以6条小流域的水土保持工程措施为研究对象,对蓄水保土效益进行了分析,同时对减弱地表径流、削减洪峰流量的效果等进行了探讨。研究表明,经综合治理的小流域与未经综合治理的小流域相比,其平均土壤流失量此未经综合治理的小流域平均土壤流失量少13.73%,其平均径流系数较未经综合治理的小流域低31％。此外,其完善的水保措施在减弱地表径流、削减洪峰等方面发挥的作用也大于未经综合治理的小流域。
Based on the six soil and water conservation measures in six small watersheds, the benefits of water and soil conservation were analyzed. At the same time, the effects of reducing surface runoff and reducing peak flow were discussed. The results show that compared with the small watershed without comprehensive treatment, the average soil loss in the comprehensively managed small watershed is 13.73% less than that in the small watershed without comprehensive control, and the average runoff coefficient is lower than that without comprehensive management The small watershed is 31% lower. In addition, its comprehensive water conservation measures play a greater role in reducing surface runoff and reducing flood peaks than in small watersheds that have not been comprehensively managed.
