摘　　要：选用 1994 ,1999年 1:5万SPOT卫片作为信息源 ,用MAPGIS作为遥感数据处理的工具 ,对常熟市五乡土地利用状况进行了动态监测 ,结果为五年耕地面积减少 195公顷 ,年均动态率 - 3.7‰。随着地区经济的快速发展 ,土地利用变化显著 ,应用RS和GIS技术对其进行经常性的监测是很有必要的。The dynamic monitoring was made for five towns of Changsu county, using 1:50000 SPOT image data in 1994, 1999 as information sources, and MAPGIS as process tool of remote sensing data. The investigating result showed that cultivated land decreased by 195 ha. in the past five years and the dynamic rate was -3.7 ‰ per year. Landuse is changing obviously because of the economic development in the concerned region. It is necessary to monitor the landuse now and then, which could be well done by RS and GIS techniques.
