摘　　要：本研究对大清河流域主要河流与湿地生态水量进行了计算,合计生态需水量6.7亿m3。现状山区河段生态水量基本满足,平原河段生态水量满足状况较差,湿地生态水量均不满足。对生态不满足的9个平原河段和3个湿地进行水量保障分析,在新增本地地表水对生态用水的供水能力前提下,合理利用再生水和外调水,并结合当地大水网建设,保障大清河流域生态水量。In this study,the ecological water demand of the main rivers and wetlands in the Daqing River Basin were calculated.The total ecological water demand was 670 million m3.In the present situation,the ecological water quantity of mountain river section is basically satisfied,while that of plain reach is poor and the quality of wetland is unsatisfactory.Based on the analysis of water quality guarantee of nine plain river sections and three wetlands with unsatisfactory ecology,the ecological water quantity of Daqing River Basin should be guaranteed by rational utilization of reclaimed water and water diversion from outside under the premise of increasing the water supply capacity of local surface water to ecological water.
