国内土壤侵蚀预报模型研究进展

Review of Research Progress in Soil Erosion Prediction Model

土壤侵蚀预报模型是定量预测、预报土壤侵蚀量的重要工具,对水土保持及生态环境建设具有重大的意义。本文对国内土壤侵蚀预报模型研究进展作了综述,重点介绍了国内土壤侵蚀预报模型的发展历程、USLE和以其为蓝本的侵蚀预报模型、流域侵蚀产沙经验模型和我国关于生产建设项目侵蚀量预测的模型等。对侵蚀预报模型的研究进展进行总结并指出生产建设项目侵蚀预报模型的研究具有紧迫性和艰难性。

Soil Erosion Prediction Models are important tools for predicting soil erosion quantitativly and have great significance for soil and water conservation and ecological environment construction. This article made a summarize of soil erosion prediction model on domestic and foreign. It focused on the history of domestic soil erosion prediction models,the universal soil loss equation and other erosion prediction models based on it. It also introduced the erosion and sediment yield models in watershed scales and soil erosion prediction on product and construction projects in China. It summarized the progress of erosion prediction models research. It showed the urgency and difficulty of the research on the soil erosion prediction models of production and construction projects.
