GIS-based Layout Optimization Of Urban Green Space

Parks and urban green space system in urban public life is most closely components; to generally improve the standard of public services, parks, through the park system must be rational distribution. Construction of urban green space landscape early, as long as funding for construction, do not worry about green space and parks, after completion of services can not play or duplication of services; but a certain amount of urban green landscape from private houses into the evolution of urban green services , the scientific and rational layout is particularly important.With intuitive planners can not be a fair and equitable distribution of public green facilities, people eager to apply new theories and technologies to advance the existing planning mechanisms of green services, expand and improve the existing planning theories and methods. In recent years, with the industrialization and accelerating the process of information, "Digital Earth" concept put forward and "Digital City" that is holistic, project-oriented national strategy for the implementation of geographic information system (GIS) in our city planning application in the field of deepening; GIS technology "organic integration" in the urban public green facilities planning model will be an inevitable trend and research focus.This paper briefly reviews the development process of green parks and park systems in the formation, distribution methods; and comparative analysis studies, the Green Park System identified as public service facilities. Based on this, analysis of borrowing from other public service facilities layout methods using GIS technology, the possibilities. Secondly, the paper, the use of landscape ecology ("Inverse Planning" thinking) approach is to use the park system layout optimization Park layout based GIS; then using GIS in the Kriging interpolation method of spatial distribution of population in the region simulation and network analysis method and superposition method to calculate the scope of the park service. Several optimization method rely on each other, layer upon layer to promote its core is GIS network analysis. Network analysis to vector data - the road network as the basis for calculating the actual residents in the road time-consuming to assess the park services; to rational and efficient layout for the park system to provide a scientific basis. Once again, to Huaqiao International Business City, City Park system planning case study was conducted. Finally, a summary, and a bold prediction: the layout of the city park system will adapt to the times, with urban landscape east of Marxism, to the quantitative, information and systematic direction..Park system is the urban green infrastructure, science and reasonable layout of the park system not only has the protection of urban ecosystems, urban development to the healthy development of induced functions; and balanced to provide a comfortable and efficient urban green leisure space. To look forward to start a discussion of this article can play the role of writing, the layout of the city park system to provide a new method and new method, the layout of the park system to inject new vitality.
