Research On Design Of Public Space Around Subway Entrance Based On Catalyst Theory

Subway,as one of the most important public transportation in the city,has been gradually introduced by big cities and become more and more important because of its large passenger traffic volume,high efficiency,low energy,consumption and space-saving.Besides its own transportation,the connection and development between subway itself and surrounding area seems comparatively important.Subway has brought huge crowds,and subway station becomes a node in the region by gathering and distributing the crowds where has the effect of radiation and activation to the surrounding urban environment so as to promote urban development area by area.In order to make this article clearer,this article focuses on the public space around the subway station.In this paper,the relevant concept of catalyst theory is introduced.I intend to find a new mode for public space in the vicinity that suitable for the city through the study of catalyst theory.The first chapter is the introduction part.The article firstly established its research purpose on the basis of giving a simply narrative about the present situation of the development of the urban subway.Then outlining the catalytic theory concept,analyzing the research status at home and abroad and putting forward to the structure of the thesis by presenting the research scope,research methods and content.The second chapter mainly introduces the theoretical support-urban catalyst theory.The catalytic effect of the subway to the city has been put forward from three levels by analyzing the excellent examples from different angles at home and abroad.The third chapter mainly discusses the current situation of subway station of Shenyang.Different analysis of catalyst,line catalyst and dot catalyst have been carried out to the completed subway station of Shenyang.At last,the analysis results are obtained through the SWOT analysis and the site analysis of different peripheral environment.The forth chapter discusses the potential catalytic site of metro line 9 based on the catalyst,line catalyst and dot catalyst.So,the corresponding design method has been put forward to each kind of catalyst.The fifth chapter mainly describes the design practices of Shenyang metro line 9 of different environments based on catalyst.Thanks to the support of catalyst theory,and the analysis and solutions of chapter 3 and 4,the metro line 9 site has been selected and design practice of surrounding space has been done.
