鉴于传统鱼道适用范围窄、引鱼措施不完善、过鱼种类单一以及鱼道淤沙问题严重等缺陷，提出了一种流速可控式新型生态鱼道的概念设计模型，并结合大型通用流体力学计算软件Fluent对该新型生态鱼道进行数值模拟仿真研究。结果表明：通过调整鱼道中可旋转式隔板与边壁的夹角角度，从而改变鱼道中水流的流速大小，进而满足不同洄游鱼类对不同水流流速的适应要求。

In order to improve the defects of traditional fishway,such as the narrow scope,inadequate mea?sures on attracting fish,single fish species,serious siltation problems and so on,a conceptual design about eco?fish?way by controlling velocity of flow was proposed in this paper. The numerical simulation was carried out with a gen?eral CFD software Fluent. The results show that the flow velocity in the fishway can be changed to meet the require?ments of different migratory fish by adjusting the angle between rotatable clapboards and side walls in fishway.
