GeoCA-Urban Model Study On Land Use And Land Cover Change In Peri

City, the center of human civilization, is creating huge fortune of material and inspirit, at the same time the development of city bring us many serious problems of environment. The land use and land cover change not only result in the change of ecosystem and ecoscape, but also affect the spatial structure change and the sustainable development of cities directly, and the abuse of city land resource become a large obstacle of urban sustainable development. In recent years, the land use and land cover change becomes a highlight of the Global Change Research and the land use and land cover change about city becomes one of most important focus.The spatial extension of urban is a process which has complex, multifactor, multivariable, uncertainty and dynamic characters, and to study the spatial change of city's land use and land cover not only need us to analyze the macroscopical conditions of city's development such as nature resource, economy develop and society change, but also need us to analyze the microcosmic rules of the city land use elements and their structure deeply. So it is necessary for us to use City Dynamics, Land Science, Geographical Information Science, System Geography and City Economics to study the characteristics and rules of city's land use and land cover change deeply.However, In the face of such a complex dynamic system, the traditional method...
