中文摘要：

塔里木河位于塔克拉玛干沙漠，其河床演变和河道整治对保护塔里木河具有重要的意义。通过水沙特征分析，塔里木河年输沙量变化与年径流量的丰枯变化相应；输沙量和径流量年内高度集中，最大4个月出现月份基本一致，最大4个月的年内集中程度均大于70％。绎过河床稳定性计算，上游阿拉尔站和新渠满站纵横断面不稳定，中游大坝站相对稳定。从河道冲淤变化来看，淤积量大于冲刷量，河床总体趋势为抬升；由于上中游河道断面变化频繁，洪水漫溢严重，必须进行河道整治。针对塔里木河的特点，提出了河道整治措施，分析了河道整治对生态环境的影响，探讨了生态环境保护的对策。

英文摘要：

Tarim River lies in Takilamakan desert, so studies on riverbed evolvement process and channel regulation have significance for the river protection. Through water and sand characteristics analysis, it is found that annual sediment load varies with annual runoff in the river, and annual distribution of sediment load and runoff mainly concentrates in June to September with a ratio beyond 70%. Stabilization of riverbed is calculated, and it is drawn that the longitudinal section and cross section of Alaer Station and Xinquman Station are not steady, while the Daba Station is steady. The riverbed elevation has the trend to increase because sedimentation is more than sluicing. Flood overflowing is severe due to frequent changes in the cross section ate the upper and middle reaches. So, it is necessary to regulate the river. River regulation measures are put forward according to the river characteristics, ecological environment influence and countermeasures are discussed in the end.
