摘　　要：本文基于黑河莺落峡水文站、正义峡水文站长系列水文资料,采用Q_(P)法、最枯月平均流量法计算了两处水文站断面的最小生态流量,并用Tennant法对计算结果进行评价。研究结果表明,莺落峡站断面用Q_(P)法和最枯月平均流量法得到的最小生态流量值分别为11.06m^(3)/s和13.26m^(3)/s,一年内最小生态流量可以满足生物栖息地需水要求;正义峡站断面用Q_(P)法和最枯月平均流量法得到的最小生态流量值分别为0.37m^(3)/s和1.63m^(3)/s,一年中5月的最小生态流量能够支撑大部分水生生物的生存栖息地。Based on the long series hydrological data of Yingluoxia Hydrological Station and Zhengyixia Hydrological Station in Heihe River,the minimum ecological flow of the two hydrological stations was calculated by Q_(P) method and average flow method in the driest month,and the results were evaluated by Tennant method.The results show that the minimum ecological flow values obtained by Q_(P) method and average flow method in the driest month at Yingluoxia Station are 11.06m^(3)/s and 13.26m^(3)/s,respectively,and the minimum ecological flow in one year can meet the water demand of biological habitat.The minimum ecological flow values obtained by Q_(P) method and average flow method in the driest month at Zhengyixia Station section are 0.37m^(3)/s and 1.63m3/s,respectively.The minimum ecological flow in May can support the living habitat of most aquatic organisms in one year.
