罗布泊盐湖环状影像成因解释

The genesis of the ring salt crust images of the Lop Nur salt lake, (Xinjiang)

根据遥感影像信息特征和盐湖气候变化模型,结合盐湖沉积特征和现代盐湖演化理论,通过对环状影像的成因进行解译和分析,将环状影像反映的1000年来盐湖气候变化的信息与北半球同期气候变化曲线对比,认为罗布泊盐湖是现代沉积形成的,是现代盐湖向干盐湖的演化历程中,由于气候冷暖交替变化而使盐湖沉积发生规律性变化的结果。

The comparative study has been made for the climatic curves which represent the climatic changes during the past millennium in the Lop Nur salt lake and Northern Hemisphere, respectively on the basis of the remote-sensing images and climatic models and the genetic interpretation for the ring salt crust of the Lop Nur salt lake, Xinjiang. The ring salt crust images of the Lop Nur salt lake is interpreted to be caused by the modern sediments as a result of regular salt lake deposition due to the alterating warm and cold climatic changes during the transition of the salt lake from a modern salt lake to a playa.
