摘要: 以1991年、2001年与2006年的Landsat TM/ETM+影像为数据源,利用几何校正、监督分类、动态变化分析等遥感技术对延吉市1991~2006年的土地利用动态变化情况进行了统计和分析。研究结果表明,延吉市的居民用地面积显著增加,而农田和草地的面积却大面积减少,由此引发的粮食和环境问题将严重影响延吉市居民的日常生活和自然生态环境。研究结果可为延吉市的可持续发展和有效管理提供理论基础和依据。

Abstract: The dynamic change of land use in Yanji City was computed and analyzed by using the geometric correction, supervised classification and change detection statistical methods based on 3 Landsat TM/ETM+ images taken in 1991, 2001 and 2006. The results showed that, the area of residential land has increased significantly. On the contrary the area of agricultural land and grassland has decreased. The grain problem and the environment problems due to the changes of the land use would seriously affect the daily life and the ecological environment of Yanji City. The result of the study could provide a theoretical basis for the effective management and sustainable development of Yanji City.
