国内外鱼道研究与建设

本文根据国内外鱼道研究和应用的资料，总结了过坝鱼类的主要种类、鱼道设施的建设和发展状况，其中比较详细地介绍了鱼道结构所包含的主要类型、鱼道流速和池室水力条件的影响因素和目前广泛采用的研究手段，以及在中高水头的坝体中所采取的鱼类过坝措施和鱼类下行问题的研究进展等内容。最后提出了在今后的几十年里我国水利水电工作者需要对鱼道开展研究的建议和主要内容，以期促进生态系统的平衡和物种多样化的保护。

Brief review on research and construction of fish-ways at home and abroad

Based on the data of research and application of the fish-ways at home and abroad, a brief review is given in this paper on the main fish species going through dams and fish-ways construction and development. The main types of fish-ways structures, hydraulic conditions in ponds of fish-ways in terms of flow velocity and relevant factors, as well as dam-passing buildings in dams with moderate and large height are discussed. The research approaches applied today and the research development of fish going downward are summarized. Some suggestions and major aspects that Chinese water engineers would practice in following decades are put forward in order to promote the balance of ecosystem and protection of species diversification.
