Space Effectiveness Optimization Research Based On The Symbiosis Theory To The Campus-city Boundary Impact Realm

China's higher education has entered an important stage of mass education from the development of elite education.It brings great resources to all colleges and universities.There are 2914 colleges and universities in China to carry out formal records and enrolment,which influences urban form and function layout.The campus and the city are two different community networks,the two have different functional structure and material form,with different composition rules and spatial elements,as well as different historical processes and evolution laws,but with the background of the industrialization of education and the socialization of logistics,the closed management of the former walls and the cities can not realize the sharing of resources and the symbiotic symbiosis.Therefore,this paper introduces the concept of "boundary influence realm",and studies the influence range of the university on the city from the angle of boundary space.Based on the symbiotic theory,this paper systematically studies the symbiotic elements of the campus and the city from three levels of space:boundary line ontology,boundary line edge and boundary line.It is intended to find the law of this kind of symbiotic space.It provides theoretical support for the strategy of spatial transformation in the boundary area of university campus.In this paper,following background research--Conceptual Construction--spatial element--efficiency element--Strategy Construction--Logical deployment of design application:? Under the background of the urban spatial integration of the symbiotic theory,the problems of the school city relations are constantly emerging,and the relationship between the university campus and the city is studied by the space angle of "school city boundary influence realm",and the symbiotic elements and the Symbiosis Efficiency of the symbiotic theory are introduced into the space study to establish the relationship between the spatial factors and the spatial efficiency.? In the basic research of the symbiotic theory,the influence realm of the school city boundary,the emphasis is on the necessity and relevance of the research elements of the symbiotic theory and the theory of spatial aggregation and diffusion into the study of the boundary area of the school city boundary.In the light of the evolution and comparison of the school city interface between China and the west,the space and efficiency perspective of the boundary area of the school city boundary is explained,and the three elements of symbiosis in this paper are obtained:the open boundary line in the narrow sense,the design of the deep edge public places,and the promotion of the vitality of the generalized influence area.?Focus on the spatial composition and symbiosis condition of the influence area of the city boundary.Based on the "symbiotic theory",the symbiotic elements of the influence domain of the school city boundary are divided into three levels,which are boundary line ontology,boundary line edge and boundary line,and their morphological types and characteristics are analyzed in detail as the space carrier of the symbiotic model.Combined with the status quo of symbiotic unit,symbiotic mode and symbiotic environment,the paper investigates and summarizes the spatial elements of the paper.?The relationship between "symbiotic space elements" and "symbiotic space efficiency" is expounded.The symbiotic degree of the school city relationship is evaluated through the "symbiotic space efficiency",and the spatial elements of the boundary influence domain are corresponded with the "open efficiency,the marginal efficiency and the diffusion efficiency",and the evaluation factors of their respective effectiveness are set up to quantify the school city gate.The degree of symbiosis to the system.Finally,through the pedestrian counting and activity observation,the relationship between the spatial evaluation factor and the activity capacity is established,and the key factors that affect the living capacity of the two kinds of school cities in the new city and the old city are found,and the strategic suggestions are provided to optimize the space vitality.?Through the analysis of factors affecting the efficiency of symbiotic space and the combination of function and environment,the optimization strategies of open,permeable and diffusing three efficiency are constructed.So as to enhance the openness of the boundary of the city and the degree of vitality that affects the region.?Based on the research of the symbiotic elements,symbiotic efficiency and symbiotic strategy,the actual case-the eastern border block of the Xiamen campus of Huaqiao University,is introduced to analyze the opening degree of the boundary line,the thickness of the boundary edge,the spatial visibility of the realm,the development of format,and the walkability.We should carry out micro urban design on the three levels of boundary line,edge and influence area,and provide practical design and application for enhancing the effective implementation of the school.Through the study of this paper,a new perspective of the school city relationship,"the influence area of the school city boundary",is putting forward to study the corresponding spatial form and the internal relationship between the activity capacity distribution and the enhancement of the symbiotic efficiency.The optimization design strategy is put forward for the boundary space of different levels,in order to raise the opening degree of the boundary of the university garden and the vitality of the influence domain.The degree of force promotes the integration and symbiosis of the school city relationship.
