摘　　要：文章利用多源卫星遥感数据,研究巴丹吉林沙漠和亚玛雷克沙漠之间连接带的时空变化特征。结果表明:1988-2019年期间,巴丹吉林沙漠与亚玛雷克沙漠之间连接带的平均宽度总体呈增加的趋势,增宽65.34 m;前期(1973-2013年)沙漠连接带宽度减小,后期(2013-2019年)沙漠连接带宽度增加,但不同位置沙漠连接带的宽度变化有差异,且连接带西北部宽度的增加更明显;连接带内部沙丘位移整体朝向为东南方向,但2015-2019年期间其移动方向以西北为主;连接带的东南侧由于大沙丘的分裂,沙丘规模发生小型化,其格局表现出细密化;连接带早在1973年时已有一定规模,且大于相同位置2019年宽度均值,说明两个沙漠连接的发生、发展(握手、拥抱)不是近几十年才开始。Using multi-source satellite remote sensing data to study the characteristics of temporal and spatial changes in the link belt between the Badain Jaran sandy Desert and the Yamalek sandy Desert. The study found that during 1988—2019, the width of the link belt was increased by 65.34 meters. In terms of specific time, it first decreased in 1973—2013 and then increased in 2013—2019,and the width of the northwestern part of the link belt increased more. The dunes in link belt moved southeast, but from 2015 to 2019,the northwest direction is the main direction. The large sand dunes on the southeast side of the link belt split and the sand dunes are miniaturized. The desert link belt had a certain scale as early as 1973, and was larger than the average width of the same location in 2019, indicating that its development did not start in recent decades.
