摘　　要：利用遥感技术和地理信息系统相关软件对聊城市1987年和2000年两期遥感影像进行处理,提取水体分类图,计算出两个时期主要水域面积变化,重点分析了东昌湖6个湖区的水域面积变化数据。研究表明聊城市的主要水域减少了20.59%,湖泊水域面积增加了10.97%。Using software about remote sensing technology and Geographic Information System, the paper processed the Remote Sensing image data in 1987 and 2000 in Liaocheng, and extracted water classification map, then calculated major water area changes and Dongchang lake＇ s six Lakes area of waters change data from 1987 to 2000. The research shows that the overall Liaocheng waters significantly reduce by 20.59%, instead fairmont area of the lake waters increased by 10.97%.
