历史街区中人群活动偏好的主体差异及其影响因素——以昆明市文明街历史街区为例

Subject Differences and Influencing Factors of Crowd Activity Preferences in Historic Districts:a Case Study of Wenming Street Historic District in Kunming City

探讨历史街区中人群活动偏好的主体差异及影响因素对营造全龄友好的历史街区环境有重要意义。以昆明市文明街历史街区为例,结合调研数据和网络开源数据构建指标体系,通过对比青少年和中老年人群活动强度的空间分布差异归纳各自的活动偏好,借助逐步多元线性回归分析揭示其受建成环境影响的因素。发现历史街区中人群活动偏好存在主体差异,青少年活动偏好受到餐饮设施密度、适宜步行宽度、购物设施密度和历史资源分布的显著影响;中老年人群活动偏好受到功能设施密度、公共交通便捷度和适宜步行宽度的显著影响。在此基础上提出适应全龄友好的空间优化策略,以期为历史街区保护与更新实践提供借鉴。

Discussing the subject differences and influencing factors of crowd activity preference in historic districts are of great significance to creating a friendly environment in historic districts for all ages.Take the Wenming Street Historic District in Kunming City as an example,combine survey data and online open-source data to construct an indicator system.By comparing the spatial distribution of the activity intensity of adolescents and middle-aged and elderly groups,they can summarize their respective activity preferences,and use gradual multiple linear regression to reveal their respective completions.Environmental factors.It is found that there are subject differences in the activity preferences of the crowd in the historical district.The activity preference of adolescents is significantly affected by the density of dining facilities,suitable walking width,shopping facility density and the distribution of historical resources;the activity preference of middle-aged and elderly people is significantly affected by the density of functional facilities,the convenience of public transportation and the suitable walking width.On this basis,a space optimization strategy suitable for all ages is proposed,in order to provide a reference for the protection and renewal practice of historic districts.
