Research on the Correlation between Commercial Diversity and Urban Vitality in Historical and Cultural Cities Based on Big Data: A Case Study of Jianshui Ancient City
-
摘要: 多样性是城市的天性。城市空间形态、功能业态的多样性与城市活力的相关性是城市规划研究的一个重要领域。对于历史文化名城来说，保护与发展的矛盾日益突出，一方面要维护原住民的日常生活，另一方面又要发展旅游，如何平衡两者是个关键问题。本文以云南省红河哈尼族彝族自治州建水历史文化名城作为研究对象，在古城与紫陶文化产业园区的两大片区范围内，运用手机信令数据表征城市活力、POI数据分析商业业态特征，探索历史文化名城业态布局与城市活力的关联性。通过研究发现：业态的多样性与城市活力的时空分布并非完全正相关，业态的品质才是决定其吸引力的重要因素；而跳出古城发展更有活力的旅游新区是平衡古城保护发展矛盾、避免“活着的古城”被景区化的有效路径之一。Abstract: Diversity is nature to cities. The correlation between the diversity of urban spatial forms and functional formats and urban vitality is an important issue of urban planning research. For historical and cultural cities, the contradiction between conservation and development has become increasingly prominent, and how to balance the maintenance of the daily life of the indigenous residents and the development of tourism is also a crucial issue. The research uses Jianshui historical and cultural city in Honghe Hani and Yi Autonomous Prefecture of Yunnan Province as a case study. In the ancient city area and the purple pottery cultural industry park area, the mobile phone signaling data is used to represent the vitality of the city and POI data is used to analyze the characteristics of commercial formats, to explore the correlation between the commercial formats and urban vitality. The research finds that: the diversity of commercial formats is not entirely positively correlated with the spatiotemporal distribution of urban vitality, while the quality of commerce is an important factor of its attractiveness. On the other hand, the development of a more vibrant new area of tourism growth outside the ancient city is one of the effective ways to balance the contradiction between the conservation and development of the ancient city and avoid the 'living ancient city' being a merely scenic area.
