摘　　要：利用1989年和2001年2期TM卫星遥感数据及辅助数据,运用遥感和地理信息系统技术,通过植被指数、土地利用变化、景观格局变化3个方面的监测分析,研究宿迁市生态系统健康状况的变化趋势.结果表明,10年间农田减少,城乡居住地增多,植被指数略有下降,景观格局发展趋势良好,宿迁市生态系统健康有下降趋势.The change trend of ecological system of Suqian city was studied using the TM data of 1989 and 2001. The technologies of remote sensing and GIS were adopted, and the monitoring targets were vegetation index, land use change and the change of landscape. The study results indicated that the area of farmland decreased, the area of place for residence increased, the vegetation index decreased slightly, the development trend of landscape was good. It was evaluated that the health state of ecological system of Suqian showed that tendency of decrease.
