摘 要:采用吸附态非点源污染负荷模型对水土保持治理典型区域绥德韭园沟流域水保措施实施各阶段的污染物流失量进行定量计算。结果表明,水土保持措施对氮、磷及有机质有较好的拦截作用,在一定程度上可控制非点源污染并改善水环境。Based on the analysis of the effects of soil and water conservation on water environment, the paper takes the Jiuynangou Catchment which is the typical area of soil and water conservation comprehensive management as a case and quantitatively studies the effect of soil and water conservation on water environment by using absorbed non-point source pollution model. The research results indicated that soil and water conservation which brings active effects on the water environment in the catchment has played a notable role in intercepting TP, TN and organic matter. The retention efficiency becomes more and more obvious with the gradual improvement of soil and water conservation.
