Beijing Urban And Rural Areas Combined With A Country Park Space Layout Optimization

Country parks are located in the suburb of city, green space outside of these areas, it is a collection of the function of urban ecology and urban services, balance urban and rural development, maintain a reasonable city spatial structure of regional park. Country parks is characterized by: located at the junction between urban and rural areas, suburbs or recreational belt around; Less is given priority to with natural landscape, artificial landscape, is characterized by ecological, open; Objective in order to meet the demand of citizens’ leisure.With a rapidly expanding constantly eating away at the suburb of city and countryside land, destroy the rural ecological environment, urban pollution is serious, internal junction tourism development between urban and rural areas is becoming more and more attention. Based on the spatial layout based on the summary of the related theory, using GIS analysis and data statistics, analysis a total of44country parks layout of Fengtai district, Chaoyang district, Haidian district, the Shijingshan district, looking for recreation blind spots, optimize the first green barrier country park, provide the basis for the name of the second green barrier country park location.In the first, this paper summarized the theoretical basis, the layout pattern of urban and rural belt recreation facilities and influence factors, from whole to part, lay a theoretical foundation for country park layout optimization.Secondly, summarizes the development of England, Hong Kong and mainland China country parks, England and Hong Kong is the earliest area one of the most successful develop country parks in the world, the development of Beijing country parks, compared with that of found number of country parks, area and recreational benefits is a big gap.Third, focuses on analyzing the country parks spatial structure in Beijing, through the analysis of the overall layout, regional internal layout, traffic circle and standard deviation ellipse analysis, get the Beijing country park layout features: Space accumulation point distribution on the whole; Even regional distribution unbalance, the space was gathered layout; Country parks along the traffic trunk line distribution, the4th ring road and the5th ring road distribution density is highest; The overall band distribution, regional spatial layout direction is obvious. Then each area country parks contrast in the number, area, and somebody else’s country parks, analysis of country park scale hierarchy.Fourth, use of buffer analysis, comparing the distribution of population density figure and country parks, get the main factors affecting the country park layout are: clear on the population distribution, transportation and policy.Finally, through the GIS buffer analysis, superimposed analysis, network analysis, to evaluate the country park layout, and puts forward the existing problems: Overall population less country parks, the existing basic country park layout is in high demand areas, distribution unbalance, annular distribution, distribution and suburbs north outer country parks. Analysis based on GIS, and it is concluded that layout optimization, and put forward the optimization scheme:①reasonable planning, continue to intensify the construction of country park;②the first green barriers in the country parks cluster add small country park;③connect the existing cluster country parks and recreation, the production and the life comprehensive ecological area;④lack of country parks, outlying suburbs should be reasonable planning and construction of country park.
