鱼道规划设计与建设的生态学方法研究

Study on Designing and Building of Fishways by Using Ecological Way

由于我国所建鱼道目前普遍存在有水无鱼、鱼道淤塞的现象,鱼道的利用率不高,较多水利工程对设计及修建鱼道采取弃而不用的态度。通过对水利工程中河道的阻隔作用的分析,提出修建鱼道的必要性。并运用生态学观点对鱼道规划设计与建设的现状进行分析,找出存在的问题,提出建议,并对鱼道的发展前景进行展望。

Recently the built-up fishways are generally silted up and fish can not move through the fishways,the use of the fishways is not effective.So,the fishways are abandoned by water conservancy workers in the process of the design and construction of hydraulic engineerings.In the article,the necessary of building the fishways is discussed by researching the built-up dam＇s barrier effect to the natural river.By means of analyzing the current situation of the design and construction of fishways by using the ecological way,the existent problems are found out,and the suggestions and development prospect of the fishway are put forward.
