基于塔里木河源流区6个水文站1957年-2008年的实测径流资料，运用非参数检验、小波分析等方法探讨了径流量年内变化特征。结果表明：塔里木河源流区月径流量以及丰水期、枯水期径流量以显著增加趋势为主；源流山区径流量集中度指数在协合拉水文站有轻微增加，而在其他5个水文站皆表现减少趋势；径流量集中度指数的显著周期集中在3~8 a。以上研究结果可为实现该流域水资源的合理配置提供理论依据。
基于塔裏木河源流區6箇水文站1957年-2008年的實測徑流資料，運用非參數檢驗、小波分析等方法探討瞭徑流量年內變化特徵。結果錶明：塔裏木河源流區月徑流量以及豐水期、枯水期徑流量以顯著增加趨勢為主；源流山區徑流量集中度指數在協閤拉水文站有輕微增加，而在其他5箇水文站皆錶現減少趨勢；徑流量集中度指數的顯著週期集中在3~8 a。以上研究結果可為實現該流域水資源的閤理配置提供理論依據。

Based on the runoff data from six hydrological stations in the mountain headstream area of T arim River Basin from 1957 to 2008, the intra-annual variation of runoff w as analyzed using the non- paramet ric t est and w avelet analysis. The results show ed that the monthly runoff, and runoff during the high- and low-flow periods in the headstream area increase significantly;in mountain headstream area, the concent ration degree index ( CDI) at the Xiehela hydrological station increases slightly, w hile the indexes at the other five stations ( Shanliguilank, Kaqun, Yuzmenlek, T ongguzlek, and Wuluw ati) decrease; The concentra-tion degree indexes of runoff in the mountain headstream area has a significant period of 3 to 8 years. Overall, the results of the study can provide a scientific basis for realizing the sustainable use of water resources in the Tarim River basin.
