摘要
通过卫星遥感图像对楼兰古城地区古河道分布状况进行环境地质解译 ,发现古城所在地上游有两处滑坡 ,且存在堰塞湖。基于这一发现 ,推测楼兰古城最终消亡原因是由于其上游发生滑坡崩塌后堵住河水 ,使楼兰古城因断水而被遗弃乃至消亡。
The disappearance of the ancient Loulan city in Xinjiang has been regarded as a riddle. Through the application of satellite remote sensing technology and the interpretation of the distribution characteristics of the old river in Loulan area from TM image, the authors have found that there are two landslide sites and barrier lakes located in the upper reaches of the river. Based on this discovery, it is thought that the abandoning and final disappearance of Loulan might be attributed to landslides which cut off its water source and broke off its water supply.
