Study of Urban Land Optimal Allocation: A Case Study of Jinan

Urban land is the base for urban social and economic development. The variation of urban land-use structure brings different economic, social and environmental benefits to urban areas. At present, the land-use structures of most of the cities in China are, more or less, irrational. This has restricted the development of urban areas and the process of urbanization. For improving the level of intensive land-use, optimizing the structure of urban land and realizing the sustainable development of urban areas, this paper carried out a tentative study on urban land optimal allocation. Supported by RS and GIS, the suitability evaluation of urban land was implemented. And then, the optimization of quantitative structure of Jinan’s urban land was completed using a system-dynamics model established by us. Finally, the spatial allocation of Jinan’s urban land was performed automatically by a module developed using AML. According to the simulation results, the land use structure and the distribution of each kind of urban land use type will be optimized evidently, which is mainly characterized by the decrease of the land used to industrial production and its distribution shifted to the urban periphery. This paper integrated the AHP, systematic dynamics and land suitability evaluation with the optimal allocation of urban land use, which formed a framework for relative studies and have positive meaning to research of the pattern of land optimal allocation at the regional scale.
