Research On The Restoration And Renewal In Ecological Landscape Of The Urban Lake

Water brings up the life and civilization of the mankind.In the colorful water environment of nature,the water is regarded as an important condition in the development and construction of city.Exploitation and use of the water are benefit to formation and development of the city.All kinds of water forms such as river,lake, ocean,deep pool spring,creek and the waterfall,have been integrated into the structure of city space and become the carrier which represents the image and culture of city.The urban lake is viewed as the rare natural resources of the city and the pearl of the urban water environment,however,in the process of urbanization,the ecological system of urban lake has been damaged enormously,and then,also affects on the visual image of urban landscape.Faced with the damaged ecological environment of lake,the restoration and renewal to the ecological system of lake continuously catch the eyes of the people and become the focus in the landscape planning of city.At present,many experts in landscape planning have paid not enough attention to systematical research of the restoration in urban ecological landscape.In this thesis, on the basis of analyzing the current situation of lake landscape and a lot of landscape projects in our country,many issues such as how to protect and exploit the source of lake and how to restore and renew the landscape,are discussed and researched deeply.(1)Analyzing general situation of lake resources in our country:researching urban lake influences on the urban development and construction,at the same time, discussing the influences on lake caused by the development of ecological tourism and the prosperity of "the green economy".(2)Defining what is the urban lake,the ecology,the restoration and renewal of landscape,and other important concepts and related contents to it.Putting forward theoretical research and its applications such as the landscape ecology,the restoration ecology and the landscape planning. (3)Analyzing basic issues of urban lake:relationship between water and city,the function and value of urban lake,the landscape elements and space environment of urban lake;pointing out some existing problems in the development situation of lake landscape,the rectification,reform and emergence of lake landscape in our country.(4)Making integrated research in the theoretical system of ecological restoration and renewal to landscape planning of lake,according to the existing problems in the current domestic construction of ecological landscape.Putting forward design concepts,design principles and methods in the restoration and renewal of ecological landscape of urban lake.Researching the strategies and methods in the landscape ecology,the restoration ecology and the theory of landscape planning and design through case studying.Taking the landscape conceptual plan of Wuhan city lakes as example to explain systematically how to apply those concepts and principles,and then,to find the feasible models and methods in the landscape restoration and renewal of urban lake.On the basis of it,regarding the lake as the research model,and inspiring the related research fields in order to lay the foundation for the in-depth research in the characteristics of landscape design,and to provide a reference for it.
