Soil erosion is a global environment problem. It reduces the production ability of soil and the quality of water, then leads to the soil sediment and increases the occurrence possibility of flood. With the worse condition of the worldwide soil erosion, and the prominence of the problem of soil and water lost,the research of soil erosion becomes more embedded. However, at the present time, almost all the jobs in this field are limited to such an aspect as the model amendment and the selection of its correlative factors and lacks for a good interface to complete the analysis and the visualization of model factors. Utilizing the GIS technique adequately, this experiment has established a network model based on USLE and devised a friendly interface to solve this problem. The experiment indicates that this model not only represents the research results adequately by a good interface, but also gives a good indication to improve the soil erode model by utilizing the correlative tools of GIS.
