基于Landsat影像的洪泽湖水面面积及其变化分析

Hongze Lake Water Surface Area Based on Landsat Image and Its Change Analysis

针对洪泽湖水域环境急剧变化的问题,湖泊水面面积变化监测成为湖泊遥感调查中一项必不可少的工作。利用中分辨率卫星平台Landsat监测所得数据TM/ETM+/OLI对洪泽湖水面近十年来水面面积进行监测,分析洪泽湖水域面积变化趋势。结果表明,十年来洪泽湖水面面积呈现减少趋势,且以洪泽湖北部与西部最为显著。

Against the rapid change of water environment in Hongze Lake, the change monitoring of the lake water area becomes an essential work in the remote sensing survey of the lake. The Hongze Lake water surface area in recent ten years is monitored with middle resolution satellite platform Landsat based on the data TM/ETM+/OLI to analyze the variation tendency of the water area of Hongze Lake. The result shows that the water surface of Hongze Lake has tended to decrease for ten years, which is most significant in the north and west of Hongze Lake.
