The Studies Owing To The GIS Of The Intensive Optimization Deploy Of Urban Land Resources

Urban Land is the basis of urban social and economic development, on its use of high and low level of urbanization will bring different economic,social and environmental benefits. The natural characteristics of urban land: the land of non-renewable and supply finitude; fixed location of the land; lack of congruity of the bearing capacity of the land; land-use sustainability. The economic characteristics of urban land: the scarce supply of land economy; land assets; location affect the value of the land, resulting in differential land revenue. The characteristics of urban land law: a piece of land can be derived from other legislative powers. Because urban land with the three characteristics, so that the land issue has become the world's eye-catching major problem. How to build the allocation of urban land use and intensive evaluation of the theory and its implementation through technical research objective,quantitative and optimizing is a hot one.To achieve optimal allocation of urban land, the land to a reasonable size, the best space organization and structure of land must be protection. Efficiency in the use of urban land is the comprehensive reflection of urban land optimizing allocation, the higher of the urban land optimizing allocation, the greater efficiency of urban land use. Intensive evaluation of urban land use in urban development is an appropriate size so that it was the largest gathering efficiency and effectiveness on the basis of mining layout of urban land use, land use, such as unreasonable structure of the causes, mechanisms and the number of potential to achieve higher economic, Social and ecological environment in the comprehensive efficiency and achieve the sustainable development of cities.Therefore, we can optimize the allocation of urban land use and intensive evaluation of integration - Intensive Optimum Location IOL is defined as: the theory of sustainable development as the guidance, based on regional characteristics of the city, at a reasonable scale for the premise, The pursuit of eco-living environment for the optimization objectives, through technical and economic means to optimize the urban land use structure, improve the density of urban concentration, to inform the judge or the city or urban land use of certain potential for the use of integrated (potential of the structure, quality potential, the potential suitability , The potential benefits, etc.) process.In summing up this paper at home and abroad advanced the theory, research methods and the investigation on the basis of a variety of data collection, in theory, methods, technology, empirical, and other aspects of urban land intensive optimizing the allocation of the content of the theory, technical line, Measures such as research methods and conducted in-depth research and the help of powerful GIS spatial analysis functions of Jiangxian optimizing the allocation of urban land intensive and the spatial distribution of a spatial pattern of innovation.
