坡面土壤养分与降雨、径流的相互作用机理及模型

坡地土壤养分流失过程实际上是表层土壤养分与降雨、径流相互作用的过程 ,土壤养分流失的多少主要受相互作用的限制。从分析土壤与降雨、径流相互作用入手 ,分析了土壤养分与降雨、径流相互作用过程及机理 ,并对相互作用模型进行了探讨。

The process of soil nitrogen loss in runoff and sediment is restricted by interaction of soil nutrient with rainfall and runoff. Based on analysis on interaction of soil with rainfall and runoff on slope land, the interacting models and mechanisms of soil nutrient with rainfall and runoff are discussed.
