Research situation and prospect of the soil erosion model

Soil erosion is one of most serious environmental issues.It's very important to build soil erosion model for prediction of soil and water loss,design soil and water conservation measure,and utilize water and land resources.The develop history,research situation,and existing problems for both experiential and process-based soil erosion mode were summarized in this paper.The detailed prospects were given in the aspects of research method,research fields,which need be strengthen,variation of parameters,demonstration for erosion model,and possibility of combining erosion model building with GIS,Remote Sense,and tracer element.The object of this paper was to make the summary of the research experience of soil erosion model and promote the development of soil erosion model in China.
