为探讨长沙市中心城区居住用地扩张特征及影响因素，对长沙市居住用地的合理布局提供借鉴。以1979年、1990年、2003年及2010年城市总体规划为基础，借助不同年份的统计年鉴，采用居住用地扩张速度、居住用地扩张弹性系数及不同时期的居住用地的叠加，对长沙市中心城区居住用地的扩展特征与影响因素进行了系统分析。结果表明：（1）从1949年到2010年长沙市中心城区居住用地增加了7582．52×10^4m^2，年均增长速度为6．4％。（2）1979～1990年居住用地在旧城区的基础上往东发展，扩张半径较小；1990-2003年延续1979～1990年扩张方式之外，出现了一些类似于“飞地”性质的居住用地；2003—2010年居住用地扩张速度加大，湘江西部、城市南部及北部居住用地的面积明显加大。

To probe into the expansion characteristics and influencing factors of residential land in the center of Changsha, to provide some references for the reasonable layout of residential lando Based on the urban overall plan in 1979, 1990, 2003 and 2010, with the aid of different years statistics yearbook, by studing indexes such as the residential land expansion speed, expansion elasticity coefficient and the superposition of residential land in different periods. The results show that：（1） the residential land in the center of Changsha from 1949 to 2010, increased by 7582. 52 million square meters, with an average annual growth rate of 6.4%. （2） the residential land developed towards the east on the basis of old city from 1979 to 1990, with small expansion radius; from 1990 to 2003 continued expansion way outside the same as 1979 - 1990 years, there was some similar to the ＂en- claves＂ nature of the residential land; from 2003 to 2010 period, the residential land expansion increases the speed, residence land in the western of Xiangjiang river, the north and south of the city significantly increase.
