中文摘要:
      根据碧流河流域生态特征,分析了适合该流域的河道生态需水计算方法,应用于碧流河水库兴利调度,并以生态目标为基础,确定下游河道的生态需水量。结果表明:碧流河水库下游河道生态环境基本供水量及改善供水量分别需要2765万m3和4250万m3。为了保护和改善河流生态环境,促进流域水资源可持续利用,需要采取严格的用水管理制度,加大非常规水源的开发利用力度,并结合调水工程以及河库连通工程等相关措施。
英文摘要:
      Based on ecological characteristics of Biliuhe Basin, The calculation method of river ecological water requirement is introduced in this paper. This method is applied in profit regulation of Biliuhe Reservoir in order to determine the river ecological water demand. The results show that the basic and improved ecological water supply of Biliuhe reservoir is 27.65 million cubic meters and 42.5 million cubic meters, respectively. The river ecological environment will be significantly improved with the implementation of the strictest water management system and the development and utilization of non-conventional water resources, as well as the implementation of the water diversion project and river-reservoir connectivity project.
