Study Of The Urban Landscape's Constitution,Planning And Designing

Urban landscape ecology, one of the researches on landscape ecology, focuses on the research of ecological process and special structure of urban landscape, urban ecological environment and it's relationship with landscapes'elements, and landscape ecological planning and designing, ets. Urban greenland system, as the main style of urban landscape, plays a very important part in maintaining and improving ecological environment. It is the core of the research on urban landscape ecology.The article, taking Jinhua as an example, combining the basic theory of landscape ecology, conducts a research on landscape ecology in urban greenland system. It has practical instructive significance and reference value for the landscape ecological construction in our country, which is being urbanized now.The research mainly contains the following chapters.The first chapter introduces some theories on landscape ecology and urban landscape ecology, and briefly analyzes the meaning of landscape ecology in urban greenland system and the significance of it's research.The second chapter is about the natural and economical condition and the process of the urbanization in Jinghua.The third chapter first analyzes the ecological and environmental problem rising from the urbanization and its nature, and the landscape ecological problems prevalent in present cities. And then it focuses on the analysis of the change of landscape ecological structure and it's environmental effects.The forth chapter mainly explores the classification of landscape ecology in urban greenland system and specifies the greenland landscape styles applied in the research. And on basis of this it verbally analyses the characteristics of urban greenland landscape ecology in Jinhua and the main problems exist.The fifth chapter, choosing a proper index of spacial structure and landscape fragmentation in landscape ecology, quantitatively analyzes and evaluates the present landscape ecological structure in Jinhua urban greenland system.The sixth chapter is the focus of the research. Basing on analysis and evaluation of the urban greenland system planning of Jinghua urban general plan(2000~2020), combining the main problems exist inthe present greenland system and applying the theories of landscape ecological plan and design., it supplies a superorised plan and explores the landscape designing of urban Greenland with specific cases.At last the article draws several conclusions, confirming that the landscape ecology theory can offer a general usage in the urban greenland landscape ecological construction, especially emphasizing the application of nature-superiority principle and the consistence principle of landscape ecological structure to the greenland landscape plan, suggesting that various landscape design planning can enhance the special nature of the landscape of the urban greenland system in Jinhua, thus help to develop a reasonably distributed, well functioning landscape ecological system with local characteristics.
