| With the rapid advance of urbanization process,cities are in the face of the reconstruction of job-housing space,and at the same time,it also faces the increase of residents’ commuting time or commuting distance,and a series of problems such as traffic congestion and environmental pollution as a result.Under the background of the new urbanization development,the residents’ expectations for a better life are constantly rising,then cities need to optimize the layout of the job-housing space,and improve the livable degrees of living environment and the convenient of public infrastructure.Therefore,it is of great significance to further clarify the relationship between job-housing space and commuting distance and enrich relevant researches in this field.This paper takes Wuhan metropolitan area as the research area,combines census data and network data,and studies the relationship between residents’ living environment and commuting distance in the study area.Firstly,the distribution characteristics of job-housing space are obtained through spatial analysis.The distribution characteristics of residential clusters change from"decentralized" to "centralized" with the increase of age.By contrast,the employment clusters change from "centralized" to "decentralized".The degree of job-housing balance in the urban area is much higher than that of the new town groups.At the same time,the commuting characteristics of residents in the study area are summarized.The commuting flows in Wuhan metropolitan area are mainly from the new town groups to the main urban area.Among them,19 to 29 year old residents account for 40%of the commuting flow.The commuting flows have significant proximity effect,and the largest source of commuting flows in hankou,wuchang and hanyang are from the western,southern and southwest new town groups.In addition,the average workers’ commuting distance decreases with age,the average commuting distance of 19 to 29 years old residents is 2.87 km higher than the 50 to 60 years old residents in main urban area,and the number in new town groups is 9.5km.Then,this research studies the relationship between the living environment selection and commuting distance of the 19-29,30-49 and 50-60 years old residents by using the multi-classification logistic regression model,the main conclusions are as follows:Firstly,the research studies the relationship of residential affordability and commuting distance.The results show that,long-distance commuters who live in the communities of higher price would suffer shorter commute distance.However,for the short-distance commuters,the correlation is not significant.Secondly,the research studies the relationship between the residential internal environment and the commuting distance of residents,and the results show that residents of different ages have different preferences for the residential internal environment.From the regression model of the residential building type and year of construction,for those residents who are in their twenties or fifties,if they are living in communities with singly multilayer buildings,and located in the old residential area,the probability of longer commuting distance for them is relatively lower.Thirdly,the research studies the relationship between the external environment that is public facilities accessibility and residents’ commuting distance,the results show that the communities whose accessibility of key schools are higher,the probabilities of long-distance commuting for their residents are higher.The primary schools have the most significant impact on residents’ commuting distance,and residents who are over 30 would be affected more by the accessibility of educational facilities.For other public facilities,large general hospitals are more concerned by the residents who are over 50 years old,they would like to select the communities with higher accessibility of large hospitals rather than closer to their employment locations to some extent.In addition,the accessibility of class A commercial facilities has the greatest impact on residents aged 30 to 49,while class C commercial facilities have the greatest impact on residents aged 50 to 60.At last,this paper summarizes the shortcomings of the research and gives a prospect for the future researches.This paper focuses on the relationship between the residents’living preferences and the separation degree of their job-housing space,and summarizes this relationship from the perspective of different age groups.Conclusion the residents’ commuting distance changes with the different choices of the affordability,internal environment and external environment characteristics of their communities of different ages.In particular,it has enriched the research on the relationship between the accessibility of different types of public facilities and the residents’ commuting distance. |
