基于遥感的长时间序列下巴丹吉林沙漠湖泊演化分裂特征分析

巴丹吉林沙漠内湖泊已存在达千年尺度，其地表残留的湖泊演化分裂特征可部分反映地下水变化规律。以往研究多依赖水化学特征的解释，本次基于国产高分卫星数据，从遥感的角度对巴丹吉林沙漠内124个古湖的演化分裂特征进行提取。研究区湖泊水体分裂特征模拟结果显示，巴丹吉林沙漠内湖泊在长时间尺度下的演变分裂特征明显、分类聚合形式显著，宏观上各演化分裂特征区间由东南向西北展布，但与研究区地形变化趋势不完全相同，二者在局部存在显著差异。

The Analysis of Evolution Characteristics of Badain Desert Lake Based on the Long Time Series of Remote Sensing

Badan Jaran Desert lakes existed for thousands of years, the characteristics of the evolution and division of the residual surface of the earth surface can partly reflect the variation of groundwater. Previous studies tend to explain the hydrochemical characteristics of the domestic high. From the remote sensing perspective evolution and division of 124 ancient lake in Badan Jaran Desert have extracted based on the satellite data. The lake water splitting simulation of the study area shows that the long time evolution division features and the form of classification and aggregation of Badan Jaran Desert lakes are remarkable. Through the macro view the characteristics of evolution and division distributed from the southeast to the northwest, but this is not exactly the same with the trend of the study area, and the two are significant differences in the local.
