A Study On The Spatial-temporal Land Use Change Of Urban Fringe

Urban fringe is the foreland in the process of "urban sprawl", especially in developing countries e.g. China. The rapid land use changes in this transitional and semi-urban system often puzzled urban researchers.Firstly, the historic trajectory and driver system of urban fringe's development are summarized. Then a spatially explicit model named CLUE (Conversion of Land Use and its Effects) and a "process or behaviour" model named DPSIR (Drive-Pressure-State-Impact-Response) are introduced. CLUE model is designed to obtain insights into the complexity of the land-use situation as well as to explore and quantify near-future pathways of land-use development. And DPSIR model can explain the cause and effect relationships between interacting components of a complex social, economic and environmental system.In this research, CLUE model is developed to understand the land use change of Hongshan District, the fringe of Wuhan city, China. After the possible factors underlying every kind of land use type were identified with the help of DPSIR model, the significant factors influencing the land use change were found out through the logistic regression model. Then the land use patterns of Hongshan District from 1996 to 2010 are simulated and the possible scenarios are generated for different alternatives. It will support the planning decision greatly.At the end, some conclusions and recommendations are made which are supposed to be helpful for future study.
