摘要
利用GIS和遥感技术对不同时期的地形图和遥感影像数据进行处理,获取3个时期（1971,1988,2002年）的太湖流域主要湖泊的水域面积.结合多种文献资料,对太湖流域主要湖泊的水域面积变化进行了研究,并分析了引起水域面积变化的主要因素.结果表明,1971～2002年期间太湖流域主要湖泊的水域面积减少了188.87km^2;湖泊水域面积减少的主要原因是由于人类活动的影响.在实地调查研究的基础上,对合理利用与保护湖泊水资源的对策进行了探讨。
Topographical map and remotely sensed images at different times were selected to investigate the surface area change of major lakes in Taihu Basin during three stages by GIS and RS techniques. Based on literatures and present situations, major factors that cause the change of acreage were analyzed. Results show that the decrease of area from 1971 to 2002 was 188.87km^2, and the major factors were human activities. Based on field survey and investigation, some suggestions were given on the utilization and protection of water resources.
