西安市文化娱乐业空间结构图谱及其形成机理

Spatial Structure and Formation Mechanism of Entertainment Industry in Xi’an

文章利用西安市文化娱乐企业兴趣点(POI)和城市空间矢量数据,运用地学信息图谱理论,采用核密度分析和热点探测模型,探究城市文化娱乐业热点的广义对称结构与规模等级结构,揭示城市文化娱乐业空间结构形成机理。结果表明:(1)文化娱乐场所在西安市主城区总体呈现聚集分布特征,形成“内密外疏、南密北疏”和“多核心”的空间格局,在地理空间上具有显著的南北轴向和潜在的西南—东北轴向分布特点,各类文化娱乐场所大致符合总体布局特征,但是各自又具有一定的特殊性;(2)西安市文化娱乐业具有明显的空间对称规律与等级秩序规律,大型、较大型文化娱乐业热点在空间上呈现出轴对称、旋转对称和平移对称等模式,在横向上反映了城市空间的整体与局部结构形态,而不同等级热点区之间具有的等级结构和包含关系,则在纵向上表征了城市内部结构的规模等级特征;(3)西安市文化娱乐业空间结构是城市发展演变的阶段性与区域性的集中体现,文化娱乐业及其各业态空间结构的形成是城市物质空间因素、社会经济因素和消费分层因素交互耦合作用的结果,其中城市物质空间因素是重要约束力,社会经济因素是核心驱动力,消费分层因素是关键作用力。

Studying the spatial distribution law and influencing factors of culture and entertainment industry in big cities is the scientific basis for understanding the spatial interaction and spatial organization of urban culture and entertainment industry and promoting its optimal distribution. Based on the Geo-information Tupu theory and using the POI data of entertainment enterprises and spatial vector data in Xi’an, this paper explores the generalized symmetric structure and scale hierarchical structure of urban culture and entertainment industry hotspots,and reveals the influencing factors of the formation of urban entertainment spatial structure by the means of kernel density analysis, hotspot detection and geographically weighted regression model. The results show that: (1) The culture and entertainment industry in Xi’an downtown areas is characterized by aggregated distribution,forms a spatial pattern of "the high density in the center and the south, the low density in the periphery and the north" and "multi-cores", and have obvious north-south axial distribution and potential southwest-northeast axial distribution in geographical space. The spatial distribution of subcategories of culture and entertainment industry is broadly in line with the overall spatial characteristics,but shows some specificity. The distribution pattern reflects the development degree, function difference and development vitality across different spaces within city. (2) Culture and entertainment industry in Xi’an has obvious spatial symmetric law and hierarchical order law. The largest-scale and larger-scale culture and entertainment industry form the characteristics of axial symmetry,rotational symmetry and translational symmetry in space,which horizontally reflect the overall and local structural morphology of urban space. While the hierarchical structure and inclusion relationship among hot zones of different grades vertically represent the hierarchical scale characteristics of the urban internal structure. (3) The formation of the spatial structure of culture and entertainment industry and its various formats in Xi’an reflect the city’s development stage and regional characteristics. The formation of the spatial structure of culture and entertainment industry and its various formats is the interaction coupling result of the urban material space factors, socioeconomic factors and consumption stratification factors. Among them, urban material space factors are the important binding force, socioeconomic factors are the core driving force and consumption stratification factors are the critical force.
