摘　　要：仿自然过鱼通道是具有自然特征的旁路水道,它作为过鱼设施,不仅可减缓大坝、水闸、堰等水工建筑物对河流产生的阻隔影响,还在一定程度上改善了鱼类适宜生境。介绍了仿自然过鱼通道的特点和分类,系统总结了仿自然过鱼通道的设计要点,包括仿自然过鱼通道设计的前期工作、鱼道布置、水力学设计、诱鱼补水系统等关键设计原则与标准,并对鱼道的建设和发展提出了相关建议,可为今后仿自然过鱼通道的设计和研究提供参考。A nature - sinulating fishway is an artificial by - pass waterway with natural features for fishes passing through the dan. The fish passing facility nay not only nitigate the negative influences on rivers＆#39; ecology induced by the construction of dans,locks,weirs and other hydraulic structures,but also inprove the habitat for fishes. The paper introduces the features and categorization of nature - sinulating fish passages. The critical points in design of such passages are systenatically sunnarized, including key principles and standards of pre - stage preparation,layout,hydraulic design and fish - luring and water supplenent systen. Finally,the corresponding suggestions on construction and developnent of fish passage are proposed.
