西安城市旅游休闲业态空间热点特征及形成机制

判识城市旅游休闲业态热点的空间规律,对于高效配置旅游休闲要素和优化城市功能结构具有重要意义。利用机构兴趣点(POI)数据,结合Getis-Ord G ^*指数等方法探究西安城市旅游休闲业态空间热点特征及形成机制。结果显示,西安旅游休闲总体业态热点区分别位于钟楼中心区、曲江-小寨区域和高新区电子城3个区域,各热点对应的业态集聚等级和空间尺度依次递减;与总体业态热点分布基本一致,各细分业态空间热点也主要集中在钟楼、曲江-小寨和高新区电子城等城市核心区。本质上,城市旅游休闲热点形成是由城市发展导向所决定的,即作为地理要素的城市空间在服务转型导向下,结合旧城改造与新区建设等城市核心区发展优化过程,对作为人文要素的旅游休闲业态施加作用,使其向城市核心区定向集中的结果。通过合理引导旅游休闲业态集聚发展,则可有效实现旧城区增长活力重塑和新城区空间品质优化。

Spatial Hotspots’ Characteristics and Mechanisms of the Urban Tourism and Leisure Industry in Xi'an City

It’s of great significance to identify the hotspot and its mechanisms of the urban tourism and leisure industry for efficient allocation of tourism leisure elements and optimization of the urban functional structure. Based on the data of industry interest points (POI), the spatial analysis methods such as Getis-Ord G* index are used in this article to explore the hotspots’ characteristics and their form mechanisms of the urban tourism and leisure industry in Xi'an city. The results show that for the comprehensive industry there are three tourism and leisure hotspots in Xi'an, namely, the Bell Tower hotspot in the center of the city, the Qujiang-Xiaozhai hotspot in the southeast of the city and the Electronic City hotspot in the southwest of the city. Meanwhile, there are inherent differences in the industrial agglomeration grade, scale and structure system of each hotspot. Similar to the distribution of the comprehensive industrial hotspots, hotspots of the subdivided industry are mainly concentrated in the urban core areas such as the Bell Tower, Qujiang-Xiaozhai and the city street named Electronic City. Essentially, the formation of urban tourism and leisure hotspots is determined by the orientation of urban development, that is to say, under the guidance of service transformation, urban space, as a geographical factor, exerts its influence on the humanistic factor, the urban tourism leisure industry, through the process of old city reconstruction and new district construction so as to make the tourism and leisure industry centralized in the urban core areas. By scientifically and reasonably guiding the agglomeration development of the tourism and leisure industry, the growth vitality of old urban areas can be rebuilt, and the spatial quality of new urban areas can be optimized effectively.
