摘要： 为研究太原市城市扩张动态变化，采用 DMSP/OLS(Defence Meteorological Satelite Program/Oprational
Linescan System)夜间灯光数据结合统计数据法提取城市建成区，提出加权重心转移法提取城市重心，并从用地扩
张时空特征、城市扩张类型、基于灯光强度的城市重心迁移几个方面展开研究。结果表明，太原市城市建成区持
续扩张，且城市重心不断向南移动。1992 ～2002 年，太原市主要扩张走势为向西以及西南方向扩张，为填充增强
主导扩张类型; 2002 ～2012 年扩张强度尤其明显，主要扩张走势为正南、东南方向扩张，为外延主导扩张类型。

Abstract: To study the dynamic changes in urban expansion in Taiyuan，extracting urban built-up areas using
DMSP/OLS( Defence Meteorological Satelite Program/Oprational Linescan System) nighttime lighting data
combined with statistical data method，weighted center of gravity transfer method is proposed to extract the
center of gravity of a city． The main research areas are the spatial and temporal characteristics of land
expansion，the type of urban expansion，and the shift of city center of gravity based on light intensity． The
results show，Taiyuan City's urban built-up area continues to expand and the city's center of gravity is moving
southward． From 1992 to 2012，the main expansion trend of Taiyuan City is westward and southwest and
enhance the dominant expansion type for filling． From 2002 to 2012，the intensity of expansion is especially
obvious，the main expansion trend is south and southeast and is leading type of extension．

Key words: defence meteorological satelite program/oprational linescan system ( DMSP/OLS ), urban expansion, weighted center of gravity transfer method, statistical data method
