【摘要】 目的 揭示宝鸡市健身设施空间差异和可达性现状，为宝鸡市健身设施合理配置、空间规划布局提供指导和建议。方法 结合宝鸡市健身设施POI数据、县域人口数据、夜间灯光指数、交通道路数据以及DEM数据，采用标准差椭圆、核密度分析、平均最近邻分析法、地理探测器等方法，研究宝鸡市健身设施空间分异格局以及可达性。结果 (1)在健身设施数量方面，渭滨区、金台区与眉县比例较高，分别占健身设施总数量的15.54%,14.79%与14.04%。千阳县与麟游县占比最低，均为2.06%;(2)宝鸡市健身设施分布在沿长轴，并呈现“西北-东南”分布，具体为城区密集、郊县稀疏，沿河汇集、离河分散的趋势特征；(3)宝鸡市健身设施总体空间分布不均，具有南北稀疏的分布特征，呈现市中优于郊县、中北部优于南部的集散现状；(4)宝鸡市健身设施的空间分布类型为集聚型，健身设施可达性高，而位于城市边缘地区的健身设施可达性不足，健身设施分布存在城乡差距；(5)人口密度、夜间灯光指数对健身设施的空间分异影响较大，河流水系对健身设施的空间分异影响较小。结论 宝鸡市体育健身服务设施存在显著的城乡差距，需对其设施布局进行优化提升。更多还原

【Abstract】 Purposes—To reveal the spatial differences and accessibility status of fitness facilities in Baoji City, and provide guidance and suggestions for the rational allocation and spatial planning layout of fitness facilities in Baoji City. Methods—Based on the POI data, county population data, index of the light at night, traffic road data and DEM data of fitness facilities in Baoji City, the spatial differentiation pattern and accessibility of fitness facilities in Baoji City were studied by using standard deviation ellipse, kernel density analysis, average nearest neighbor analysis and geographic detector. Results—(1) In terms of the number of fitness facilities, Weibing District, Jintai District and Meixian County had the highest proportion, accounting for 15.54%, 14.79% and 14.04% of the total number of fitness facilities respectively, while Qianyang County and Linyou County has the lowest proportion, accounting for 2.06%;(2) The fitness facilities in Baoji City are distributed along the long axis, showing a "northwest-southeast" distribution, which is characterized by dense distribution in urban areas, sparse distribution in suburban counties, intensive along the river and disperse away from the river;(3) The overall spatial distribution of fitness facilities in Baoji city is uneven, which is characterized by sparse distribution characteristics in the north and the south of the city, and better distribution in the city and the north than that in the south of the city;(4) The spatial distribution type of fitness facilities in Baoji City is agglomeration. The accessibility of fitness facilities in Baoji urban area is high, while that in the urban fringe area is insufficient, reflecting the gap between urban and rural distribution of fitness facilities;(5) Population density and index of the light at night have a greater impact on the spatial differentiation of fitness facilities, while river system has a smaller impact on the spatial differentiation of fitness facilities. It is expected to provide guidance and suggestions for the rational allocation and spatial planning of fitness facilities in Baoji City, so as to achieve the purpose of comprehensively improving the national physique and health level, and make practical contributions to the basic construction of a national fitness system with Chinese characteristics. Conclusion—There is a significant gap between urban and rural areas in Baoji’s sports fitness service facilities, so it is necessary to optimize and improve the layout of its facilities.更多还原
