摘要
针对红碱淖湖泊水量锐减问题,通过构建面积和高程关系得到红碱淖湖盆模型,研究红碱淖湖盆模型得到红碱淖湖泊水量变化情况。首先在GEE软件上利用Landsat影像提取红碱淖水体,计算出每年7-9月的红碱淖湖泊面积,根据ICESat和ICESat 2卫星测高数据获得湖泊高程,构建红碱淖湖泊的湖盆模型,通过模型分析得出水量变化情况。研究结果表明:通过水体面积与测高数据构建的湖盆模型反映红碱淖水量变化情况的方法更科学。
In view of the sharp decrease in the water volume of Hongjiannao Lake,the Hongjiannao Lack and basin model was obtained by building the relationship between area and elevation,and the water volume change of Hongjiannao Lake was obtained by studying the Hongjiannao Lake basin model.Firstly,the water body of Hongjiannao Lake is extracted from Landsat image on GEE software,the lake area of Hongjiannao Lake is calculated from July to September every year,the lake elevation is obtained according to ICESat and ICESat 2 satellite altimetry data,and the lake basin model of Hongjiannao Lake is constructed,and the water volume change is obtained through model analysis.The research results show that the lake basin model constructed by water area and altimetry data is more scientific in reflecting the water volume change of Hongjiannao Lake.
