摘 要:本文以新疆头屯河流域为例,采用滑动平均、Mann-Kendall检验和小波分析等水文统计分析方法,科学分析近64 a新疆头屯河流域径流演变特征。结果表明:头屯河流域径流年际变化小,年内变化大,来水时段与用水时段较为一致,对流域水资源开发利用有利。从趋势、突变分析来看,头屯河流域径流突变点为1965年、1967年和1994年,突变和趋势不显著。从周期分析来看,流域的年径流量周期性明显,第一主周期为40 a,第二和第三主周期分别为11 a和4 a。This article takes the Toutun River Basin in Xinjiang as an example,and uses hydrological statistical analysis methods such as moving average,Mann Kendall test,and wavelet analysis to scientifically analyze the runoff evolution characteristics of the Toutun River Basin in Xinjiang over the past 60 years.The results indicate that the interannual variation of runoff in the Toutun River Basin is small,while the annual variation is large.The inflow period and water usage period are relatively consistent,which is beneficial for the development and utilization of water resources in the basin.From the perspective of trend and mutation analysis,the sudden change points of runoff in the Toutun River Basin were in 1965,1967,and 1994,and the mutation and trend were not significant.From the perspective of cycle analysis,the annual runoff of the basin has a significant periodicity,with the first main cycle being around 40 years,the second and third main cycles being around 11 years and 4 years,respectively.
