【 摘 要 】

Aiming at maximizing the benefit of water resources utilization and ignoring other functions of the rivers, the hydropower development fundamentally changes the composition, structure and function of river ecosystem, breaks the original ecological balance. The dam has a great impact on the reservoir area and the ecological system of the whole river. The direct-flow power generation project in rivers is a new energy development technology. The results show that the cross-flow turbine with vertical shaft has higher power generation efficiency, and when the flow changes greatly, it can still maintain higher efficiency by the appropriate regulation.
