摘　　要：基于1989和2001年两个时期的LandsatTM假彩色合成影像,在遥感与GIS支持下分析了1989～2001年哈尔滨市城郊土地利用变化态势。研究表明:土地利用转换趋势表现为天然湿地、草地减少,城市建设用地增加,耕地内部水田和旱地略有增加;天然湿地和草地减少已带来土地退化等严重负面效应。In this paper, supported with remote sensing and GIS, we analyze the land use change situation at the suburban area of Harbin City based on two sequences of classified Landsat imagery data dating form 1989 to 2001. The result shows natural wetlands and grasslands reduced while urban construction site, dry farmland and water farmland increased in some degree. The reduction of natural wetland resources and grassland has brought to a serious negative effect such as land degradation, and so on.
