摘　　要：以Landsat卫星数据为基础,以GIS为技术支撑,选取城市用地扩展速度、扩展强度指数、分形维数、紧凑度等城市形态指标,实证分析1990-2017年佛山市建成区外部形状的变化过程。结果表明:1)1990-2000年佛山市城区的空间扩张是一个飞跃增长型,2000-2009年是平稳增长型,2009-2017年是快速增长型,城市重心往西南方向发展;2)佛山市城区扩张以外向型扩展和内向填充型两种方式并存。研究结果可为佛山城市总体规划及综合管理提供科学依据。Based on Landsat data, we calculated urban expansion speed index, urban expansion intensity index,fractal dimension and compactness index, and analyzed the spatial change of the built-up area in Foshan city during 1990 to 2017 using GIS technology and spatial analysis method. Results showed that: 1)From 1990 to2000, Foshan’s urban expansion was a leap-forward growth. From 2000 to 2009, it was a steady growth. From2009 to 2017, it was a rapid growth. The city’s center of gravity moved to the southwest. 2) Foshan urban expansion had two modes: outward expansion and inward filling. The results of this study are expected to provide a scientific basis for the urban planning and general management of Foshan City.
