摘　　要：常规的鱼道设计及研究大多侧重于其内部结构和水流条件方面,缺少对鱼类生活习性及洄游规律等方面的认识,从而忽略了鱼道进口布置的重要性。而实际上鱼类能否较快发现和进入鱼道进口是鱼道设计的关键因素之一。以楠溪江供水工程鱼道设计为例,通过物理模型试验,对当地鱼类生活习性、建筑物布置特点以及各工况水流条件进行了观测分析,提出将鱼道进口与电站尾水渠相结合的布置方式,并对其可行性进行了论证,该布置方式对研究鱼道进口具有较大的参考意义。The ordinary fishway design and research mostly put emphasis on internal structure and flow conditions,with poor recognition of the habits and migration laws of fish.So the importance of the layout of fishway entrance is neglected.Actually,whether the fish can quickly find and enter into the fishway is a key factor of design.Taking the case of fishway in Nanxi River,we analyze the behaviours of the local fish,the characteristics of structure arrangement and the flow conditions by physical model;thus propose to put the fishway entrance together with the tailrace of a hydropower station and vertify its feasibility.This arrangement has great significance to the study of fishway.
