摘 要: 研究河川径流的时序变化特征对径流水资源的合理开发与可持续利用具有重要意义。根据奎屯河流域各河流水文站1959年至2006年的径流量资料,采用多种径流统计分析方法对流域内各河流年内和年际变化进行分析。结果表明:奎屯河流域内各河流年内分配极不均匀,集中度在56%~60%之间;通过Kendall检验也表明各河流径流的年际变化呈现显著增加趋势。且径流的年际变化变差系数均在0.128~0.156之间,说明奎屯河流域河流径流量年际变化很小。因此可以认为奎屯河流域各河流径流年际变化呈现稳定递增,这也与近年来新疆气候变化相吻合。
关 键 词: 水利工程基础科学;径流;年内分配;年际变化;奎屯河流域

Abstract: Studying on the temporal variation characteristics of river runoff is of great significance for water resources development and sustainable use. According to the runoff data of the hydrologic stations in Kuitun River basin from 1959 to 2006, this paper uses a variety of statistical analysis methods to analyze the intraannual and inter-annual variation of the rivers in the basin. The results show that the annual distribution of Kuitun River basin is uneven, and the concentration degree is between 56% and 60%; according to Kendall test, the inter-annual variation of the river runoff shows an upward trend. And the variation coefficient of the inter-annual change is between 0.128 and 0.156. It indicates that the inter-annual variation of runoff is small in Kuitun River basin. Therefore, it can be considered that the inter-annual variation of runoff in Kuitun River basin has increased stably. This is also coincided with climate change in Xinjiang province in recent years.
Key words: hydraulic engineering basic science; runoff; annual distribution; annual variation; Kuitun River basin
