摘要(Abstract)：

针对西北部少数民族地区城市扩展定量信息缺乏的问题,该文选取1997—2017年Landsat遥感影像为数据源,以呼和浩特市为例,开展遥感监测。以城市扩展速度、扩展强度、扩展变化度和面积变化度作为指标,剖析呼和浩特市城市扩展的时空特征,耦合自然、人口、经济和政策等多方面因素,探讨西北部少数民族地区城市扩展的主要驱动力。结果表明:①近20年来,呼和浩特市城市扩展先后经历了一个中速扩展阶段、两个快速扩展阶段和一个高速扩展阶段,扩展速度稳步加快;②呼和浩特市城市扩展以东西方向为主轴线,城市扩展整体呈现核心-轴线延伸扩展模式;③自然条件限制和人口快速增长是西北部少数民族地区城市扩展的主要驱动因素,而经济和政策规划对扩展导向的影响正在逐步增强。

关键词(KeyWords)： 遥感;城市扩展;时空特征;呼和浩特;驱动力分析
