摘　　要：利用赣江下游外洲水文站1950-2017年实测逐日流量资料及流域内5个气象站点1953—2017年逐日降水数据,采用Mann-Kendall检验法和小波分析等方法,对赣江干流下游段枯水极值流量的变化特征、趋势性、突变性及周期性进行了分析,并探讨了枯水极值流量变化的原因。Based on daily runoff data in the Waizhou hydrological station from 1950 to 2017 and daily precipitation data in 5 meteorological stations from 1953 to 2017 in Ganjiang River basin,the characteristics of extreme low flow was analyzed by using the non-parametric Mann-Kendall test and wavelet analysis,and the causes of extreme low runoff changes were discussed herein as well.
