Research On Spacio-temporal Characteristic And Influencing Factors Of Residents’ Leisure Activities Based On Multi-source Big Data

With the improvement of urban economic level and the development of residents’ diversification,urban residents’ work time and work location are becoming more flexible,and the Engel coefficient of residents has declined,and leisure activities and places have gradually become an important part of residents’ life and work.In the study of the daily activities of urban residents,especially in the study,the questionnaire data has always been the main research basic data.This thesis is based on domestic and foreign scholars’ research summary of urban leisure activities and leisure space.Exploring new urban resident activities research methods-ie urban multi-source data represented by mobile phone signaling data as basic data,using Arc GIS space analysis,database The combination of the extraction query and other techniques,identify and analyze the spatial and space characteristics of urban residents’ leisure activities and their influencing factors.First,according to the context of urban leisure activities and leisure space,the casual space and resident leisure activities of Nanjing Central City are identified;the special space distribution,aggregation characteristics,preference selection from leisure activities,research the specific residents’ leisure activities Features;Finally,analyze the influencing factors of resident leisure activities.With the density of street leisure activities,the number of leisure activities in the leisure function node is the research variable to resident relevant factors,road traffic related factors,leisure facilities,urban land related factors,and leisure function point-related factors to interpret variables,construct geospatial Weight,using regression analysis,spatial metering model,etc.,compare the influencing factors affecting the spatial distribution of residents’ leisure activity under different studies.According to the above research content,the following main research conclusions are obtained:(1)The casual land in the central city of Nanjing has differentials in the spatial layout of the old city and the old city,and the size of the outer area of the old city is small but the spatial continuity is strong,the plot of leisure land land outside the old city is divided into scale.Large,in different municipal jurisdictions,the core-scattered dotted spatial structure is present.The nuclear density of the residents’ leisure activities in the central city,the spatial distribution characteristics of the active hotspot area are similar to the spatial structure characteristics of the leisure land,and the active high-strength area is gathered in the old city adjacent to the old city and has a high coverage.Different regions aggregate nucleation.(2)In the leisure activities of residents,the number of casual activities in commercial services is the highest,and the activity intensity hotspot is concentrated in the old town and the old city marginal area.The number of new street business districts is the highest and in the casual function node.The first level is extremely high,and the attraction of the commercial deputy center is large.The number of casual activities in the park Square is second only to commercial service,but the hotspot area of the overall activities is also concentrated along the Xuanwu Lake and the ancient city wall of the old city,the residential area of the old city,street square,etc.The emergence of all active hotspots can be upgraded to the public leisure places such as park green space,squares such as population density,resident attributes.In the central city,the spatial distribution of cultural sports land has formed a "one-core multi-point" spatial structure,but the number of recreational activities of cultural sports and low activity is low,and the overall activity is low and the activity space is distributed.Discrete,and the attractiveness of the core area of the cultural strength.insufficient.The leisure activities of the scenic spot are concentrated in Qinhuai scenery representatives represented by the husband Temple in the old city.This feature may be related to the weather,temperature,season and other external factors of the activity data collection.(3)There is also a difference in the influencing factors of the spatial distribution of leisure activity under different studies.In the city street level,the streets themselves with the neighboring streets,the transportation site density,leisure facilities(POI),and urban land hybrids will have a forward influence on the density of the street leisure activity,which can be used to optimize these forward influences.Factors to enhance the strength of the streets.At the central city level,the attraction and service capability of the core and nodes of the city level,partition-level leisure function is to plan the target,including but not limited to the increase in the number of transportation sites,increase the number of casual facilities,and increase leisure The area of the type,enhance the degree of leisure land mixing,and the special service function of the leisure node is enhanced.
