Studies On Dynamic Changes Of Landscape Pattern Of Green Open Spaces In Wuhan City

With the accelerated process of urbanization, all kinds of ecological problems in the highlights, green open space has caught more and more attention. Urban green open space is an important part of the urban space structure as the city's ecological infrastructure. Urban green open space pattern is the space combination state between green open space and other space, as well as between various kinds of green open space, which is in a certain geographical area within the city. The quality of the pattern has a major impact on the running efficiency of urban. Therefore, it is necessary to study urban green open space pattern from a strategic perspective.This study takes Wuhan as an example, from the ecological point of view, discuss the evolution history of green open space of Wuhan City since the founding. This paper describes evolution model and the whole form Changes of the urban space and green open space within the various periods in detail, using qualitative and quantitative combining research methods; Wuhan green open space evolved along the basic model of space development such as core-hole, edge-eroding, the gallery space-cutting et al. Those evolution models appeared at the same time or alternately in the various stages. At the same time the layout of green open space changed the forms from the periphery to the wedge-style surround-chimeric then distributed.In order to judge the evolution course of the green open space more scientifically and objectively, author use the landscape index with clear ecological significance to reflect the evolution of green open space, and then identify the evolution rule of the green open space patterns in Wuhan City. The study found that: not only the area of all kinds of green open space reduced seriously, but also the form of the natural elements were growing regular , the landscape level index were on the rising level of fragmentation, of the lower connectivity.On this basis, author forecast the future pattern of urban green open space in accordance with the planning and relevant research about Wuhan City. Author found that if some department doesn't adopt strict control measures the green open space of urban development area will face serious threat. Further, author study power mechanism caused the evolution situation from several factors such as economic, policies.Finally, author proposed future restructuring and the direction of development of the green open space of Wuhan City from the dynamic perspective such as evolution and process et al.
