本文利用2013年4月18日获取的天宫一号高光谱成像仪数据和1985年5月1日获取的Landsat TM数据,对黄河入海口地区湿地的土地利用状况进行了监测研究.通过对比分类结果发现,该地区近30年来人类活动对湿地的影响强烈,滩涂开垦、水产养殖业占用自然水面现象严重.同时由于天宫一号高光谱成像仪数据具有更高的光谱和空间分辨率,其分类精度优于Landsat TM,更适合于湿地的监测.

In this paper, the Tiangong-1 hyperspectral data acquired on April 18, 2013, and a Landsat TM imagery acquired on May 1, 1985 were using to monitor the wetlands changes in Yellow River estuary. By comparing the classification results of Tiangong-1 hyperspectral data and Landsat TM imagery, the result showed that the decrease in wetlands areas was largely affected by the human activities in the past 30 years, such as beach reclamation and aquaculture. Furthermore, the Tiangong-1 hyperspectral data performed better on wetlands monitoring than Landsat TM due to its higher spectral and spatial resolution.
