Research On The Spatial Reconstruction Of The Old Urban Area Of Changsha Under The Influence Of The Subway Construction

Subway stations as the core of urban rail transit channel is bound to make site surrounding area bring huge influence,become the new urban development catalyst,and produce certain aggregation effect,cause joint development of the land surrounding the site.For the old city,the development of the site surrounding area have to balance variety of interests,the development of the site surrounding area is more complex.Based on this background and the function partitions of general plan of Changsha city in 1990.The old city of Changsha City site is classified according to different functional properties,such as,residential site,commercial site,industrial site and historical and cultural features of the protection of the site.First,analyzing the status quo of the old city space before the subway intervention.Then respectively summarizing the old city of the current architectural form,space layout,traffic travel and other aspects of the characteristics and Analyzing the present situation of the old city space points from the summary.Finally,to provide the research basis for the influence of the old city after the intervention of the subway.Selecting the representative sites of all kinds of attributes as the research objects.To "TOD theory","urban catalyst theory" and "point axis system" theory as the theoretical basis.Depending on the spatial reconstruction after the combination of other various kinds of urban site and subway.After the intervention of Changsha subway,analyzing the influence of the surrounding area of the subway to the old urban area of Changsha in the space structure,space form,traffic grooming and other aspects.To provide the basis for the next step of the old urban space remodeling.Through the preliminary analysis and sum up the basic principles of the spatial reconstruction of Changsha old urban space under the influence of the subway.Combined with empirical cases,optimizing research site of remodeling space.based on the analysis of the influence of the subway to the old urban area of Changsha,optimizing space remodeling of the old urban area respectively from the space structure and space form,to solve currently problems of the old city space and activate the vitality of the old city space by optimization methods,to promote the mutual promotion of the subway and development of the old urban area.Then make the influence of the subway station to the old city of Changsha in the space form and spatial structure more clearly.a follow-up to the development of Changsha City in the vicinity of the site of the old city urban space provides inspiration and reference.
