摘要: 为准确理解都市圈跨城通勤者择居行为、优化都市圈融城空间结构，以长株潭都市圈为案例，建立融合多源数据的择居 偏好分析及融城空间格局识别模型。利用多源数据提取跨城通勤基础特征及驱动因子，探究跨城通勤现象的空间分布 特征；建立最优参数地理探测器模型，量化分析各因子对跨城通勤者居住地选择的影响机制；建立基于谱聚类算法的都 市圈城市融城功能区识别方法，评估并优化都市圈空间格局发展。结果表明：（1）长株潭都市圈跨城通勤者居住地分布密 度呈现南集聚北分散的多核心特征。（2） 不同维度建成环境、经济等因素对跨城通勤者居住地选择的影响程度不一，其中 区县GDP、距市界距离、小区均价、商业消费指标为核心驱动因子。（3）长株潭都市圈融城格局划分为6类功能区为最佳。
Abstract: To accurately understand the residential choice activities of intercity commuters and optimize the integrated urban spatial structure, this study takes the Changsha-Zhuzhou-Xiangtan metropolitan area as a case study. A model is developed to analyze residential preferences and delineate integrated urban spatial patterns by integrating multi-source data. It employs multi-source spatial data to extract the basic features and driving factors of intercity commuting. The study delves into the spatial distribution patterns of intercity commuting phenomena. Furthermore, an Optimal Parameter-based Geographical Detector (OPGD) model is established to quantify the impact mechanisms of various factors on the residential choices of inter-city commuters. A method for dividing the functionality of urban integration in metropolitan areas based on spectral clustering is also established to evaluate and optimize the spatial pattern development of the metropolitan area. The results show that: ①The distribution density of intercity commuters' residences exhibits a multi-core characteristic, with agglomeration in the south and dispersion in the north. ②Factors such as spatial environment and economy, across different dimensions, exert varying degrees of influence on the residential choices of intercity commuters. Among them, district GDP, distance from the municipal boundary, average housing prices in residential areas, and commercial consumption indicators are identified as the core driving factors. ③The optimal division of the urban integration pattern identifies six categories.
