【摘要】：研究湟水流域水生态现状和保护与修复措施,加强湟水流域水生态保护,维持黄河尤其是黄河上游流域及青藏高原和黄土高原-川滇生态屏障生态安全。湟水干流、大通河梯级开发集中,河流纵向连通性遭到严重破坏,且大部分水电站是引水式小水电站,枯水期水电站下游河道脱流现象严重,河流水流连续性及横向连通性遭到破坏,河流生态功能严重下降。根据国家及黄河流域对湟水流域生态保护定位及要求,在湟水流域水生态状况评价及问题识别的基础上,明确各区域(河段)水生态保护目标,提出了湟水上中下游水生态保护与修复总体布局、重要断面生态需水指标及保障措施和重要湿地、重要鱼类栖息地等保护与修复措施体系。
[Abstract]:The present situation of water ecology and the measures of protection and restoration in Huangshui basin are studied in order to strengthen water ecological protection in Huangshui basin and maintain ecological security of ecological barrier of Yellow River, especially the upper reaches of Yellow River, Qinghai-Xizang Plateau and Loess Plate- Sichuan-Yunnan ecological barrier. In the main stream of Huangshui River, the cascade development of Datong River is concentrated, the longitudinal connectivity of the river is seriously destroyed, and most of the hydropower stations are small hydropower stations of diversion type. The continuity and lateral connectivity of river flow were destroyed, and the ecological function of river was seriously decreased. According to the orientation and requirements of the national and Yellow River basins for the ecological protection of the Huangshui River Basin, on the basis of the evaluation and identification of the water ecological status of the Huangshui River Basin, the water ecological protection objectives of each region (reach) are defined. The general arrangement of ecological protection and restoration of water in the upper middle and lower reaches of Huangshui River, the ecological water demand index and protection measures of important section, the important wetland and the important fish habitat protection and restoration measures are put forward.
