摘　　要：本文通过运用多尺度熵分析方法,对石羊河流域4个典型盆地6个观测井站逐日平均地下水位序列复杂程度进行分析,结果表明:流域治理措施实施以来,2007—2015年(H1)地下水位缓慢下降,2016—2018年(H2)地下水位逐步上升;武威、民勤、永昌盆地各时间尺度上H1的复杂性高于H2;昌宁盆地在较小的时间尺度上(τ<11天),H2的复杂性略高于H1,而在较大的时间尺度上(τ>14天),H2的复杂性则略低于H1。研究成果对提高流域水资源管理具有一定的现实意义。In this paper,the complexity of daily average groundwater level series of 6 observation stations in 4 typical basins of Shiyang River basin is analyzed by using multi-scale entropy analysis method.The results show that since the implementation of watershed control measures,the groundwater level has decreased slowly from 2007—2015(H1),and gradually increased from 2016—2018(H2).The complexity of H1 is higher than that of H2 in Wuwei,Minqin and Yongchang basins on various time scales.On a smaller time scale(τ<11 days),the complexity of H2 is slightly higher than that of H1,while on a larger time scale(τ>14 days),the complexity of H2 is slightly lower than that of H1.The research results have certain practical significance for improving water resources management in river basins.
