为更好地对河流水电开发后的鱼类进行保护,探讨中型山区河流水电站下游的鱼类生态需水量计算.参照大型河流鱼类水力生境参数标准,根据中型山区河流的特点,得到中型山区河流鱼类水力生境参数的参考标准.选取有代表性的四川中型山区河流杂谷脑河进行鱼类生境原型观测,原型观测结果证实了该参考标准能够满足杂谷脑河鱼类对生境的实际需求.基于所得到的参考标准,应用生态水力学法对杂谷脑河红叶二级、理县以及甘堡3座电站减水河段的鱼类生态需水量进行计算分析,得到3座电站的生态需水量推荐值.通过分析可知,所得到的生态需水量推荐值占年均天然流量以及设计引用流量的比例都不高,在3座电站的运行实践中,具有可操作性.

@@@@To protect fishes after hydropower development on rivers,calculation on the ecological water requirements of fishes in downstream reach of hydropower station in medium mountainous rivers was discussed. With reference to the standard of hydraulic habitat parameter for fishes in large rivers,and according to the characteristics of medium mountainous rivers,the reference standard of hydraulic habitat parameters for fishes in medium mountainous rivers were obtained. The representative medium mountainous river, Zagunao River in Sichuan province, was selected for the prototype observation of fish habitat. The results confirm that this reference standard can meet the actual requirements of fish habitat in the Zagunao River. Based on the obtained reference standards,the ecological hydraulic method was used to calculate and analyze the ecological demand of fishes in the water reducing reaches of Hongye Ⅱ,Lixian and Ganbao hydropower stations on Zagunao River,and the recommended values of ecological water demand of the three hydropower stations were obtained. The analysis results show that the proportion of the obtained recommended values of ecological water requirements in the annual average natural flow are not high. These values have operability in the operation of the three power stations.
