以太原市主城区作为研究区域,基于兴趣点(Point of Interest,POI)数据,采用核密度分析、局部Getis-OrdGI*指数等方法,对城市商业空间格局进行了研究,在其现有商业空间格局的基础上借助等值线树法对商业中心进行了识别,并对各类行业的空间分布及集聚特征进行了对比分析.结果表明:太原市主城区商业空间已经形成了以柳巷、朝阳以及亲贤北街商圈为中心向外围扩散的分布格局,体现出汾河以东集中连片、汾河以西零星分散的分布特征;识别出太原市主城区内46个基本商业中心,其中以柳巷、朝阳—双塔、体育路—亲贤北街为主城区三大核心商业中心;各类行业空间聚集表现不同,生活服务类、购物服务类以及餐饮服务类行业分布范围广、集聚程度小,医疗保健类、商务服务类、金融服务类行业分布范围小、集聚程度高.
