Study On The Urban-complex Design Of Xi’an City Node In The Shaping Period Of Rail Transit

Xi’an in the process of rapid urbanization in recent years, urban expansion, the city is coated with the background. As the city structure of the existence of the pattern of large sites in Xi’an is facing the risk of being eroded, isolated, fragmented, resulting in the loss of urban memory. And this stage to accelerate the construction, gradually formed rail transit network, will lead to structural changes in urban space, urban landscape remodeling dynamic period. The site of the laying of the history of the city is concerned, is a new round of potential and opportunities. And urban complex as a modern city of high efficient, intensive symbol, is the preferred way of urban renewal. The urban complex as the starting point, the urban rail transit forming period of update problems and the pattern of urban history conservation issues hook even together to discuss under the premise of rational development, respect, highlighting the pattern of urban history, conform to the rail traffic has become the new trend of type phase node location three-dimensional, composite, create the thought and the way of the ideal city space environment.Firstly for such urban complex siting problem research, by rail transit network, the pattern of urban history and other urban renewal potential superposition, selected to highlight the problem of the specific lots and screened with lots of the concept of "urban node location" refers to, in order to emphasize the characteristics of the complex, contradictory stalemate. Then classify the selected node location from the lots in the development degree, lots of connecting rail traffic walking system conditions, historical role of architecture, urban renewal potential point of view, from a different point of view for the starting point of the design of urban complex. And pick out a more typical of the special case study of Tsing Lung temple area.In this design study, this paper puts forward that the design of this kind of urban complex needs to respect the two basic premise- the characteristics of the rail transit forming period and the pattern of Xi’an city.Based on rail transit molding characteristics. In this study discuss pathways for three-dimensional, composite trend of and the specific methods, in Qinglong Temple lot on location level using air Lianlang, underground ring corridor way combing streamline relationship. In urban complex level using sinking square, sky garden, roof garden, urban atrium etc. and level of urban public facilities connection; based on the characteristics of the pattern of urban history to discuss the specific methods of analysis and control of the relationship between the city, to pass design pattern comparison, on location level proposed application volume transfer design patterns, at the architectural level proposed monument type and landscape type city complex design mode, namely from the morphological point of mining highlighting the historical pattern.
