摘要
基于兴趣点(POI)数据,以街道为研究单元,利用DBSCAN空间聚类算法对西安市文化设施进行集群识别和等级划分,通过地理探测器量化分析西安市文化设施空间分布的影响因素。结果表明:(1)西安市文化设施空间分布不均衡,全类别文化设施具有明显的中心集聚特征;(2)各类型文化设施空间集聚程度不同,且受不同因素的影响大小不一,人口密度、交通通达性、经济水平以及旅游因素是其空间分布特征的主要影响因素;(3)所有因素两两交互作用均大于单个因素的作用,表明西安市文化设施的空间分布特征受多种因素叠加影响。
Based on POI data,this paper takes the street as the study unit,analyzes the spatial distribution patterns of cultural facilities in Xi’an City through the average nearest neighbor index and standard deviation ellipse,and uses the DBSCAN spatial clustering algorithm to identify clusters and grades of cultural facilities in Xi’an City,and finally,using geographical detectors to analyze the influencing factors of the spatial distribution of cultural facilities in Xi’an City.The results show that:(1)There are various types of cultural facilities in Xi’an City,the spatial distribution is uneven,and the overall has obvious central agglomeration and patterns;(2)Each type of cultural facilities has a different degree of spatial agglomeration and is affected by different factors.Population density,transportation accessibility,economic level and distance of tourist attractions are the main factors affecting their spatial distribution characteristics;(3)The pairwise interaction of all influencing factors is greater than the effect of a single factor,indicating that the spatial distribution of cultural facilities in Xi’an City is affected by multiple factors.
