Study On The Development Strategy Of Beijing Green Space System Based On Construction Of Green Ecological Network

With the rapid development of urbanization, the global urban population is growing. The pressure of land, transportation and inhabited environment intensifies the conflicts between urban and rural areas. The urban environment capacity can’t meet the human’s needs. China is at a critical stage of urbanization. It is an unavoidable and important problem that we should face the conflicts between the ecological environment and urban construction. The subject of landscape architecture and urban planning should take the responsibility of bearing the important mission of urban inhabited environment and the ecological space development. Green space is the performance ensure of urban ecological safety and inhabited environment. The research of urban green space system is the key to settle the problem of urban inhabited environment. The idea of ecological network originates from the19th century. Green space ecological network derives from the extend concept of urban green space systematism, networking, greenway and etc. By now green space ecological network is widely applied in the green space systems organization and form a method to planning green space ecological network. At present, the concept of green space ecological network and the planning method is developing all the time. It is widely applied and practiced in some developed countries, such as Britain, America, Singapore and Japan. There are obvious effects in the controlling of disorderly urban expansion and dealing with urbanization problem.This dissertation illustrates green space system and its’network development with Beijing, which based on the research of the theory and practice of green space ecological network. By analyzing the typical urban case domestic and international on urban green space development, combining ecological network, the author summarizes the constructive method on urban green space ecological network theory thought. For Beijing, according to analyze the relationship of the Beijing green space ecological pattern evolution and urban morphology development, the study points out that the construction of green space ecological network is a effective new direction for urban green space system development, and provides the initial network plan of Beijing green space ecological network, it will guide the urban space development in Beijing correctly, to ensure local ecological security, improve the quality of living environment in Beijing. Hope to opens up a new directions and ideas for China’s urban green space system development, to guide China’s urban green space to holistic systematic, networked and efficient patterns of planning and development. And hoping this study can provide a theoretical framework and practical reference for the construction of Chinese urban green ecological networks. Here lists the main research contents and results.First, the dissertation draws a general overview on green space ecological network, differentiates and analyses related concepts and theories, defines the definition and connotation of green space ecological network and finally summarizes its’framework and function. According to the classical case on the evolution and development of green space ecological network of domestic and international city, the dissertation analyses the relation between green space of Beijing city and its spatial morphology, raises the question on China green space construction, points out the future city development direction towards green space systematism and network and finally provides referential experiences.Second, according to the contrastive study between the history of ecological pattern evolution and its’present situation, the dissertation points out the present problems of the ecological pattern of Beijing city, gives a analytic study on the green space structure of Beijing city and point out the existing problem in Beijing green space planning and construction at the present stage. The author also demonstrates the practicability and necessity of constructing green space ecological network in Beijing city and provides the ideal landscape ecological pattern and development needs of Beijing green space system.Third, based on the above research, the author summarizes the constructive method on green space ecological network. By using this method, the author emphasizes on the analysis of ecological node, ecological corridor, and network pattern of Beijing green space ecological network, and provides its’develop strategies. Under the guidance of theoretical method of green space ecological network, the author provides the initial network plan of Beijing green space ecological network. By using GIS, FFRAGSTATS technology and etc., the author gives landscape pattern analysis after the ecological space of Beijing city is networked. The author demonstrates the superiority of the plan and the rationality of the constructive method.At the end of the dissertation, the author discusses the future problem of Chinese green space construction development and draws a blueprint about the application and research work in urban green space field of green space ecological network. According to this research, the author hopes draw social attention on urban ecological environment problem and urban green space, and get social cognition on green space ecological network planning. The author also hopes to settle urban ecological safety and inhabited environment problems effectively by using this green space system development pattern-urban green space ecological network and finally realize urban sustainable development.
