摘　　要：以塔里木河流域某河道为研究对象,基于已有水文地质资料,研究近年来该河道的年平均分段冲淤量、年平均累积冲淤量和冲淤规律,并系统分析了河床冲淤的原因。结果表明,各枢纽河道段的河床冲淤变化形式呈现为先淤积后冲刷或持续冲刷趋势;河床自然冲刷量占冲刷总量的2.44%,采砂占比29.53%,无规划采砂和航道整治占比68.03%,采砂活动是造成河床冲刷的主要原因。This study takes a river in the Tarim river basin as the research object,based on the existing hydrogeological data,the research on the annual average subsection scour and deposition volume,the annual average cumulative scour and deposition amount and the law of erosion and deposition are analyzed systematically of the river in recent years.The results show that the riverbed scour and siltation in each hub channel section usually shows a trend of first silting and then scouring or continuous scouring;the natural scour of the river bed accounts for 2.44%of the total scour,and the sand mining accounts for 29.53%,and there is no planned sand mining and waterway remediation accounted for 68.03%,and sand mining was the main cause of river bed erosion.
