该文以纸坊沟流域为例，分析了治理小流域侵蚀特征、产沙特征及综合治理减沙效益。结果表明：流域侵蚀强度以中等以下为主，流域产沙主要来源于沟谷地的天然荒坡，流域综合治理具有明显的减沙效益。 Taking Zhifanggou watershed as an example, this paper analyzes the characteristics of erosion, sediment yield and comprehensive benefits of sand control in small watershed. The results show that the erosion intensity in the basin is dominated by below average, and the sediment yield in the basin mainly comes from the natural wasteland in the gully valley. The comprehensive management of the river basin has obvious sediment reduction benefits.
