The Theory And Practice Research Of Urban Cities'ecological Design

With accelerating urbanization and more serious environmental pollution, urban park attracts more and more attention as the important sector in the urban green system. Ecological design can effectively ease the ecological crisis and promote the city's sustainable development. And it is the nature trend of the development of urban parks. However, the theory of domestic ecological construction is still crude, and related regulation is incomplete yet. Rare successful cases exist in China. Consequently, this thesis is to discuss the principles, objects and methods of urban park ecological designing through analyzing the researching and designing methods of LIAN HU Park in QING LONG County based on the analysis of domestic and abroad urban park ecological designing development situation and related theories. Also, this thesis is to seek future of ecological gardening, and provide the theoretical reference and practical experience for urban park ecological construction.The main content of this thesis includes: 1. It summarizes the research progress of both domestic and abroad ecological designing theoretical findings, explains the meanings of urban park, ecological gardening and ecological design, concluding the designing principles (people oriented, respecting the nature, species diversity, 3R, taking actions that suit local circumstances) and discusses the value of environmental protection, economy and society which ecological design possesses. 2. According to the basic factors of urban park designing (including landforms, arrangement of plants, water body, roads, squares, creations, etc.), it separately concludes the ecological designing skills of every design elements in practice, which preparing for the specific cases. At the same time, it studies the implementation of ecological designing theories by analyzing two successful cases at home and abroad. 3. Taking the LIAN HU Park as example, through investigating the regional background, landform, construction situations and ecological environment, in the aspects of design concept, layout, function division, arrangement of plants and so on, it concretely assesses advantages and disadvantages of the specific designing methods, and puts up with some suggestions to city future construction and prospect.
