中国大城市旅游休闲业态的空间格局研究：西安案例

明确大城市旅游休闲业态的分布规律对于提高大城市旅游休闲要素配置效率及完善城市现代服务业体系具有重要意义。本文以机构兴趣点（POI）数据为基础，利用最邻近距离指数、核密度估计及地理探测器等空间分析方法，以西安市为案例探究中国大城市旅游休闲业态空间格局的规律性。结果表明，西安城市旅游休闲总体业态和细分业态均表现为在城市中心局部多核集聚，且业态密度由城市中心区向边缘区梯度递减的分布结构。而这一规律实则为消费市场、CBD区位、经济水平和路网密度等因素综合作用的结果。文章认为，为提高大城市旅游休闲产业要素配置的均衡性与高效性，城市管理者需兼顾城市中心及外围区域的统筹发展，并应在消费引导、资本投入、功能区建设和基础设施优化方面加大对外围区域的支持力度。

SPATIAL PATTERN AND MECHANISMS OF THE TOURISM AND LEISURE INDUSTRY IN CHINA'S BIG CITIES: A CASE STUDY OF XI'AN

It is of great significance to clarify the distribution pattern of urban tourism and leisure industries for improving the allocation efficiency of urban tourism and leisure elements and optimizing the modern service industry system in big cities. Based on the POI data, the distribution pattern and contributing factors of urban tourism and leisure industries in Xi'an were explored by using the analysis methods such as the nearest distance index, the kernel density estimation and the geographical detector. The results showed that the urban tourism and leisure industry of Xi'an is characterized by multi-core agglomeration locally in the urban center, and the density of the industry is gradient decreasing from the urban center area to the marginal region. While, this regularity of distribution is the result of the comprehensive effects of the market, location, economy and transportation factors, in which market factors are the core driving force, CBD proximity and economic level are the key driving force, and traffic conditions are the supportive driving force. According to the article, to improve the balance and efficiency of the allocation of tourism and leisure industry elements in big cities, city managers should take into account the overall development of urban centers and urban peripheral areas, especially the support for consumption guidance, functional area construction, capital investment and infrastructure construction in urban peripheral regions should be increased.
