Research On Urban Spatial Implantation Strategy And Pattern From The Perspective Of Complex Adaptive System Theory

The development of economic globalization has brought about the continuous expansion of urban scale.While people enjoy modern urban life,they must also think about the confusion and problems in the process of urban development.On the one hand,the rapid urbanization construction provides people with developed transportation system,comfortable shopping environment and efficient urban life,but on the other hand,the continuous accumulation and expansion of urban population,the deterioration of environmental quality,the destruction of urban space order and the loss of urban cultural characteristics have become great challenges faced by people in the process of urban development.So far,with the rapid development of urbanization in China,"urban design" has become a hot topic continuously discussed by Chinese scholars since the 20 th century.More and more scholars believe that the development of cities in China no longer needs to carry out large-scale urban expansion,and the overall improvement of urban space quality is the research focus of contemporary urban space development.In the face of many spatial problems and characteristics of urban development,the traditional design ideas and methods can not meet the needs of urban development in our country at present.We think that the research of urban spatial development should establish a comprehensive and systematic perspective and method to recognize and understand the urban space problem from a whole and systematic point of view,so as to promote the development of urban design theory.This paper studies the whole frame structure of the thesis composed of "phenomenon interpretation,theoretical research,concept proposal,pattern construction,practice test and design feedback".By using the research methods of complex system research,static analysis and dynamic analysis,and combining with the exploration of complex adaptive system theory and method,the complex adaptive system of urban space in China is analyzed and predicted.Based on the theory of spatial dissipative structure,this paper explains the essence and connotation of contemporary urban sustainable development,thus constructs the theoretical model of urban space implantation,and explores its application in practice.This paper mainly includes the following main contents:First of all,according to the interpretation of the present situation and problems of urban development in our country,this paper puts forward that the sustainable and vibrant urban life is the infinite driving force of the development of urban system.Urban development should respect the harmonious and unified relationship among the individual elements of the system,and realize the sustainability and vitality of the overall development of urban space by promoting the harmonious development of various individuals.From the perspective of complex adaptive system theory,it is considered that urban spatial system has the organic characteristics of life,the traditional urban design method can not effectively solve the advanced complex form problem of urban development,the understanding of urban spatial system problem is insufficient,and the solution is isolated and limited.this paper puts forward that a new interpretation should be carried out from the perspective of complex adaptive system to establish the whole view and organic view of urban spatial system.Second,according to the requirements of urban sustainable development,according to the mechanism characteristics of urban life,the concept of biological "implantation" is introduced,and the adjustment of urban function and spatial structure is achieved through the implementation of urban space implantation,so as to promote the self-organizing suture repair of urban cracks.The mechanism of urban space implantation is analyzed and the corresponding design strategies and principles are put forward.Third,according to the design principles,design strategy and the different types and characteristics of urban space implantation,the main spatial models of urban space implantation are systematically summarized,and the role and influence of systematic thinking on the evolution of urban space are further highlighted through case analysis.Finally,taking the actual case as the concrete practice,the practical problems and basic laws of urban implantation are studied and explored,and the development and design renewal of urban implantable in the future are prospected.In a word,the concept of urban space implantation is an effective way to think about the evolution of urban space system from the perspective of system science,conform to the dynamic evolution process and development model of urban system,emphasize the process of implantation and the corresponding feedback adjustment mechanism,and advocate sustainable urban development.The goal of urban space implantation is to establish systematic and orderly green,healthy and sustainable urban development,to achieve the return to people-oriented urban space design,and to advocate the high harmony of urban society,environment and economic development.As a possible shrewd development mode,urban space implantation systematically studies it and makes it a useful supplement to the theory of urban space evolution in the future.it is of great theoretical value and practical significance under the background of the transformation of urbanization from quantity to quality.
