摘　　要：珠江自2006年开始对流域5座骨干水库实施调度以保证珠海、澳门等珠江三角洲地区的供水安全。西江流域上的天生桥一级水电站、龙滩水电站、百色水利枢纽3座水库是枯季水量调度的骨干水库。对2006年以来3座骨干水库的枯季调水量以及西江控制站梧州水文站的枯季流量进行了分析总结,西江的调度效果显著。以西江控制断面梧州水文站流量大于1800 m3/作为指标,逆向推求2019-2020年调度的可能蓄水量,经综合分析,2019年汛末的蓄水情况对今冬明春的流域调水形势比较有利。该分析将为今后的西江枯季水量调度提供参考,具有实际应用价值。Five key reservoirs within the Pearl River basin have been regulated jointly since 2006 to guarantee the water supply safety of Pearl River Delta including Zhuhai and Macao.Tianshengqiao-Ⅰ Hydropower Station,Longtan Hydropower Station and Baise Multipurpose Dam Project in Xijiang River basin are key reservoirs for dry season water regulating.The authors analyze and summarize the regulated water quantity of three reservoirs since 2006 and the dry season river flow measured by Wuzhou Hydrological Station,the control station of Xijiang River.The water regulating effect is significant.With the river flow at Wuzhou Hydrological Station exceeding 1800 m^3/s as control index,the possible regulating water storage of 2019-2020 is calculated.Based on comprehensive analysis,water storage by the end of flood season of 2019 and the water regulating situation in winter of 2019 and spring of 2020 is favorable.The results of analysis have practical application value and provide reference for dry season water regulating of Xijiang River in the future。
