摘　　要：枯水期珠江河口区咸潮上溯给珠江三角洲城市的供水安全带来极大威胁,上游水库群联合调水压咸是应对咸潮的有效措施。以西江、北江骨干水资源调配水库为研究对象,以满足思贤滘断面“压咸补淡”流量为目标,建立了西江、北江骨干水库群联合调度模型,研究不同来水情况下的骨干水库群联合调度方案。研究成果对于缓解珠江三角洲“旱上加咸”带来的供水保障问题具有重要意义,可为后续实时优化调度提供参考。Saltwater intrusion in the Pearl River estuary during dry season seriously affects the freshwater supply security of cities in the Pearl River Delta.The joint regulation of upstream reservoirs to increase downstream flow is one of the effective measures to deal with saltwater intrusion.To meet the demand for the discharge of Sixianjiao section for suppressing saltwater and replenshing freshwater,a regulation model for the key reservoirs in the Xijiang and Beijiang River basins was established to study the water replenishment strategy under different discharge conditions.The results have great significance for alleviating freshwater supply problem caused by drought and saltwater intrusion in the Pearl River Delta,and can provide reference for realtime optimal dispatch in the future.
