| 以芜湖古城为研究对象，研究基于高德地图开放平台获取的地理信息数据集，创新性地采用城市网络分析（UNA）方法，突破传统空间句法在复杂历史街区中的局限性，并结合百度热力图等多源数据，量化分析街道活力的时空分布特征，以此探究街道网络可达性与空间活力之间的作用机制。研究表明，芜湖古城整体活力水平不高，公共服务设施可达性虽较好，但关键节点分布不均衡、道路连通性较弱，导致活力分布失衡。基于此，研究提出提升区域可达性、增强设施引力值、强化路径中间性的针对性更新策略，为实现历史街区文化传承与活力再生的双重目标提供实践路径。 |
| 英文摘要: |
| This study takes Wuhu Ancient City as its research object and innovatively employs Urban Network Analysis (UNA) to overcome the limitations of traditional space syntax in complex historic neighborhoods. By integrating multi-source data such as Baidu Heat Maps, it quantitatively analyzes the spatiotemporal distribution characteristics of street vitality to investigate the interactive mechanism between street network accessibility and spatial vitality. The findings reveal that while the overall vitality of Wuhu Ancient City is relatively low and the accessibility of public service facilities is fairly good, the uneven distribution of key nodes and weak road connectivity are significant factors leading to imbalanced vitality distribution. Based on these insights, the study proposes targeted renewal strategies such as improving regional accessibility, enhancing the attraction value of facilities, and strengthening path betweenness. These measures aim to provide a practical pathway for achieving the dual objectives of cultural preservation and vitality regeneration in historic districts. |
