Abstract: Urban recreation space is an important organic part of a city,and its development is a reflection of not only the urban socioeconomic culture,but also the evolution of urban spatial structure.Based on Baidu POI data,using Ripley’s K function,spatial autocorrelation,and the nearest neighbor hierarchical clustering analysis methods,this paper studied the spatial characteristics of public recreational facilities in Urumqi City,Xinjiang,China,summarized the patterns of urban recreation space,and explored the influencing factors of urban recreation space.The results show as follows: (1) The spatial distribution of the leisure facilities in Urumqi shows a marked centrality and agglomeration. (2) The hot spots of the six kinds of recreational facilities show different tendency of agglomeration.The entertainment facilities,shopping facilities and sport facilities tend to cluster near important transport hubs and commercial centers.The hotspots of catering facilities show obvious population orientation.The hot spots of tourism facilities are all located near hot scenic spots.The hot spots of cultural facilities are located in the mixed ethnic areas. (3) The recreation space pattern in Urumqi is displaying a “layer+ sector + group” mode.The city center is the planar comprehensive leisure center,and the periphery of the city center is the fanshaped leisure facilities area with low density,grouped multifunctional leisure area and grouped catering leisure area.The suburbs have few leisure facilities but are grouped tourism leisure areas. (4) It is proved that the recreation space of Urumqi is positively correlated with the spatial distribution of population.
