中文摘要	科学认识气候变化与人类活动影响下,以径流为主要指征的水循环过程及其变化,是合理利用水资源的前提,对于认识水文机理,应对径流变化具有重要价值。选取干旱区内陆河流叶尔羌河卡群断面1957-2015年长系列实测月径流系列、1962-2015年长系列实测月气温与降水系列,采用年内分配完全调节系数C_r、年内分配不均匀系数C_n、相对变化幅度C_m、集中度C_d、集中期D、年际径流均值、最大流量及出现时间、最小流量及出现时间、年际极值比等多指标,运用Mann-Kendall法、累积距平法、R/S法、排列熵法等多方法,揭示叶尔羌河径流演变规律与变异特征,并进行归因分析。结果表明:近60年来,叶尔羌河流域径流量年内分配趋均匀化、年际变化呈显著增多趋势且为正持续性,其中1957-1961年和1993-2015年为显著径流增加时段; Mann-Kendall法与排列熵法均证实了1997年为该径流序列的突变点也为变异点;气温,特别是夏季7-8月平均气温(相关系数为0.81)为叶尔羌河径流量变化的主要影响因素。
英文摘要	Under the influence of climate change and human activities,the process of water cycle with runoff being the main indication and its change is the prerequisite for rational utilization of water resources. It is of great value to understand the hydrological mechanism and to cope with the change of runoff. In the period from 1957 to 2015,the series of monthly runoff series and the temperature and precipitation series from 1962 to 2015 in the Yarkant River fracture surface of inland river flows in arid area were selected. The distribution coefficient C_r,the distribution inequality coefficient C_n,the relative variation range C_m,the concentration ratio C_d,the concentration period D,the interannual runoff average,the maximum flow rate and the time of occurrence,the minimum flow rate and the time of occurrence,the inter-annual extreme value ratio were adopted as indicators using Mann-Kendall method,cumulative anomaly method,R / S method,the entropy method and so on,the evolution law and variation characteristics of the runoff the Yarkant River were revealed and the attribution analysis was carried out. The results showed that in the past 60 years,the annual runoff distribution in the Yarkant River Basin tends to be homogenized during the year,and the interannual variation shows a significant increase tendency and is persistent,among which 1957-1961 and 1993-2015 are the significant runoff increasing periods. Mann-Kendall method and the distribution entropy method all confirmed that the mutation point of the runoff sequence was also the point of variation in 1997. The temperature,especially the average temperature in summer from July to August (correlation coefficient is 0.81) was the main influencing factor of runoff in Yarkant River.
