摘要
基于汉北河2个典型断面(天门断面、汉北河民乐闸断面)的鱼类调查资料与长时间序列实测数据(水深、流量、断面等),运用流速法(最小、平均、最大)进行生态需水量计算。基于生径比概念,对流速法计算的生态需水计算结果进行评价,结果表明,汉北河流域目前水流量可较好地满足最小生态需水的需求,对于适宜生态需水只能部分月份满足。
Based on the fish survey data and long time series measured data （such as water depth, flow rate, section, etc.） of two typical sections （such as Tianmen section and Minyue gate section） in Hanbei River, the ecological water demand was calculated by velocity method （minimum, average, maximum）. Based on the concept of ratio of eco-water demands to stream flow, the calculation results of ecological water demand calculated by velocity method were evaluated. The results showed that the current water flow in the Hanhei river basin could well satisfy the needs of the minimum ecological water demand, but could only satisfy partial months for the appropriate ecological water demand.
