Study On The Early Warning Mechanism Of Urban Land Use Security In Wuhan Urban Agglomeration

Human depends on the land to survive and develop, while urban land use security is one of basic conditions for urban socio-economic sustainable development. The sustainable use of land resources is the foundation of the sustainable development of our society, so much as there is no sustainable development of the society without sustainable use of land resources. The urban land use security has to be taken into account during urbanization. This research on Wuhan Urban Agglomeration is vital to sustainable urban land use and socio-economic sustainable development in area, which is one of key points of the development of Wuhan Urban Agglomeration.On the basis of studying the current situation and obstructions of urban land use security in Wuhan Urban Agglomeration from 1999 to 2008, the paper applies the early warning theory with qualitative and quantitative research methods to study the early warning mechanism of urban land use security in Wuhan Urban Agglomeration. Including that: firstly, defining the concepts of warning condition which means defining the concepts of urban land use security in angle of sustainable use of land resources; secondly, constructing the early warning index system which contains warning condition index, warning source index and warning presage index; thirdly, dividing the different degrees of warning condition based on counting ten-years warning condition levels in Wuhan Urban Agglomeration; fourthly, analyzing warning condition by analyzing obstacles factors and concluding the major factors in Wuhan Urban Agglomeration from 2003 to 2008; lastly, on account of all above-mentioned, suggesting a series of measures to eliminate warning condition in Wuhan Urban Agglomeration.
