Research On The Temporal And Spatial Changes Of Recreational Activities And The Influencing Factors Of Chengdu Residents

The urban recreation space is a systematicorganic whole that its development not only affects the change of urban spatial structure,but also affects the increasing leisure and recreation needs of urban residents.At present,with the rapid development of urbanization,people gradually pay attention to the transition from food and clothing to spiritual and cultural consumption.Meanwhile,the rapid development puts forward higher requirements for urban recreation space research and construction.As social media and location-based services(LBS)growing popularity,useing social media to study the behavior of urban residents has become possible.Microblog as an excellent platform for large data acquisition,not only the content,but also the geographical tag,can provide a rich source of data for the study of urban recreation space.Under the background of big data,through the qualitative and quantitative research on the urban residents’ recreation space,the paper expands the research ideas and methods of urban recreation space,and enriches the research content of urban recreation.Based on the study of the time and space law of urban residents’ recreation space,recreation theory,spatio-temporal data mining theory,grounded theory under the guidance of literature review,determined by cross quantitative research and qualitative research to analyze multivariate data fusion rules and influence factors of spatial and temporal recreation space of city residents.Taking Chengdu City as an example,we obtained the microblog data of Chengdu residents and the POI data of Scott map in 2014 and 2015,and analyzed the changes of the space structure and the spatial and temporal patterns of recreation space in Chengdu residents from the perspective of time and space.Through field investigation and interviews,we had access to the residents of the recreational activities of the law,and using Nvivo software coded the interview data,this paper analyzed the influencing factors of Chengdu residents’ recreation activities,and did some specific analysis of recreation space and the impact of the corresponding factors.The main contents and conclusions are as follows:(1)Affected by the influence of the urban circle structure,the change of the spatial pattern of Chengdu residents’ divergence is different according to the time division standard,and the circle structure is presented during the daytime,and the band is distributed at night.The difference between daytime and night is obvious.The density of residents’ recreation during the day is roughly in accordance with the law of "urban agglomeration-suburban decline-the weakest village".The core area is concentrated in Chunxi Road-Pacific and Sichuan University-Kehua North Road.The area with the highest density of residents in the night is Jiuyan Bridge-Tongzilin area,the middle of the formation of narrow activity-intensive areas.(2)The change pattern of the recreation space pattern of Chengdu residents during the week and weekend is different,the results showed the central gathering trend during the week,while the weekend presents the obvious "one heart and many points"characteristics.At time level,the number of microblog released by the residents showed"significant tail" distribution,and the number of weekend microblog is much more than weeks.At the spatial level,the week showed a multi-center agglomeration situation,specifically,the main city,especially in the Chunxi Road area as the core,north east of the East Street,south to Yulin South Road,west from Gaoshengqiao Road,east Jiuyan Bridge is the largest and most concentrated area in the urban area.It is the center of Chengdu residents’ recreation activities.The three core nodes are mainly distributed in Yanshikou,Chunxi Road and Kehua North Road.While the weekend showed a significant "one-hearted" gathering characteristic,Chunxi Road,the highest density for the concentration of the region and the rest are less than.(3)During the small holiday period,the change of Chengdu residents’recreational spatial pattern is mainly reflected in the interannual,from 2014 to 2015,the residents of the hot area in the space eastward shift.Within a year,Ching Ming Festival and Labour Day difference is not obvious,while the National Day and the Spring Festival during the college area significantly decreased.From 2014 to 2015,the core area of the residents’ recreation space in the past two years was significantly shifted eastward,and the heat in the south of the city was improved.In April 2015,the Pacific opening in the city of Chengdu,which has become a representative of Chengdu City shopping district.At the same time,Chengdu global center opened in 2013,the development path of Chengdu southward shift,the flow density gradually increased.It can be seen that the data of residents’ microblog is synchronized with urban development and residential recreation space,and it is feasible to study the behavior of urban residents with online microblog.(4)The spatial and temporal distribution pattern of the recreational space pattern of Chengdu residents showed three common characteristics:The diminished law of the circle structure;the hotspot areas of the activity were distributed along the traffic line;the Chunxi Road shopping district had the highest degree of aggregation.Specifically,the density of recreation roughly follow the "urban gather-suburban decline-the weakest law of the village." North-south line along the layout of the Chengdu City,many tourist attractions and commercial blocks,from north to south are:Wenshuyuan,Kuan Alley and Zhai Alley,People’s Park,Tianfu Square,Jinli Street,Wuhou Temple.Chunxi Road shopping district is a crowded shopping area,recreational heat in Chengdu residents in the highest concentration of recreational space forever.(5)The influencing factors of residents’ recreation choice,such as recreation activities,group contact,traffic,emotion and experience,local characteristics,history and culture,negative perception,and recreation activities are the most important influencing factors.Entertainment accounted for the highest proportion of 51.72%,while the remaining six categories of recreation reasons accounted for less than 10%.The entertainment,the frequency of eating accounted for 27.81%,reflecting the driving force for people out of the most common.At the same time,the reasons for different recreation space is also different,such as commercial recreation space corresponding to the recreation reasons are mainly recreation activities and local characteristics;historical and cultural attractions corresponding to the feelings and experiences,local characteristics and traffic;major colleges and universities corresponding to emotions with experience and local characteristics.There are two innovations in this research:First,the spatial-temporal distribution pattern of recreation activity is proposed based on the spatial distribution pattern.It is found that the recreation space pattern of Chengdu residents in the day is obviously different from the night,Chengdu residents microblog data during the day(6:00:00-2:59:59)showed a circle of decreasing law,but at night(3:00:00-5:59:59)showed a zonal distribution.Second,the comparative analysis is applied to the study of recreation reasons.Based on the perspective of recreation space,this study comparative analyzes the reasons of recreation and recreationl sites,and points out that the different types of recreation places are different from the reasons of residents’ recreation.
