摘要
用两个时期的ＬａｎｄｓａｔＴＭ遥感图象，经多种技术的图象处理，特别是图象自动分类识别和两个时相遥感图象的交叉分析处理，对江苏省扬中市的土地利用现状进行了动态监测。发现扬中市的土地利用类型发生明显变化，城市的扩展使耕地锐减。
Land use change of Yangzhong city by remote sensing technique was studied using two phases of Landsat TM images and several kinds of image processing techniques. Very significant changes of land use were revealed in the city as cultivated land was decreased remarkably due to fast urbanization. It was necessary to monitor the land use now and then, which could be well done by remote sensing technique.
