Based on remote sensing image from the series of Landsat satellites, residential space features in Xi’ an metropolis was extracted by supervised classification of neural network in 2000, 2004, 2009, 2013, respec-tively, and the spatiotemporal evolution characteristics were also analyzed. The results indicate that (1) A signifi-cant increasing trend was detected in residential space during 2000—2013, with an increasing area of 872.26 km2 . Meanwhile, the phase of residential expansion followed a fast-slower-faster pattern. In spatial, new residential spaces are mainly around urban area, compared to a discrete distribution in the past. (2) The pattern of residential space development will be dominated by concentration based urban in Xi’ an. However, prefecture-level cities and county town will be the potential development area for residential space. (3) The population development lagged the expansion of residential space. Owing to the population carrying capacity surplus, Xi’ an suburbs and part of the county towns will be the main inflow areas for urbanization population. (4) The development of residential space lagged the industrial and service industry development, but faster than the development of agriculture, which illus-trated a close correlation between the development of urban residential space and industrial and services industry. In addition, the development of rural residential space is also mainly influenced by regional industry and services, ag-riculture only act a supplementary role in residential space evolution.%以Landsat系列遥感影像为数据源,分别提取2000,2004,2009,2013年西安都市圈居住空间信息,并分析其时空变化特征。结果表明：(1)2000—2013年居住空间扩展幅度明显,经历了快-慢-稍快的扩展模式,增加面积为872.26 km2；(2)未来发展仍以大都市中心集聚模式为主,而县城居住地和地级市居住地将是潜在发展区；(3)人口的发展对居住空间的影响具有一定的滞后效应,西安市城郊和县城的人口承载能力相对较大,将是人口城镇化的主要流入地,而其他地级市人口出现负增长；(4)城市居住空间的发展与工业及服务业的承接和演替非常紧密,而农村居住空间的发展同样主要受区域工业和服务业的影响,农业对居住空间演变只起辅助作用。
