The Impact Of Built Environment On Walking Behavior Of Residents

As a feature of modern urban development,informationization and motorization have made residents' work and life more efficient and convenient.At the same time,they have exerted a subtle influence on the lifestyle of residents.Sedentary and lack of physical activity have become the living characteristics of more and more urban residents.With the development of medical standards in China,chronic non-infectious diseases have replaced acute infectious diseases and become the primary threat to urban public health.The "Healthy China 2030" Planning Outline promulgated by China in 2016 emphasizes that health concepts should be integrated into the whole process of urban planning,construction,and governance.At the same time,walking as an important form of physical activity,with safety and convenience,can help people change the sedentary and physical activity lifestyle,reduce the risk of obesity,and help the physical and mental health of residents.The existing literature proves the feasibility of promoting the physical activity of residents through optimization of the built environment,but domestic research on this aspect is still in its infancy.Therefore,by exploring the relationship between the various dimensions of urban built environment and residents' walks,it not only has a certain disciplinary basis,but also an important breakthrough for the preparation of healthy urban planning,optimization of urban built environment,and promotion of “healthy China” construction.This paper presents a study to investigate the impact of the built environment of residential communities in large cities in China on residents' weekend walk behavior.Firstly,through the field research,this paper summarizes the socio-economic attributes and weekend walking activities of 3178 residents in 107 residential districts in Wuhan's main urban area,and explores the correlation between residents' social economic attributes and weekend walking.After that,this paper uses the objective metric method to calculate the six dimensions of 107 residential community built environment,including density,diversity,design,accessibility,bus convenience and green space coverage,and space for each dimension.Features were analyzed.Finally,this paper uses binary logistic regression and ordered logistic regression to test the impact of the six dimensions of the built environment on the weekend leisure walking and utilitarian walking probability and duration,and to distinguish the research conclusions from the existing literature.After that,this paper uses the objective metric method to calculate the six dimensions of the built environment of each community,including density,diversity,design,accessibility,bus convenience and green space coverage,and the spatial characteristics of each dimension are analyzed.Finally,this paper uses binary logistic regression and ordered logistic regression to test the impact of the six dimensions of the built environment on the weekend leisure walking and utilitarian walking probability and duration,and to distinguish the research conclusions from the existing literature.The main conclusions of this paper are as follows:(1)The influence of residents' socioeconomic attributes on walking is basic,and different types of residents have significant differences in walking behavior;(2)the effect of density on walking is different from that of Western countries.An increase in population density can promote utilitarian walking,but it will hinder residents' leisure walks;(3)The conclusions of design and destination accessibility support the conclusions of the existing literatures,and pedestrian friendly street design and high park area increase residents' walking activities;(4)Diversity,public transport convenience and greenfield coverage make the conclusions of relevant researches more refined.The diversity of POI facilities can promote residents' utilitarian walks,but an increase in numbers can hinder walking activities;The increase in the density of bus stations will promote the leisure walk,and the increase in the accessibility of subway stations will hinder two types of walking activities;For green space coverage,the residents' leisure walking activities are affected by the interior of the community and the buffer green space,while the utilitarian walk is mainly affected by the buffer green space.A green area with high coverage and low quality is a green space that is more suitable for walking.Based on the above conclusions,the following policy implications are obtained:(1)rational allocation of public resources to guide the population evenly distributed;(2)guiding the pedestrian-first,people-oriented “main block” construction model;(3)taking urban renewal as an opportunity to rationally optimize;(4)Optimize the supply of public transportation for the connection between the pedestrian system and the public transportation;(5)Increase the supply of green space in the central urban area and improve the form of green areas in the marginal area.
