The Study On Comprehensive Benefit Of Land Use And Coordination Degree In Fuzhou City

Urban land is the spatial carrier for the production and the ways of life in the city, especially, urban land-use is the core of the urban construction. Along with city development and population growth, the issue of the land-use utility has been brought into focus. The urban land-use utility is the contrastive analysis of the input costs and output value of the land, it emphasizes not only urban economic benefit, but also social benefit and ecological benefit.Urban land-use includes three subsystems as economic benefit,social benefit and ecological benefit in the respect of system theory. This paper studies on land-use utility of Fuzhou city, moreover, analyzing the relation between input and output of the land. Based on the analysis of the degree of land utilization and present land market, analyzing the overall efficiency of land use in Fuzhou city by the multi-level grey comprehensive evaluation model,TOPSIS,hierarchical clustering analysis and grey correlation degree. The result indicates that:the overall efficiency of land use in Fuzhou city shows ascendant trend during 1998~2007. Then making a contrastive analysis of the coordination degree in the big cities by the modeling of coordination degree, it finds that: the coordination degree of land-use utility of Fuzhou city is above the mean level, it reflects that the urban land use of Fuzhou city is more reasonable.
