摘　　要：随着城市化进程的加快,城市建设用地扩张成为人地关系及可持续发展面临的重要问题,社会各界对城市化与建设用地扩张的关注也越来越多。以长春市中心城区为研究对象,利用1800~1995年统计资料,1995年、2000年、2005年和2010年的遥感影像图及规划统计数据,运用GIS技术提取城市建设用地规模、形态、增长幅度、平均中心等信息,建立一种在空间上有效识别城市建设用地扩张的简便方法,对研究区1995~2010年不同阶段的城市建设用扩展进行空间识别,计算城市建设用地扩张速度、强度、形态紧凑度、分维指数等空间特征量,归纳长春市1995年以来,随城市化发展,城市建设用地空间扩张现象和特征。并结合经济社会统计相关数据及区域分析方法,分析城市建设用地扩张与其各类驱动要素之间的关系。结果表明,长春市建设用地空间扩张与形态演化既具有一般规律又具备特殊性,表现出建设用地总量增加、产业拉动性强、扩张速度快、强度高、空间形态不规则、城市中心迁移方向与建设用地扩张基本一致等特征。这些现象和特征形成的主要影响因素为快速城市化背景下开放式交通系统的高密度开发。With the progress of urbanization accelerating, urban construction land expansion has been an important problem which man-earth relationship and sustainable development have to be confronting with. All social circles also pay more and more attentions to these situations. This article takes the center city of Changchun as the research object, using the statistics data from 1800 to 1995, remote sensing map and planning statistics of1995,2000,2005 and 2010, to extract the information of urban construction land scale, forms, increasing ranges, mean center by GIS, establish a simple way to identify the urban construction land expansion from 1995 to2010 effectively, calculating the spatial characteristic quantity such as speed, strength, form compact degree and fractal dimension of urban construction land expansion, so as to generalize its situations and characteristics of Changchun along with urbanization since 1995. Combining with the economic social statistical data and region analysis method, to analysis the relationship between the urban construction land expansion and its various driving factors. The results show that urban construction land expansion and morphological evolution in Changchun possess its general law and specificity, construction land increasing, Industry-pull strength, fast sprawl, high strength, spatial imbalance, the similar direction between city expansion and construction land expansion. The major factor of the situations and characteristics is high density developing of opened traffic system under the atmosphere of rapid urbanization.
