卫星遥感初探安固里淖退缩——干涸历程

Primary exploration the course of the recession-dry of the Anguli Lake using satellite remote sensing

安固里淖卫星遥感图像（Landsat-TM）显示，安固里淖外围有多层弧形线影像。研究认为，这样的影像是安固里淖退缩干涸过程的遗留痕迹，且可与干涸的罗布泊相对比。由此认为，安固里淖退缩干涸经历了很长的历史阶段，最近几年彻底干涸，只是整个退缩干涸过程的一个阶段。

There are several arc-line images in the periphery area of the Anguli Lake on the satellite remote sensing image. Through carefully studying, these images are regard as the marks left by the ancient Anguli Lake in the course of its recession . And, these arc-line images are similar to the Luobu Lake in the north west China. According to the character of remote sensing image, we surmise that the recession of the Anguli Lake has been gone through a long period of time. The lake covered up to 270 thousand mu when it was the largest. The Anguli Lake getting completely dry in recent years , it is only one stage of the course of its long-term recession.
