阿克苏河多时间尺度干支流径流演变规律分析
Analysis of Runoff Evolution Patterns on Multiple Timescales in the Main and Tributary Streams of the Aksu River
摘要
Abstract
In view of the issues existing in the current research on runoff evolution in the Aksu River basin,such as a single time-scale and insufficient consideration of the sensitivity of sequence length,a variety of methods such as Mann-Kendall trend test,Theil-Sen Median trend estimation,Pettitt mutation test and wavelet analysis were adopted to systematically study the runoff evolution laws of the main and tributary streams in this basin at different time scales such as inter-annual,intra-annual and flood events.The results show that the annual runoff of the Taushgan River,Aksu New River and Tailan River increase gradually,while the change of the Kumarak River is not obvious.The periodic oscillation of the four rivers is the most obvious on the 35-year,55-year,35-year and 55-year timescale,and the corresponding periods are 21-23 years,32-35 years,19-25 years and 36 years respectively.The annual distribution of runoff in the Aksu River basin is uneven,the runoff is larger in summer and autumn,and smaller in winter and spring,and the concentrated period is from June to August.The annual maximum flood peak discharge of the mainstream and tributaries fluctuate greatly,mainly concentrate in July and August.The key periods for flood control are July-September,April-August,July-August and July respectively.The tendency,mutability and periodicity analysis results of the runoff in the Aksu River watershed are all affected by the length of time series.关键词
