三道沟河干流梯级开发形成的脱水段对生态环境的影响

Effect of dewatering section formed in cascade development on ecological environment in mainstream of Sandaogou river

以三道沟河干流开发为例,主要探讨脱水段对周边居民生活及生态环境的影响,提出较合理的解决方案。通过分析研究八级水电站、十三级贾家营子二级水电站对居民生活及周边生态产生影响,提出了技术可行,经济合理的备选方案。本成果可为同类工程的开发提供参考。

Taking the hydropower development Sandaogou river mainstream for example, the paper ex- plored the impact of dewatering section on the living of local residents and the surrounding ecological en- vironment, and finally proposed a more reasonable program. Through analyzing the influence of eighth grade hydropower station and thirteenth Jiajiayingzi second grade hydropower station on the living of local residents and the surrounding ecological environment, it presented a technical feasible, economic rational alternative program. The result can provide reference for the development of similar projects.
