森林植被对流域产汇流机制的影响效应分析

通过对城西径流实验站的产汇流特性分析,得出由于森林植被的急剧减少而引起的流域产汇流特性变化,论述了森林植被对涵蓄水源以及径流的调节作用,要植树造林,恢复森林植被,实现生态环境的良性循环.

Analysis of the Watershed Runoff Yield and Concentration on the Variation of the Forest Cover

This paper introduces briefly the characteristics of runoff yield and concentration of Chengxi Runoff Experimental Basin. The main conclusion is that rapid decrease of forest and vegetation cover is the key reason for its hydrological characteristic change. It expounds that plants can conserve, stores water and regulate runoff. More attention should be paid to the afforestation and forest cover reservation in order to achieve the well cycle of the ecological environment.
