林地地表径流的研究

Study on the surface flow of forest

赣西北山地林区五种不同立地类型地表径流研究结果表明,林地具有良好的入渗性能,地表径流只占林外降雨的1—5％。秩相关分析和典型相关分析表明,林地地表径流年内具有Rs,Rsat,Rr三种不同的产流机制,且与降雨特性关系密切。

The surface runoff of forest in five different living conditions in northwestern Jiangxi Province is studied,the result shows that the forest land could be infiltrated well and the runoff is only 1—5% of rainfall out of forest.Both rank and typical correlation analyse indicate that the runoff in the forest has three kinds of mechanisms of flow producing, afrected with rainfall character closely.
