Urban Rail Transit Site Area Of Outer Space Morphology Research

Since the late90s of last century, China started construction of urban rail transitcontinues to this day, and in expanding domestic demand, increase investment ininfrastructure to address the global financial crisis and the larger environment bestrengthened. At present, China has entered the city rail transit construction of highspeed growth, while also reflects the prosperity of the city rail transit and cities in thespace environment, use, transport, sustainable development, and so many problems.Urban rail transit has been involved in space, improve the accessibility of urban spacearound the site, leading to the functions of cities within the region to re-layout of theoriginal, and the results induced the evolution of urban space around the site, aprocess that the original performance of rail transit interaction between urban spaceand integration.Papers selected site for the rail transit center,500meters as the radius of acircular area as an ideal object of study, and define it as the site area; in accordancewith the rail transit site to the region’s main land feature on the site for the type of railtransit division, that is centered site, city-based sites, residential sites and attractionsand community-based sites into four categories. In this paper, the site outside theregion of space as the research object, to outer space, the elements summarizedSquare Park, building interfaces, pedestrian system and road transport system,through domestic and international case studies and analyzed the different types ofrail transit stations of the land area and external space environment utilization, andthe type of site regional centers and residential areas between community-orientedsite, a comparative analysis of rail transit and to explore the integration of the existingurban space.Areas of urban rail transit stations morphology of outer space, the purpose is notlimited to rail transit and to understand the interaction between urban space, but alsobecause the elements of urban external space to grasp the essential characteristics, sothe author from the full text of the final step behavior-oriented point of view,proposed regional rail transit sites to guide the design of external space to the cities ofChangsha City rail transit construction and play a constructive role.
