摘　　要：为分析气候变化和人类活动对叶尔羌河水沙的影响,运用模比系数差积曲线法、滑动相关系数法和双累积曲线法,研究叶尔羌河水沙变化趋势,并诊断水沙相关程度和变异点。结果表明:叶尔羌河径流量和输沙量总体上呈增加趋势,径流量和输沙量主要来自于夏季;径流量和输沙量以1993年为界划分为枯水(沙)期和丰水(沙)期;水沙相关度在1993年后变化明显,降水量对径流量和输沙量变化的影响表现为降低趋势,人类活动对径流量和输沙量变化的影响呈现上升趋势,降水仍是径流量和输沙量变异的主导因素。In order to analyze the influence of climate change and human activities to the runoff and sediment of Yarkand River,using the differential coefficient plot of the modulus coefficient,the sliding correlation coefficient method,and the double mass curve method,the trends of water and sediment development in the Yarkand River were studied,and the variation points of water and sediment correlation degree were diagnosed.The results show that the runoff and sediment transport of Yarkand River are increasing on the whole,and the contribution of runoff and sediment transport mainly comes in summer;the runoff and sediment yield are divided into one cycle of dry years and one cycle of wet years in 1993;the linear relationship of multiple regression shows that the correlation between water and sediment has been changed significantly around 1993.The influence of precipitation to the runoff and sediment transport shows a downward trend,while the influence of human activities to the runoff and sediment transport presents an upward trend.Precipitation is still the dominant factor for the variation of runoff and sediment transport.
