资源一号卫星数据在黄河三角洲地区的应用潜力初探

本文在对我国自主获取的资源一号卫星遥感图像--1999年12月22日的黄河口零级数据预处理的基础上, 利用两种方法将它与1996年获取的高分辨率国土普查卫星全色黑白数据进行融合分析,结果提高了资源一号卫星数据的空间分辨率 ,清晰反映出孤岛镇的城镇结构、小麦长势和油井分布。另外,对1999年10月17日的资源一号卫星图像进行了分析,清晰展现了黄河北汊的淤积趋势和小清河的污染扩散。

Primary Explorations of the Applied Potentials of ZY-1 Satellite data at the Yellow River Delta

On the basis of preprocessing the remotely sensed image of ZY-1 satellite of the Yellow River Mouth, level 0, which our country got independently on December 22nd, 1999, we use two kinds of methods to fuse it with the high spatial resolution image of Land Survey Satellite gotten in 1996 As a result, we improve the spatial resolution of ZY-1 satellite image, distinctly reveal the town structure of Gudao town, the way wheat is growing and the distribution of oil wells In addition, we know where the north branch of the Yellow River goes, and how the pollution of the Xiaoqing River diffuses from the remotely sensed image of ZY-1 satellite gotten on October 17th, 1999
