摘要
从分析无定河流域不同时段水土保持措施配置入手,以减沙效益为研究目标,探讨了水土保持措施优化配置问题。分析认为:水土保持措施配置与减沙效益是密切相关的,淤地坝在水土保持措施配置中应占有合理比例,无定河流域坝地配置比例应大于3%;坡面治理措施配置中需进一步加大封禁治理比例。
The paper approaches the optimized configuration of soil and water conservation measures from the configuration of soil and water conservation measures in different time intervals of the Wuding River basin and by taking the benefits of sediment reduction as the objective of study.It considers through analysis that the configuration of soil and water conservation measures is closely related to the benefits of sediment reduction,warping dams should make up rational proportion in the configuration of soil and water conservation measures and the proportion of warping dams in the Wuding River basin should be greater than 3% and;the proportion of closing and prohibiting in treatment measures should be further increased in the configuration of slope control measures.
