摘　　要：针对城市建成区的空间异质性不能反映城市居住空间结构的问题,该文选取南京市中心城区(长江以南)2001—2007年的新增居住用地,从扩展方位和强度两方面分析空间扩展特征,以直方图和Logistic回归模型揭示主导驱动因素。结果表明东北、东南、西南方向是新增居住用地的3个主要扩展方向,分别对应仙林新市区、东山新市区和河西新城区;居住用地扩展是多种驱动因素共同作用的结果,人口和经济驱动因素对郊区居住用地增加影响显著,对主城区影响有限,自然和政策驱动因素中反映政府政策的政府建设用地规划区是最重要的主导驱动因素,其次为与小学的距离,最后为与地铁站点的距离。For the problem that the spatial heterogeneity of urban construction land couldn＇t reflect urban residents＇ spatial structure, the new residential land of the Nanjing downtown （south of the Yangtze River） in 2001-2007 was studied. The spatial expansion characteristics was analyzed by expansion position and strength, and the main driving forces were revealed by histogram and logistic model. The result showed that the northeast, southeast and southwest directions were three main expansion directions of the new residential land, corresponding to Xianlin new urban area, Dongshan new urban area and Hexi New Town and residential land expansion results from a variety of driving factors. Population and economic drivers affected the increase of residential land significantly in the suburbs, but had a limited influence on the main city. In the analysis of natural and policy driving factors, construction land planning area of the government which reflected government policies was the most important driving factor, the second one was the distance to the elementary school, and the third one was the distance to the subway stations.
