Research On Design Stratergy Of Subway Station Area In Cold Region From The Perspective Of Complex Adaptive System Theory

In recent years,under the guidance of the concept of sustainable development,the construction of "independent of car dependent society" has become one of the important issues of urban development.As a powerful guarantee to realize green travel,subway has been prosperous.As a new type of complex urban space,subway station space is an important link between subway and city.At the same time,the promotion of health awareness and the attention of relevant policies and regulations have demonstrated the huge development potential of China’s subway station space.Due to the limited outdoor activities in winter and other factors,the demand for the development of subway station space in cold cities is more intense,and has its particularity.However,at present,the space design of subway station area in cold regions in China is still in the stage of imitating and transplanting the experience of non cold region construction,lacking mature system and targeted strategy.As a complex and open urban space with multiple constraints and needs to be improved urgently,the cold subway station space urgently needs solutions to adapt to the multiple contexts of complex urban relations,so as to prov ide high-quality travel environment for residents in cold cities.Therefore,this paper attempts to introduce the complex adaptive system theory to examine the cold subway station space from a new perspective,explore the scientific design direction,and put forward the design strategy with guiding significance.Firstly,based on the analysis of the theory of complex adaptive system,this paper extracts the theory of complex cognition,co evolution and multiple adaptation with the adaptive subject as the core.Then,through the analysis of the relationship between the station space and the adaptive subject,and on the basis of analyzing the elements of the system and revealing the adaptive core of the main body,the cold Subway is constructed The optimization model of complex adaptive system with station space as the adaptive subject.Secondly,based on the theory and system deconstruction,the cold subway station space is replaced as the adaptive subject into the core idea.On the one hand,through multi-source information collection and the use of power By combining Bi visualization method and GIS analysis,this paper makes a complex understanding of the cold subway station space and its system;on the other hand,it uses AIPA method to analyze the co evolution mechanism and target of the cold subway station space and system;moreover,it uses SEM method to analyze the influence relationship between multiple adaptive functions and evolution objectives of the cold subway station space analysis.Thus,it establishes the optimization logic of system stock,which involves two dimensions of internal and external adaptation,including internal factors,external urban subject and external living environment,and constructs the spatial design framework of cold subway station area from the perspective of complex and complex adaptive system theory.Then,under the guidance of the design framework,three design strategies are proposed:In order to optimize the storage effect of system stock,this paper constructs the spatial BME cluster of cold subway station area based on word frequency statistics.It uses network analysis to infer regional scheduling rules,dynamic line tracking to infer path dredging rules,and node survey to infer origin destination organization rules.On the basis of these,the regional cluster,path cluster and origin destination cluster are constructed Three aspects put forward the integration strategy of subway station space in cold region;At the level of associating external urban entities,in order to improve the inflow probability of system stock,according to the subject characteristics of different interactive objects,the spatial pattern analysis is used to mine the coupling mode of domain and city,the cluster clustering relationship is used to mine the inter domain sharing mode,and the structural equation model is used to mine the field linkage mode This paper puts forward the collaborative strategy of subway station space in cold region;In order to reduce the outflow loss of system stock,this paper uses climate impact assessment to mine the original regulation mode,the perception situation to evaluate the field support mode,and the comprehensive performance evaluation to mine the change co creation mode.Based on the identification of the interaction dimension between the station space subject and the living environment,the paper uses the comprehensive performance evaluation to mine the change co creation mode The response strategy of subway station space in cold regio n is put forward from three aspects.The creative achievements of this study include:(1)introducing the theory of complex adaptive system,establishing the deep relationship between the cold subway station space and the complex adaptive system theory with the adaptive subject as the core;(2)using AIPA and SEM methods and taking the theoretical ideas as the deduction basis,the paper constructs the space design framework of the cold subway station area from the perspective of the complex adaptive system theory;(3)infers that According to the self adaptation rules of different BME clusters in the cold region subway station space,the integration strategy of coordinating its own elements is proposed.(4)The interactive adaptation mode between the subway station space and the external adaptive objects in cold region is explored,and the collaborative strategy and response strategy to avoid the living environment are proposed.The theory of cold region design is complemented by the theory of cold region design.The research ideas and methods proposed in this study from the perspective of complex adaptive system theory provide a new framework for understanding,analyzing and solving urban space design problems,which can be used for reference for similar design research projects.The spatial design strategy system proposed in this study provides basis and guidance for the development and constr uction activities around the subway in cold cities,which is conducive to improving the travel environment in cold regions,stimulating the vitality of cold cities and contributing to the sustainable development of cold cities.
