大藤峡水利枢纽工程设计中的水生态优化措施

针对水利水电工程对环境的影响和大藤峡水利枢纽工程所在江段的水生生态敏感性,探讨大藤峡水利枢纽工程设计中的水生态优化措施:优化运行水位;采取保护鱼类、优化施工方案的多种水生态保护措施;实施生态调度。分析这些水生态保护措施的可行性及有效性,认为这些措施技术上可行,可有效减缓水利工程对鱼类产卵场及鱼类资源的影响。

Measures for aquatic ecological optimization in design of Datengxia Water Project

With consideration of the influence of hydraulic and hydro-power projects on aquatic environments and the sensitivity of the aquatic ecosystem in the river reach of the Datengxia Water Project, measures for aquatic ecological optimization in the design of the Datengxia Water Project are discussed in this paper. These measures include optimizing the operating water level, protecting the aquatic ecosystem through fish conservation and optimization of construction schemes, and aquatic ecological operation. The feasibility and effectiveness of the measures are analyzed. The results show that the measures are technically applicable and can effectively reduce the influence of water projects on fish spawning sites and fish resources.
