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2 765万m3和4 250万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,需要采取最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。
Based on the ecological characteristics of the Biliuhe Basin, the calculation method of river ecological water demand is introduced in this paper. This method is applied in the profit regulation of the Biliuhe Reservoir in order to determine the river ecological water demand based on the ecological objectives. The results show that the basic and improved ecological water supply in the lower reaches of the Biliuhe reservoir are 27.65 million cubic meters and 42.5 million cubic meters, respectively. In order to protect and improve the river ecological environment and facilitate the sustainable utilization of water resources in the Biliuhe basin, the strictest water management system and the development and utilization of non-conventional water resources need to be implemented, as well as the water diversion project and river-reservoir connectivity project.
