Vitality Analysis and Strategy Research of Historical and Cultural Districts Based on POI—Taking Xiaohe Street in Hangzhou as an Example

历史文化街区是凝聚着城市历史风貌与地域文化特色的容器，使其得到可持续发展对于历史文化的保护和传承有着重要意义。本研究以杭州市拱墅区小河直街历史文化街区为例，基于POI和百度热力图等网络开源数据分析街区活力，将其与商业业态进行对比分析以探讨二者关联性，并从业态角度总结街区现存问题。研究发现：现状街区存在单一业态类型重复且分布不均、功能业态分布失衡且混合度不高、街区活力差距大，部分区域荷载过度等问题。基于上述结果，对小河直街历史文化街区的活力提升提出优化策略，以期推动历史文化街区可持续性发展。
