Theory Research Of Urban Green Space System Planning Based On The Perspective Of "Pattern-Process-Function"

With the development of global industrialization and urbanization,we are experiencing rapid economic and social development.Cities as human populations,are important for human survival,life and production,but they are suffering a lot of problems.Smog,acid rain,water pollution and other environmental problems,such as loss of urban green space,the lack of landscape diversity and biodiversity and other ecological problems,which are gradually influencing our urban life.In the long history of urban development,people's understanding and demand for the city is growing with the evolution of the times,but the efforts of the people on how to solve the problem of ecological environment at home and abroad never stopped.Throughout the development history of the city ecological theory,the city as a complex ecological system,the systemic and complexity of which has gradually be taken seriously.The urban development process itself is a continuous consumption of natural resources,and constantly brings to the natural stress leads to the process of ecological risk.Urban green space system as the only natural ecological space,its composition,structure and process are important factors to decide the quality of city.These factors will participate in the urban space form,functions,organizations,landscape experience,safety control and other various aspects.This paper considers that the urban green space system planning method should be paid attention into the interaction between each subsystem instead of green space ontologies.First,this paper has carried on the literature review about the urban ecosystem and landscape ecology and urban green space system planning and other related content at home and abroad.And then it discusses the urban ecological system of organization pattern between each subsystem,and subsystem of the coupling relationship between material spaces.This paper emphatically studied the participation mode of urban green space system in the urban ecological system.What's more,based on the research of coupling model,this paper puts forward the planning research paradigm based on the perspective of "structure-process-function".Furthermore,we launch a study on the coupling relationship of urban green space system and other physical space subsystems of urban ecological system between different scales,based on the perspective of "structure-process-function".Bottom-up from micro,meso,and macro three dimensions,based on the perspective of "structureprocess-function",we study the coupling relationship between urban green space system,giving theory support to urban green space system planning method.This study thinks that: the macro scale of urban green space system for cities in regional ecological security to the structural support role,its expansion of urban spatial structure has played a key role;Medium scale in terms of urban green space system of urban central district with a skeleton link function,with the urban road system,water system,infrastructure,work together to promote the healthy development of the city;Micro scale of urban green space system and living space,commercial space and social cultural services facilities spatial correlation is larger,have obvious associated phenomenon between them.Finally,this paper will applied green space system planning theory based on the perspective of "pattern-process-function" in Kuqa urban green space system planning.According to the theory of pattern-process-function "method,we try to recognize objects,concept the plan,optimize the plan,deepen the plan,and apply it to the management.This study considers that the theory of landscape ecology can solve the problem of coupling between green space subsystems and other subsystems in complex urban ecosystems.First,we need to understand relevant theories,form the way of thinking,grasp the relationship between the structure,process and function,and have a whole grasp of the green space system in different scales.Second,we can make a choice through the analysis of landscape pattern analysis,sensitive area analysis,coupling evaluation system and other quantitative analysis.Last but not least,we need to make the planning more effectively play its ecological,social,economic and other service functions,through the cooperation between multiple class planning.
