Research on Measurement and Promotion Strategy of Commercial Space Vitality in Old Urban Area Based on POI——Take Huainan Old Urban Area as an Example

受到时代转变的冲击,老城区作为"前活力中心"面临着"被边缘化"的发展困境。城市商业设施的聚集度和多样性一定程度上反映城市空间的活力,以大数据方法探讨老城区商业活力特征、影响机制和提升策略对研究旧城更新有重要意义。本文以淮南市老城区为例,首先基于POI数据从设施密度、混合度和空间可达性对淮南市老城区传统商圈的空间活力进行测度与横向对比,探讨老城区商业现状发展格局和空间分异特征。其次,根据各商圈活力测度结果,验证淮南市老城区商圈的发育与规划实施情况。最后,基于淮南老城区各商圈活力特征的差异性和影响要素的特异性,针对性地提出了"关注适度聚集的功能复合策略""重视公交导向的交通可达策略""强调目标引领的分类引导策略"的老城区商业空间活力复兴策略,以期为其它地区老城区商业活力测度方法与提升思路提供借鉴和参考。
