| 研究城市中体育场地的空间分布对于改善城市空间布局、促进城市体系自我优化和健
康发展具有重要的理论和实践意义。运用DBSCAN空间聚类算法和ArcGIS空间分析工具对长沙
市主城区体育场地空间布局进行分析，运用地理探测器对其影响因素进行定量分析。研究结果表
明：（1）长沙市体育场地在空间上表现为集聚且具有梯度等级效应，呈现出中心集聚、四周分散的
特征；（2）长沙市体育场地被划分为分属5个不同等级的17个集群，噪声点零散分布；（3）长沙市体
育场地空间异质性是不同影响因素共同作用的结果，其中小区核密度、人口密度及经济发展水平
影响较大。最后基于研究结果，提出了长沙市体育场地优化选址建议。 |
| 英文摘要: |
| It is of great theoretical and practical significance to study the spatial distribution of sports venues in cities for
improving the urban spatial layout and promoting the self-optimization and healthy development of the urban system. In
this paper, the main urban area of Changsha was selected as the research object, and the spatial layout of its sports venues
was analyzed by using DBSCAN spatial clustering algorithm and ArcGIS spatial analysis tool. And the influencing factors
were quantitatively analyzed by using the Geo-detector. The results show that: (1) The sports venues in Changsha are clus⁃
tered and have a gradient effect in space, showing the characteristics of "being central gathered and scattered around"; (2)
The sports venues in Changsha have been classified into 17 spatial clusters belonging to 5 different levels, with the scat⁃
tered distribution of noise points; (3) The spatial heterogeneity of sports venues in Changsha is the result of the joint action
of different influencing factors, among which the community core density, population density, and economic development
level have more significant impacts. Finally, based on the research results, some suggestions on optimizing the site selection
of sports venues in Changsha were put forward. |
