The Open Space System Research Under The Background Of Rapid Urbanization

With the acceleration of urbanization and urban economic development, in the front of the economic benefit and social benefit and environmental benefits, People tend to be short-term interests of the drive and the economic benefit of choice. All kinds of buildings encroach on the limited city constantly space, People crowded in a closed cement building, and their Body and mind is constraints. As the"living room"and "green lung"in the city, the open space have improvement of the ecological environment, improvement of the image of the city, create livable space, providing residents leisure place function and so on. Therefore, The open space of the research work and construction activities have been concerned. On the other hand, the content related to the open space in our country’s current standard system Scattered in various regulations of standard. And there is lack of open space to separate systematic requirements. Hence, it is easy to cause the open space layout and construction practice of chaos. By analyzing and reference to a variety of standards and related research, and through the proposed open space outside the system is complete analysis, research ideas, this paper is good for the future of the planning, construction and which can be as reference.This paper mainly from the open space of the three aspects:characteristics of the overall,the levels and the function. The characteristics of the present situation of the general from the whole of the number, through the contrast of the standard and the relevant specification, put forward the deficiency of the current situation and the level. The study on the characteristics of the levels is from the system of the open space division level out, combined the research progress the home and abroad, established the reasonable level in the study of structure system. The characteristics of the function of the function structure is from the status quo of the organization Angle consideration, and the analysis is from the open space of the specific function and of various elements of the structure between the way, and its influence on the whole.The paper is divided into three parts and six chapters. The first part is theoretical construction and the related research reviewed, including the first chapter and the second. The main content of the first chapter is the study background and significance of this paper, and the general situation of the research idea and method. The second chapter of this paper is to study the foundation, including The relevant concepts, theory of correlation analysis of paper and research progress and practice. The second part, the empirical analysis of the open space system in Henan province Huaxian county enjoys the current situation and characteristics, including the remaining chapters. The third part is the conclusion.Based on the third, fourth, fifth chapter in the empirical study, the open space of Huaxian city in Henan province enjoys quantity is not enough, levels not clear, not perfect of the function problems. Through the open space county the analysis of the current situation, this paper are compared with the layout and urban overall plan of relevant schemes. Finally, the paper puts forward the county Huaxian city enjoys the open space layout optimization measures and Suggestions.In this study, this paper applied Arcgis software system and Arcview of many of the spatial analysis method. Combining with the overall urban planning of Huaxian city(2011-2030) about the road traffic planning, the green space system planning and other related content. Through analysis of the accessibility the space syntax analysis and tyson polygon analysis, etc, the paper integrated research and comparative demonstration about the open space layout. Try to putting forward a more reasonable and scientific layout scheme.
