三条川骨干坝位于黄土丘陵沟壑区第Ⅲ副区,该区沟壑纵横,地形破碎,水土流失严重,生态环境脆弱。为治理水土流失,发展水浇地面积,解决控制区内群众的交通问题及人畜饮水问题,建设三条川骨干坝工程是十分必要的。基于此,本研究详细分析该工程的建设效益,为相关工程的开展提供依据。 The Three Rivers backbone dams are located in the third sub-district of the loess hilly and gully area. The area is ravaged and the terrain is fragmented with serious soil erosion and the ecological environment is fragile. In order to control soil and water loss, develop irrigated land, and solve the traffic problems of people in the controlled areas as well as drinking water for people and livestock, it is necessary to build three key dam projects. Based on this, this study analyzes in detail the construction efficiency of the project and provides the basis for the development of related projects.
