Conclusion] The results of sensitivity evaluation were in accord with the spatial distribution of soil water loss, indicating that more attentions should be paid to the conservation of soil and water.
