Research On The Residence-Leisure Space Structure Of Shenyang Based On Travel Flow

Leisure is an important part of the daily activities of urban residents.The leisure function undertaken by leisure facilities and places is one of the main functions for all cities,thus the spatial distribution pattern of these facilities and places has also become an important part of the overall characteristics of urban spatial structure and layout.At the same time,due to a relatively dense flow of people will be generated between residential areas and large supermarkets,residential areas and highly popular parks facilities.These flows of people can reflect the characteristics of residents’ leisure activities and the spatial characteristics of urban residence-leisure functions,as opposed to static leisure facilities and places,it is a new perspective for the study of urban spatial structure.This study starts from the space of place and studies the spatial distribution of residential and leisure functions in Shenyang through spatial analysis methods based on the data of interest points,and forms a basic knowledge of the origin and destination characteristics of travel flows.Next,from the perspective of flow space,based on questionnaire data,points of interest and mobile phone signaling data,the leisure travel flows between residents’ actual leisure travel(residence-leisure),different travel purposes(residence-shopping,residence-park leisure)and different ages activity subjects(minor and middle-aged)are identified,thus the corresponding urban networks are constructed,residence-leisure functional relationship structure and the characteristics of different types of leisure activities of residents are explored from the perspectives of node strength,community structure,and source-sink distribution by means of complex network analysis methods.Subsequently,integrated space of place and flow space,based on travel distance,using inconsistency index and Gaussian two-step floating catchment area method to measure the matching relationship and accessibility of residential and leisure functions respectively,so as to explore the rationality of the organization of urban residential and leisure functions.Finally,the formation mechanisms of residence-leisure spatial structure is explored to provide theoretical basis and technical support for urban structure analysis as well as urban layout optimization and urban planning management.The results show that:(1)The residential and leisure functions have strong agglomeration characteristics in the central part of Shenyang.The residential function areas are mainly located in the north,southwest and southeast,and the leisure function areas are mainly located in the central and south.The number of streets with balanced spatial distribution of residential and leisure functions is small,and the residential and leisure functions are in an unbalanced development stage.(2)Residents’ leisure travel is characterized by centripetal agglomeration.The New North Station trade center and South Lake Park are the main places for residents to travel on weekends and holidays.The spatial characteristics of "one main and three vice" are shown in the scope of residents’ leisure activities.In order to achieve different leisure travel purposes,the residents’ shopping and leisure activity areas are mainly distributed in the north-south direction,and the residents’ park leisure activity areas are mainly distributed in the northwest,southwest and north-south directions.(3)The leisure activities of minor residents are concentrated in the business center within the second ring,and the degree of agglomeration of young and middle-aged residents for leisure travel is weak.In addition to the urban traditional business center,young and middle-aged residents mostly take leisure activities nearby.(4)The association structure of different types of residence-leisure networks in Shenyang reflects that the city has a single center sector structure,and the path dependence of single center development is serious.(5)There is a spatial mismatch between residential and leisure functions in Shenyang.The development level of the north bank of the Hun River is generally stronger than that of the south bank as a whole.The residents in the periphery often carry out leisure activities across regions.Residents’ leisure activities put pressure on the traffic inside the city,especially in the north-south direction.(6)The accessibility of shopping and park leisure activities of residents in the central part of Shenyang is high.There are a few areas with high accessibility in the periphery,and residents’ leisure activities are mainly of low accessibility.The leisure space in each trade center and along the Hun River belt can meet the leisure needs of minor residents.The configuration of leisure functions ignores the differentiated needs of residents of different ages,and there are fewer leisure functions that can meet the needs of young and middle-aged people to go out for leisure,and the supply of leisure functions exceeds the demand.(7)Leisure activity subjects have different leisure preferences,which influence the residence-leisure space for different travel purposes.Among them,female residents have a greater influence on the residence-shopping leisure space,and elderly residents and young residents have a greater influence on the residence-park leisure space.The number of facilities of leisure activity objects,especially the number of shopping and leisure facilities,has a strong impact on the residence-shopping leisure space.The number of bus stops has a strong correlation on residence-leisure space for different travel purposes.Travel distance has a weak impact on residence-leisure space for different travel purposes,and has a strong correlation with residence-leisure space for middle-aged people.(8)The relationship between residential and leisure function is an important part of urban structure,and spatial optimization strategies are proposed based on the spatial layout characteristics of residential and leisure functions in Shenyang to promote the healthy development of urban space.The residence-leisure functional relationship can make up for the limitations of the research on urban internal functional relationship,and it is a new attempt to analyze the intra-city spatial structure by constructing different types of residence-leisure functional relationship networks within cities through travel flow data.The study of the relationship between residential and leisure functional space by integrated space of place and space of flow can truly and reliably reflect the rationality of urban functional space layout,help to understand the law of urban development,and can be used as an important reference for the research of functional relationship within large cities.
