摘要
分析了森林植被不同层次对降水影响所引起的径流量、径流能量和径流的挟沙能力及其减小的效应。研究得出 :植被保持水土主要是由其不层次同时连续消耗径流量所致 ;不同的效应叠加使土壤侵蚀量急剧减小 。
Soil and water conservation function of forest vegetation has been explained through analytical effects of vegetation different layers on rainfall effect.The result of reduction of run off amount and run off energy and runoff carrying sediment and vegetation improving soil to make a great role of soil and water conservation because of vegetation increasing resistant soil erosion.The research point out soil and water conservation function of vegetation is due to using out runoff amount continual by vegetation different layers,accumulation effects of vegetation different layers lead quickly reduction of soil erosion amount as to realize bring function of vegetation soil and water conservation into full play.
