土壤侵蚀是全球性的严重环境问题。揭示土壤侵蚀过程,建立土壤侵蚀模型将为土地合理利用规划、水土保持措施优化配置、水土流失监测及水土保持减水减沙效益评价等生产实践提供重要科学依据和技术工具。土壤侵蚀预报模型按建模方法可分为经验模型与物理模型等,其中,经验模型主要
Soil erosion is a serious global environmental problem. Revealing the process of soil erosion and establishing a model of soil erosion will provide important scientific basis and technical tools for the rational utilization of land planning, optimal allocation of soil and water conservation measures, monitoring of soil and water loss and evaluation of benefits of water and sediment reduction by soil and water conservation. Soil erosion prediction model can be divided into empirical models and physical models according to modeling methods. Among them, empirical models are mainly
