摘　　要：利用遥感技术快速准确地获取城市扩张信息并分析其驱动力机制,快速有效地监测城市温度场分布,对于指导城市规划、优化生态环境等问题有重要的意义。采用1988年和2001年2个时相的TM/ETM+卫星遥感图像,在地理信息系统(GIS)的辅助下,对阜新市城市扩展及城市热岛效应进行了研究,结果表明阜新市总体城市扩展方式为沿煤矿采场走向上呈轴向扩展,2001年后主要向西部和南部扩展;煤矿露天采场及其排土场对阜新市的城市热岛效应具有重要影响,为今后阜新市城市发展规划提供了决策参考。It is very important for us to make urban plan and optimize ecological environment, analyze the urban expansion drive mechanism and monitor the urban temperaturefield distribution by using the rapid and accurate remote sensing data. The urban expansion and urban heat island effect are studied by means of data from 1988, 2001 TM/ETM＋ images and GIS method. The results indicate the overall urban expansion along the long axis of the coal open-pits and the expansion after 2001 mainly to the western and southern parts; The coal open-pits and the dumps are of great significance for urban heat island effects, which provides certain decision-making references for future urban planning of Fuxin city.
