The Characteristics And Efficiency Of Urban Park Recreation Network Based On Social Network Analysis

Along with the rapid economic and social development,people’s living standards have been gradually improved.Now that the material demand is basically satisfied,the people’s demand for the spirit culture such as the park,the recreation and so on continuously increase.At the same time,the perfect public transport facilities in the city have improved the travel ability of residents.A large number of new and reconstructed parks and greenbelts provide more choices for residents’ daily recreation.The recreation structure in the city is changing.However,the contradiction between residents’ demand for recreation and the supply of park green space continues to intensify.It is unknown whether the potential supply of park green space recreation services can meet the actual use of residents under the new background.This study uses the social network analysis method,from the perspective of systematization and Internet conversation,through the establishment of recreational structure network and functional network,to explore the potential recreational service supply of Wuhan park green space and the current situation of residents’ actual access to recreational services.By comparing the index differences between the recreational structure network and the functional network,this study evaluates the service efficiency of the park green space recreational network as a whole and the park individual.At the end of the study,in order to improve the service coverage,enrich the functional level of the park and improve the service efficiency of the park,the optimal layout scheme of park green space in Wuhan is put forward.(1)The research on the characteristics of recreational structure network shows that the completeness and relevance of recreational structure network increase with the expansion of park service radius.The ineffective points of parks in the recreational structure network are mainly distributed in the South and southeast of Hongshan District,the south of Hanyang District and the surrounding areas of East Lake scenic spot.These parks cannot provide recreational services for the surrounding residential areas.With the expansion of service radius,the scale of clusters in the structural network is gradually expanding,and the links within and between clusters are constantly strengthening.High weighted centrality nodes show a trend of local aggregation.Residents around Zhongshan Park,ink Lake Park,Hankou River Beach Park and Shouyi park can enjoy the services of multiple parks at the same time.The nodes with high weighted centrality and high school centrality are mostly comprehensive parks and amusement parks.Hankou jiangtan Park,ink Lake Park and Shouyi park often have high weighted centrality and intermediate centrality,and have high potential recreational services.(2)The study on the characteristics of recreational function network shows that the network integrity of the recreational function network of Wuhan park green space is low,and the invalid points are mainly distributed in the southeast of Hongshan District,the south of Hanyang District,the northwest of Qiaokou District and the north and south sides of East Lake scenic spot.In the functional network,high weighted centrality nodes gather locally,and the parks with the strongest service capacity in each cluster are still dominated by comprehensive parks.Ink Lake Park,South Trunk Canal Park,Wuhan Youth Palace,Northwest Lake green square,Zhongshan Park,Shouyi Park,Shouyi square and Xinhai Memorial square all have strong service capabilities in the functional networks under different travel modes.Ink Lake Park and Northwest Lake green square all show strong control capabilities in different functional networks.(3)The study on recreational service efficiency found that the service blind area of300m-1000 m network park green space is large,and the lack of park green space in the south of Wuchang District,the north of Jiang’an District,the middle of Qiaokou District and the south of Hongshan District is the most serious.In terms of service conversion rate,the service conversion rate of pedestrian network is much higher than that of driving network and public transport network.The public transport system construction in Wuhan has a low matching degree with the park and green space construction,and the urban transport system needs to be further improved.In terms of node utilization,the average value of node utilization of pedestrian network is much higher than that of driving network and bus network,and the difference of node utilization is smaller.
