罗布泊盐湖近2000a气候变化的高分辨率遥感研究

High resolution remote sensing research of climatic change of Lop Nur saline in past 2 000 years

根据盐湖演化理论,结合实地调查数据,探讨了罗布泊盐湖记录过去气候变化的理论模型。通过对环状影像的成因进行解译和分析,试图建立影像信息与盐湖近2000a来气候变化的联系。应用遥感方法进行过去2000a气候变化的研究,建立了罗布泊盐湖近2000a高分辨率气候变化曲线。与已知成果进行对比表明,获得的初步结果具有可比性、连续性,特殊气候事件分辨率可达年,一般情况下气候变化的分辨率达10～20a。

According to the evolutive theory of saline and combined with field survey data, the authors (discuss) the theoretical model of recording the past climatic change of Lop Nur saline. After interpreting and analyzing the causes of the ring image, the authors attempt to establish the relationship of the image information and the climatic change of the saline in the past 2 000 years and map high resolution climatic change graph of Lop Nur saline in the past 2 000 years by using the remote sensing method. Contrast to the known results, these research results have comparability and continuity. The resolution of the special climatic event can reach in one year, and in general, the resolution of climatic change can reach in ten to twenty years.
