Study On Dual-Adaptation Evaluation Of Public Space Use Demand In High-Speed Railway Station Area Under Station-City Integration

Standing city fusion is based on the construction and development of high-speed rail hub,its core idea is to site area traffic function and city life function organic fusion in high-speed rail hub sites in the surrounding area(hereinafter referred to as the high-speed rail station),as the city space and high-speed rail hub site of cohesive zone,high-speed rail station intensive is bearing the weight of the activity of use main body diversification demand.Research from the point of view of the city integration,the systematic characteristic of high speed rail station public space,and under the perspective of complex adaptive system for high-speed rail station public space of the physical environment and use behavior associated mechanism for refining,emphasis on high-speed rail station public space and the demand for high-speed rail traffic purposes of high-speed rail traffic purpose use demand space two-way adaptation,It is a basic research of great significance to grasp the capacity of public space in China’s high-speed rail station area to provide high-speed rail transportation service and urban social life.Different from previous research methods that only focus on space itself,this study focuses on the needs of different users on the basis of the research on the physical environment characteristics of public space,and integrates human-oriented ideas into the development process of station city.Based on the integration trend of the development of city,this study systematically summarizes the high-speed rail station public space dimension of the physical environment and the use of subject dimension system characteristics,with the comparing of the seven characteristics of complex adaptive system theory coupling,to rebuild its physical environment is suitable for high speed rail station public space and the use behavior of the interaction between mechanism.By sorting out the development process of adaptability theory and introducing the "double adaptation" method,combined with the development trend of public space in urban high-speed rail station area,the characteristics of use demand of urban life mainly for high-speed rail transportation purposes and non-high-speed rail transportation purposes are summarized.On this basis,trying to build a multi-dimensional evaluation index system,the traditional coupling coordination degree model improvement for "double adaptive symbiotic subsystem-global system coordination" model,by using the evaluation model to carry on the empirical analysis,the system level in high-speed rail traffic purpose using high-speed traffic purposes of demand and demand classification of the partition of the evaluation results of contrast,Thus,the short board condition of factor layer that affects the symbiotic adaptation of subsystem is obtained.Based on the analysis of the evaluation results of the overall coupling and coordination level of public space,it is concluded that Guangzhou South Railway Station is at a barely coupling and coordination level,and such station areas need to attach importance to the planning and development of the overall space to promote the coordinated development of the overall public space.Beijing South Railway Station and Tianjin West Railway Station are at the primary level of coupling coordination,while Chengdu East Railway Station and Nanjing South Railway Station are at the intermediate level of coupling coordination.The public space of such stations should focus on the lack of adaptability to use needs for rectification and improvement,so as to achieve the purpose of better serving the public space with different needs.In order to accurately find and solve the problem of shortcomings,this study uses the obstacle degree model to diagnose the main factors affecting the double adaptation level of use demand in the station area,summarizes the main common problems at each system level,and puts forward corresponding optimization suggestions at the system level to improve the double adaptation level of use demand in the public space of the high-speed railway station area.The empirical results show that this model has the characteristics of dynamic and universal adaptability,easy operation and wide application.It provides targeted support for the continuous renewal and transformation of the public space of the high-speed railway station area,and also provides a new perspective and idea for the research of the public space of the high-speed railway station area,so as to promote the organic integration of the public space of the high-speed railway station area in China and the surrounding urban space.
