Abstrcat Taken the Universal Soil Loss Equation(USLE) as a theory foundation

we used the map algebra method to assess one by one and evaluate synthetically on influence factors of the sensitivity of soil erosion under the support of GIS in Jilin Province. We classified influence of precipitation

soil

topography and vegetation upon factor of soil erosion into five different degrees. As a result

assessment map of each factor was finished. We also drew integrated assessment map of sensitivity of soil erosion by overlapping function with ArcGIS. Through analysis and assessment

it was made clear that possible level

area coverage and spatially distributional pattern of soil erosion sensitivity. Furthermore

the effective countermeasures controlling the soil erosion are discussed. The result will provide the important basis for the partition management of ecology environment

the reasonable use of land resources
