Research Of Urban Green Space System Planning Based On EI Theory In Fuyang City

The paper takes Fuyang city as an example to study urban green space system based on the ecological infrastructure(EI) theory. Based on the urban land use types and the different levels of development, Fuyang city urban landscape is divided into building land, transportation land, woodland, farmland, waters and other land etc. And the paper technical support to GIS and Fragstats, classifying interpret of the remote sensing image to get study area landscape type map.Firstly, analyzing the landscape pattern in Fuyang city, then six factors were selected to evaluate the ecological sensitivity, including land use type, slope, aspect, elevation, buffer zone of rivers and vegetation cover index(NDVI), ecological sensitivity was classified into five grades,that was extreme sensitivity, strong sensitivity, moderate sensitivity, slight sensitivity and non-sensitivity, the weights of the factors were calculated by using analytic hierarchy process(AHP). Based on the spatial analysis of geographical information system(GIS)and factors superposition analysis,the evaluation and the spatial distribution of overall ecological sensitivity in Fuyang city were achieved. The result showed that the ecological sensitivity in Fuyang city was very high generally, the area percentage of the five grades were 7.14%, 18.95%, 33.98%, 20.17%, 19.76%, respectively. Based on ecological sensitivity assessment, this paper classified three types of ecologically sensitivity region for urban planning and construction such as ecological protection area, control development area, suiTab. development area from the ecological security aspect. In summary, proceeding from overall regional landscape, identified the green space system planning layout of “one axis, three-core, two rings, four wedges, eight parks, multi-chain”.On the city scale planning, we construct urban green space system planning based on four urban ecological infrastructure systems: urban ecological water infrastructure, urban ecological core infrastructure, urban ecological access infrastructure, urban pests disaster infrastructure. In green ecological site design scale, three objects with the regional characteristic in the study area are special planning in details, providing the scientific basis for urban planning and construction in other places.Then, based on ecological infrastructure(EI) theory, the paper construct control planning and special studies from both macro and micro scale built-up area of Fuyang city. In terms of macro-scale, focusing on the urban ecological water infrastructure, urban ecology core infrastructure, urban infrastructure and urban ecological corridor mitigation infrastructure; at the micro scale, the focus research the typical of the type of ecological landscape elements in Fuyang city, including tat Fuchun river waterfront corridor, Huangwanggong mountain forest park and Xinsha wetland landscape elements. Three special planning and detailed will designed for landscape elements of the study area, providing models and scientific basis for urban planning and construction in other places.
