摘要
介绍了国内外土壤侵蚀预报模型的主要研究成果。所介绍的国外土壤侵蚀预报模型除众所周知的USL E/ RUSL E,WEPP,L ISEM和 EUROSEM外 ,还有浅沟侵蚀预报模型 (EGEM)和切沟侵蚀预报模型。国内的侵蚀预报模型主要有在 GIS支持下的陡坡地包括浅沟侵蚀的坡面侵蚀预报模型、有一定物理成因的坡面侵蚀预报模型和流域预报模型。在总结和评价国内外土壤侵蚀预报模型的基础上 ,提出了中国今后土壤侵蚀预报模型研究的设想。
Main research achievements in soil erosion prediction models in the world are summarized. Besides well-known erosion models, such as USLE/RUSLE, WEPP, LISEM and EUROSEM, ephemeral gully erosion model, gully erosion prediction model are also introduced. Steep hill slope erosion prediction model including shallow gully erosion supported by GIS, the process based hillslope erosion prediction model, and watershed erosion prediction model in China are outlined. Based on summary and assessment on soil erosion prediction model in the world and China, the tentative plan on soil erosion prediction model in China is proposed.
