土壤侵蚀模型研究现状与展望

Research situation and prospect of the soil erosion model

土壤侵蚀已成为极为严峻的环境问题之一 ,对它进行准确的预报具有重要的实践意义。本文对国内外土壤侵蚀模型的研究现状进行了详细的回顾 ,并对我国土壤侵蚀模型研究中相对薄弱的环节进行了深入的分析。旨在借鉴国外研究经验 ,促进我国土壤侵蚀模型研究的进展。

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.
