中文摘要：

基于1996、2000、2005和2011年4期TM遥感影像,利用ArcGIS空间分析功能,研究了广州市建设用地时空变化状况。结果表明,研究时段内广州市建设用地共扩展413.44km2,属快速扩展时期,且扩张速度越来越快。建设用地斑块个数、平均斑块面积、最大斑块指数和紧凑度越来越大。增城区和从化市等建设用地主要呈零星式和蔓延式扩张,而市辖区、番禺区、南沙区和花都区建设用地主要呈填充式和蔓延式发展;建设用地扩张以东南方向（番禺区、南沙区）和西北方向（花都区）为主,其次为增城区和从化市。人口增长、经济发展、规划与政策和交通建设是影响广州市建设用地扩展的主要驱动力因素。

英文摘要：

On the basis of four TM remote sensing imageries in 1996, 2000, 2005 and 2011, this paper studied the temporary and spatial changes of Guangzhou construction lands during the past 15 years by using ArcGIS spatial analysis tools. Results showed that the construction lands of Guangzhou city expanded about 413.44km2 during the past 15 years. The expansion speeds became faster and faster, belonging to the rapid expansion phase. The plaque number, average patch area, largest patch index and compactness of Guangzhou construction lands also increased year by year. The expansion types of construction lands in Zengcheng and Conghua Districts mainly belonged to sporadic and spread models, while the expansion type of construction lands in Guangzhou urban regions, Panyu, Nansha and Huadu District mainly belonged to filled and sprawl models. The main expansion directions of Guangzhou construction lands were toward Panyu and Nansha Districts in southeast and Huadu District in Northwest. Population growth, economic development, planning and policies, and traffic constructions were four major driving factors determining construction land expansion of Guangzhou city.
