Reserch On The Strategy Of Xi’an City’s Affordable Residential Space Layout Based On Rail Transit Construction

Affordable housing is a major initiative to improve the urban low-income housing for needy families living conditions, Xi’an is now in rapid development stage of the construction of affordable housing. The author with the protection of Xi’an settlements issue investigation found that, under the impact of urban land market, resulting in more affordable settlements located in the lower land prices in urban areas, while the lower land prices in the region are distributed urban fringe, so that the presence of settlements in Xi’an affordable space layout marginalized large, uneven distribution of the characteristics of the characteristics of this layout is often accompanied by a lack of public services and jobs, thus bringing medical care, education, employment inconvenience insured population be forced to travel long distances to meet the basic needs of their lives, but also due to the lack of public transport facilities, increases the cost of their travel and time costs, seriously affecting the efficiency of the security of affordable housing. Xi’an recent years to develop rail transportation as the backbone of the public transport system, rail transit is a large-capacity, fast public transport, and its development to expand the space of the city, and brought to the outskirts of the city population and industrial organic evacuation, accelerate city center, the development of the Metro group. Urban rail transportation in addressing aspects of long-distance travel compared to conventional buses have significant advantages. With the continuous expansion of urban space, increasing the travel distance of urban residents, so more and more people tend to choose to live in the rail transport sphere of influence, however, the research found that the protection of existing settlements and rail transport in rarely associated with spatial distribution, at this stage rail travel for low-income people are less effective. Based on the above reasons, it led the author to the protection of settlements, combined with rail transit site layout thinking, also contributed to the research objective here.The main body of this paper is divided into six sections. The first part, the paper selected at the end of 2015 the main city of Xi’an has built affordable rental-type settlements as a research object, the pattern layout of affordable public housing building settlements successful example of Singapore, that transit-oriented development mode for the next phases of the settlement Xi’an affordable residential space layout plight provide a reference. The second part, the article summarizes and reviews the development history of Xi’an protection of settlements and the construction of rail transit and the size and characteristics of their respective results analysis of spatial distribution. The third part of the affordable housing in Xi’an insured population characteristics were summarized, combined with research data, analyze the current situation in Xi’an affordable settlements layout gap between the insured population needs, and affordable residential space to the layout factors are analyzed, and predict the spatial layout of Xi’an, the protection of settlements further marginalization trend. The fourth part analyzes the correlation between Xi’an protection of settlements and rail traffic situation layout, draw its existence time and space coordination, rail transit and bus adapter inappropriate questions. By analyzing the rail has a significant advantage in addressing security issues of settlements, combined with rail transportation for the protection of layout settlements necessity and feasibility are described. The fifth part summarizes the advanced experience of Singapore’s public housing combined with the layout of the status quo to protect settlements in Xi’an, from security policy and strategy research two proposed combination of rail transit development of affordable residential space in Xi’an solve the plight of the layout implementation strategy: in terms of policy, the government recommends that the impact can be developed within the scope of a unified land reserves and land supply and the protection of settlements into urban rail transit construction plan for rail transport. In the layout strategy, first, combining residential clusters priority construction of rail transit on the 8th(Link); second, the "conventional rail + bus + community bus" mode of transport; third, be made within the scope of rail transport TOD the method of construction mode. The sixth part of the research results were summarized and discussed with the lack of prospects. In this paper, the principle of the protection of the spatial distribution of settlements and forward-looking perspective Study guide rail affordable residential space layout deepening in theory, give full play to the advantages of the role of rail transport in urban development, and guide the protection of reasonable settlements layout, solve the housing problems of low-income populations fundamentally, to achieve sustainable development of cities.
