Land Potential Appraisal for Urban Land Reserve Based on GIS --A Case of Metropolitan Area in Chongqing

摘要

With the rapid urbanization, land banking has become an important means for rational land use and land configuration optimizing. Rational urban land reserve and supply plan are keys for an urban land banking. GIS has been used to model urban growth,growth at the rural-urban fringe specifically. The paper identified the urban land banking potential can be evaluated based on RS and GIS technology. 10indicators are chosen in the integrated index system.As a case of Metropolitan Area in Chongqing, urban land banking potential is evaluated based on RS and GIS technology. With GIS, two steps can help to finish potential analysis of land banking. One is goal driven process, i.e. the process of planning and definition; the other step is data-driven process, i.e. the process of Manipulating. The results are used to establish the current land banking plan.
