摘要：

为了获取绥化市城市扩展过程的特征，基于1976、1990、2001、2006和2009年遥感影像资料，利用人机交互解译方法提取了绥化市城市用地扩展信息，借助地理信息系统（GIS）技术的统计分析功能和空间分析功能，分析了绥化市建设用地扩展的数量特征和空间变异特征。结果表明，1976—2009年的33年间，绥化市城市建设用地面积持续增加，其中2001—2009年间的城市扩展规模和速度最大；城市重心先向西北移动，后向西南移动；绥化市建设用地扩展具有明显的空间分异特征，这种特征表现在不同时段城市建设用地扩展的方向不同；城市紧凑度变小，形态特征变复杂。

Abstract:

Based on the remote sensing images of 1976, 1990, 2001, 2006 and 2007, the urban spatial expansion information of Suihua city was extracted with the method of human-computer interactive. This paper focused on the quantitative characteristic and space variation characteristic about Suihua city using GIS technology .The results showed that during the 33 years from 1976 to 2009, the urban area of Suihua increased persistently, especially between 2001 and 2009. The center of the urban land moves to the northwest, then to the southwest. The expansion of urban land had obvious space differentiation characteristics, which showed that the expansion directions of the city were different at different time, city compactness became small and the morphological feature became complex.
