复合式驱鱼系统在水电工程中的应用研究

摘要

The operation of water diversion system, power generation system and flow discharge structure of hydropower pro-jects will exert adverse impact on fish safety. A new composite fish driving system that has slight damage to fishes is developed on the basis of summarizing various fish driving measures at home and abroad. The juvenile grass carp is taken as the research ob-ject, and an experiment for fish driving factors verification is carried out. The experiment result indicates that the fish driving sys-tem is flexible and efficient and conducive to ecological protection, providing a new conception for research, design and practical application of other composite fish driving systems.%水电工程的引水发电过流系统及泄水建筑物工作时会威胁鱼类安全。为规避风险，在综述国内外各种导鱼措施的基础上，发明了一种对鱼类损伤较小且具有主动性的复合式驱鱼系统，并以草鱼幼鱼为研究对象进行了部分驱鱼因子的试验验证。结果表明，该系统灵活高效，且利于生态保护，给水电工程中复合式驱鱼系统的研究设计及实际应用提供了思路。
