Study On Underground Space Integration Of Subway Station Area In City Central District

With the development of economy and society, the construction of the subway has been approved for 38 cities in China; we entered an important period of rail transit construction. City central district is the critical area of land use; subway construction can effectively alleviate the traffic pressure on the ground, promote the vertical development of station area, and bring new developing opportunities to the city center. But the lack of integration leads to many problems in subway station underground space. This paper tries to use integration concept and Environment-behavior method to finish a large number of case analyses and field research, and then propose integration design method of underground space in city central district subway station. It provides suggestions for future design of subway station.Traffic space and commercial space are two main underground spaces of subway station. Firstly, through the analysis of the characteristics and interactions of these two spaces, the article builds up an integration design framework. Base on this, seven cases in domestic or abroad are selected to analysis the integration method, and get user’s preferences. Thirdly, summarize the case study and revise the conclusion by population analysis, then get the integration design method of underground space in city central district subway station. Finally, put the integration design method into the urban design for the center area of Zhengzhou.
