基于多源数据的兰州城市活力空间分布及影响因素研究

Influencing Factors and Spatial Distribution of Urban Vitality in Lanzhou Based on Multi-Source Data

中国的城市正在从高速发展转向高质量发展,城市活力受到人们的广泛关注,但西北地区的城市活力研究成果十分有限。研究基于兰州市基础地理数据及网络开源数据,通过构建城市活力量化指标体系及城市建成环境多维度测量指标体系,分析了兰州市城市活力的空间分布特征,运用地理探测器模型分异及因子探测、交互探测两个模块分析建成环境影响因子对城市活力的影响程度。结果表明兰州市城市活力存在分布失衡、活力欠缺等情况并且受到城市建成环境的多因素影响,研究成果以期为兰州的城市规划和资源配置提供建议及参考。

Chinese cities are shifting from high-speed development to high-quality development,and urban vitality is receiving widespread attention.However,research on urban vitality in the northwest region is very limited.This study is based on the basic geographic data and open source network data of Lanzhou City.By constructing a quantitative indicator system for urban vitality and a multi-dimensional measurement indicator system for urban built environment,the spatial distribution characteristics of urban vitality in Lanzhou City were analyzed.The factor detection and factor interaction detection modules of the geographic detector model were used to analyze the degree of impact of built environment factors on urban vitality.The results indicate that the urban vitality of Lanzhou City is imbalanced and lacks vitality,and is influenced by multiple factors of the urban built environment.The research results aim to provide suggestions and references for the urban planning and resource allocation of Lanzhou.
