流域植被对径流调节作用的实验研究

Experimental Study on Influence of Watershed Vegetation on Runoff

根据河北省邢台市西部山区两个小流域实验站的水文监测资料,研究了不同流域内的不同植被对径流的影响。分析了流域植被对径流的年内分配、径流系数、削减洪峰以及枯季径流量等的影响。结果表明,流域植被对涵养水源、调节径流量、增大枯季径流量起到重要作用。

According to the observed data from two small watershed experimental stations in the western mountainous area of Xingtai City in Hebei Province,a study was made on the influence of different vegetation on runoff in various watersheds,including the effects on annual distribution of runoff,runoff coefficients,attenuation of flood wave and low water flow.The results show that the watershed vegetation plays an important role water resources self-control,runoff regulation and low water flow increasing.
