摘　　要：水资源在流域生态保护和高质量发展中非常重要,明晰流域径流量变化特征将更有利于水资源的充分利用。黄河流域上游径流量的主要影响因素为气候变化,中游与下游的主要影响因素为人类活动,通过Mann-Kendall突变检验、累计距平和小波分析方法,对黄河流域代表性站点(头道拐、花园口、利津)1960~2020年的径流量数据进行分析,研究了3站60年内的径流序列演变规律。研究结果表明:本文所选用的3个站点的60年内径流量呈现逐渐减少的趋势,表现较明显的是下游径流量变化;3站径流量分别在1985年、1985年和1977年发生突变,并在1995年、1992年和1986年发生显著性减少;此3站的第一主周期是20年、15年、15年。Water resources play an important role in the ecological protection and high-quality development of the basin,and it is more conducive to the full utilization of water resources to clarify the characteristics of runoff change in the basin.The main influencing factors of runoff in the upper reaches of the Yellow River Basin are climate change,and the main influencing factors in the middle reaches and lower reaches are human activities.By means of Mann-Kendall mutation test,cumulative anomaly and wavelet analysis,this paper analyzed the runoff data of representative stations(Toudao Guai,Huayuankou and Lijin)in the Yellow River Basin from 1960 to 2020,and studied the 60-year runoff series evolution law of the three stations.The results show that the runoff of the three representative sites selected in this paper shows a decreasing trend in the past 60 years,and the downstream runoff changes are more obvious;the runoff of three stations suddenly changed in 1985,1985 and 1977 respectively and decreased significantly in 1995,1992 and 1986 respectively;the first main period of the three stations is 20 years,15 years,15 years.
