Effects of soil and water conservation of vegetation measures in the middle Yellow River
摘要
Abstract
Afforestation,grass planting,and natural restoration are typical soil and water conservation measures(SWCMs)in the middle Yellow River.Analyzing these SWCMs' water and sediment regulating effects is of great sig-nificance for understanding the mechanisms of runoff and the future situation of water and sediment in the middle Yellow River.This article analyzed 1165 relevant literature and compiled 1089 datasets containing three indicators:surface runoff modulus,sediment yield modulus,and average infiltration rate.It then conducted a quantitative analy-sis of the water and sediment regulating effects of these SWCMs,as well as the influence of terrain slope and rainfall intensity on these effects.The results indicate that the effects of soil and water conservation of afforestation and grass planting increased with the increase of vegetation coverage,but decreased with the increase of terrain slope and rain-fall intensity,especially when the rainfall intensity was more than 120 mm/h.The effect of soil water storage of natu-ral restoration increased with the increase of restoration years,and the effects of water and sediment reduction were relatively stable when the restoration years are between 30 and 60 years.The effective values of these SWCMs are pro-posed to provide parameter support for numerical simulation.It is recommended that the vegetation cover of grass planting should be controlled within 60％and afforestation should be controlled within 60％—70％.关键词
