基于网络爬虫数据的寒地大众体育建筑空间分布特征研究

Research on the Spatial Distribution Characteristics of Recreational Sports Buildings in the Cold Region Based on Web Crawler Data

以哈尔滨、长春、沈阳三个寒地城市为例,利用Python网络爬虫技术获取寒地大众体育建筑位置信息与类型信息,结合ArcGIS平台进行地理信息可视化,利用洛伦斯曲线及空间自相关分析等方法分析寒地大众体育建筑的数量分布特征及类型分布特征。结果显示:寒地大众体育建筑数量空间分布与人口分布基本拟合,但城市中心区空间集聚现象明显;寒地大众体育建筑运动类型具有聚集特征,易造成运动类型与运动偏好的供给偏差。这些分布特征反映了现有大众体育建筑规划设计中粗犷式的规划理念,并基于此提出提高区域内大众体育建筑规划精度与个性的策略调整建议。

This paper looks at Harbin,Changchun and Shenyang,three cities in the cold region of Northeast China,and utilizes the method of python web crawler to obtain the data of the location and type of recreational sports buildings.Combining with the platform of ArcGIS,the paper realizes the visualization of geography information.It also takes the method of lorenz curve and spatial autocorrelation analysis to analyze the quantity and type distribution characteristics.The results show that the quantity distribution of recreational sports facilities of the three cities follows the distribution of population,and the cluster phenomenon is obvious in the city center;the cluster phenomenon of type distribution is obvious,which can result in the difference between sports supply and sports demand.These distribution characteristics reflect the bold planning concept in the planning and design of the existing recreational sports building,and the paper puts forward adjustment strategies to improve the planning granularity and individuality of recreational sports building in the cold region.
