摘　　要：为了探明塔里木河干流英巴扎至乌斯满河道的演变规律和趋势,对该河道1993—2022年间的Landsat系列卫星影像进行了解译,通过数字岸线系统分析了河道变迁速率。从1993年至2022年,英巴扎至乌斯满河段弯曲系数总体呈现上升趋势,河道呈淤积态势。英巴扎至沙子河口生态闸段相比于沙子河口至乌斯满段演变幅度更加剧烈,且河道往南北两岸的最大迁移速率分别为20.01 m/a和40.36 m/a。2010—2011年裁弯取直现象频发,平均变迁速率最大为72.27 m/a。基于卡尔曼滤波器对2032年河势演变趋势进行预测,河道上段最大迁移距离可达730 m,下段为218 m。应对河道上段进行整治,调整水流和控制河势,以确保河道两岸防洪安全和岸线的合理利用,提高向下游生态输水的保证率。In order to explore the evolution characteristics and trends of the main channel from Yingbazha to Wusiman in the Tarim River.The landsat satellite images of this river reach from 1993 to 2022 was the interpreted and the migration rate of river centerline has been analyzed by using a digital shoreline system.It is found that the bend coefficient in the study reach shows an overall increasing trend,and the main is in the status of sedimentation from 1993 to 2022.The ecological control section from Yingbazha to Shazihekou experiences more intense changes compared to the section from Shazihekou to Wusiman,with maximum migration rates of 40.36 m/a and-20.01 m/a towards the left and right banks,respectively.Channel straightening occurs frequently during 2010—2011,with the maximum average migration rate reaching 72.27 m/a.Based on Kalman filtering,the prediction was made for the river profile evolution trend in 2032,indicating a maximum migration distance of 730 m in the upper half of the study reach and 218 m in the lower half.It is necessary to carry out regulation measures in the upper half of the reach,ensuring flood control safety on both sides of the river and rational utilization of the shoreline by adjusting the water flow and controlling the river regime,and improving the guarantee of ecological water delivery.
