City Park System Research Based On The View Of System Theory

With our in-depth study of urban green space, Urban park system become widelyattention because of its natural, holistic and comprehensive. Our country has muchpopulation,but limited green area,so how to coordinate the layout of the various typesof green space to maximize the benefits of urban green building has become a seriousproblem.Urban park system is a complex organic wholeness which has manyelements,multi-level and versatility.It contains rich content and covers a wide range ofcomplex planning steps. If there is no scientific and systematic methodology to guide, itis difficult to achieve as a function of their overall play. With the introduction of systemtheory into urban park system planning, complex as a whole by being divided from thecommon link in understanding them out, then part of the foundation in theunderstanding of all aspects of organic tissue will be up to become a whole, in order tobetter understand the whole,you can effectively guide the planning process to promotethe realization of the overall maximum functionality and improve the utilization of thelimited green space.First,from the system point of view, this paper defines the concepts of systemtheory and urban park system, reviews the study process of them，and obtains the urbanpark system planning research objects which are based on the system point of view.These research objects are elements, structure, function and system of Urban parksystem which play a very important role in clearing the planning process andmaximizing the over all function.Second, this paper discusses the concrete application ways which are about thebasic principles of system theory in urban park system planning. Its main principlesinclude integrity, level of theory and optimization theory. The paper discuss the relevantplanning cases which are based on the system point of view, summarize these basicprinciples of ecological network planning of urban park system inspiration so as toeffectively guide the ecological network of urban park system planning process.Again, based on the analysis of the theory and practice of the previous pape,thepaper discusses the concrete application of urban park system under the basic principlesof system theory,and then,it makes a preliminary exploration of planning ideas andplanning methods of system-oriented urban park system,and the specific process can besummarized as according to the status, sure planning objectives-combin with planning objectives,select ments layout various elements, planning structure-subsystemoptimization, construct the system super position,in whew the target is the basis ofecological network planning.The target is decided by the city’s natural and geographicalconditions,historical and cultural conditions of urban construction and urban parksystem planning profiles and other factors. Typically, the target is not a single plan,according to the basic ecological network of urban park system functions can be dividedinto landscape,recreation,ecological and historical inheritance, four sub-goals,and thefour sub-goals correspond to the landscape subsystem, recreation,ecological andhistorical inheritance subsystem sub-system. The elements of different target are alsodifferent,they have an important influence on the structure and layout of urban parksystem, specific elements of the structure in accordance with a different layout with aspecific function that can be combined into a subsystem.On the base of thesub-structure superimposed,the paper takes of optimization analysis to arrive at acomprehensive ecological functions of urban park system.This paper takes archicaloptimization method, respectively, from the macro and micro levels of the greenstructure adjustment and optimization of ecological networks.Finally, the paper takes the Yuzhong district as an example，responsed to theproposed planning theory，explores and researches the planning process of Yuzhongurban park system and the way of maximizing the realization of function based onsystem theory.Linking theory with practice, this paper preliminarily tries to combine the systemtheory and urban park system planning, and explore the planning method. It proposesnew ideas and new views of urban park system planning, which is a reference of otherrelevant planning.
