Research On Spatial Renewal Strategy Of Existing Railway Station Boundary In Mountain City From The Perspective Of Catalyst

In recent years,China has paid more and more attention to the development of station traffic,and the construction of the station traffic complex with the traffic system has also been put on the agenda.However,under the development pattern with the station area as the core,it will often focus on the transformation and construction of the railway stations,while ignoring the development relationship between the station and the city.As an important area connecting the station and the urban living space,the railway station boundary space plays a good role in promoting the construction of the railway station and the construction of the urban space,and should be reasonably used and updated.Taking the boundary space of existing railway station as the main research object,applying urban catalyst theory to the renewal design of railway station boundary space,analyzing the railway station boundary space,selecting the breakthrough point and strategy of the boundary space,analyzing the railway station boundary space,selecting the breakthrough point and strategy of the boundary space renewal,so as to provide some reference for the resource integration and integration of railway station space and surrounding urban space.The core research content of this paper is as follows:In this paper,by consulting literature,starting from the theory of catalyst theory and boundary space,it conducts a more comprehensive analysis of its related concepts.By summarizing the research of boundary space from different angles,the definition and definition of boundary space of existing railway stations in mountainous cities are defined.The research scope,combined with the actual case of the catalyst theory in the space renewal,explores the applicability and necessity of the catalyst theory for the renewal design of the boundary space of the station domain,and lays the foundation for the guidance of the catalyst theory to the boundary space below.In order to further understand the specific problems existing in the boundary space of the existing railway station,as well as the subjective understanding of the intention and satisfaction of different user groups for the regional space,this paper uses the types,functional characteristics,and functional characteristics of the boundary space of the existing railway station in Chongqing Behavior and visual accessibility,to summarize the basic characteristics of the status quo,and through the classification and segmentation of the boundary space and the questionnaire satisfaction survey method,summarize the development problems and contradictions existing in the boundary space of the railway station,and understand the space of the site The main influencing factors and people’s tendency to this type of space,so as to use this as a basis to discuss the intervention of the following catalyst theory.Finally,in view of the existing problems,the catalyst theory is involved in the update of the boundary space,and the catalyst reaction process is constructed through four aspects:catalyst preparation,identification and selection of catalyst elements,modeling and activation of the catalyst medium,and subsequent guidance of the catalyst reaction.,And from the perspective of space,function,humanities and ecology,proposed a catalyst renewal strategy to enhance the boundary space of the station and transform the negative space of the city from the perspective of catalyst.Theoretical research needs to be confirmed by practice.After the theoretical research and summary,this paper uses the actual site as the basis to design and practice the Caiyuanba Railway Station,make full use of the catalyst theory and boundary effect,and strengthen the activation and opening of the boundary space of the railway station.Sexual design unearths the potential vitality space in mountain cities,and makes a certain contribution to the renewal and development of urban regional space.
