Research On Spatial Pattern Generation Mechanism Of Urban Park Green Space Based On Synergy Theory

The development of urbanization brings about the recombination of land use structure in urban areas.This change will inevitably lead to the evolution of urban spatial pattern,and the spatial pattern of urban park green space is no exception.The change of urban park green space pattern has important influence on social economy and ecological function.Under the guidance of cooperative theory,this paper explores the theoretical basis of urban park system coordination,and proposes a collaborative planning method to maximize the comprehensive function of urban park system in the planning practice and optimize the spatial pattern of park green space.First of all,this paper summarizes the relationship between collaborative theory and urban park system,summarizes the idea of urban park green space system construction,and puts forward that the system cooperative operation mechanism is the theoretical basis,and the system collaborative planning method is explored under the guidance of theory.In this paper,the essential objective is to find the law of co evolution of the urban park system,to follow and optimize the endogenous rules in the system planning,and to construct the spatial pattern of urban park green space adapted to the urban development needs and the actual conditions.Secondly,from the point of view of the dynamic rule of the system operation,it summarizes the coordinated dynamic factors and operation principles of the urban park system.The dynamic factors include basic factors,economic factors,social factors and functional realization factors.These factors have direct driving force in the generation of space pattern of green space,and the principle of cooperative operation is explained by order parameter,feedback mechanism and domination theory.Then,the collaborative planning method of urban park system is constructed.The basic planning level of collaborative planning mechanism is expounded,that is,the four levels of urban park system conditions,elements,structure and network layout are optimized.The framework of collaborative planning mechanism is summed up in four steps.One is to analyze the environment conditions,construct the target of the system.The two is to select the components according to the requirements of the target.The three is the layout of the research elements,the construction of the subsystem structure,and the four is the superposition of the organization system,and the optimization of the spatial pattern.Finally,through the case study of the urban park system in Dangshan County,the formation process of the spatial pattern of urban park green space is analyzed,and the formation mechanism of collaborative planning is verified and practical planning.
