王河沟小流域位于博爱县寨豁乡北部,流域总面积32.12 km~2,水土流失面积26.44 km~2,该流域土壤侵蚀类型为水力侵蚀,以面蚀和浅沟蚀为主,水土流失严重。针对王河沟小流域水土保持存在的主要问题,将该流域列入博爱县2009-2011年太行山区水土保持小流域综合治理工程内,综合治理面积16.45 km~2。其中工程治理措施面积5.97 km~2,生态修复措施面积10.48 km~2。工程总投资506万元。从已治理的流域来看,王河沟小流域生态环境正在逐步恢复,综合治理效果显著。通过王河沟小流域综合治理实践,探索博爱县太行山区水土保持小流域综合治理新思路。
The Wanghegou small watershed is located in the northern part of Zhai County, Bo’ai County, with a total drainage area of 32.12 km ~ 2 and an area of 26.44 km ~ 2. The soil erosion type is water erosion, which is dominated by surface erosion and shallow ditches, with serious soil erosion . Aiming at the main problems of soil and water conservation in Wanghegou small watershed, the watershed was included in the Comprehensive Control Project of Soil and Water Conservation Small Watershed of Taihang Mountain from 2009 to 2011 in Bo’ai County, with a comprehensive control area of 16.45 km ~ 2. Among them, the area of engineering measures is 5.97 km ~ 2 and the area of ecological restoration measures is 10.48 km ~ 2. The total investment of 5.06 million yuan. From the management of the basin, the ecological environment of Wanghegou small watershed is gradually restored, and the comprehensive treatment results are remarkable. Through the practice of comprehensive management of Wanghegou watershed, a new idea of comprehensive harnessing of small watersheds for soil and water conservation in Taihang Mountainous area of Bo’ai County was explored.
