Abstract

Abstract

The urban geo-environmental assessment is a basic prerequisite for the urban planning and site selection. In this paper, the urban geo-environmental basic database including topography, surface and bedrock geology, depth to groundwater table and corrosion potential, lithology of bearing layer, and historic geo-hazards is established, with the Lanzhou city in northwestern China as an example, on the GIS-based ARC/ INFO development platform. The urban land use is categorized as high-rise building, multi-story building, low-rise building, solid waste disposal, and natural conservation. The index system is systematically analyzed for the assessment of the coordination between various land uses and geo-environmental potential. Then the analytic hierarchy process method isemployed to establish the evaluation model for different land uses, and geo-environment potential foreach urban land use category isevaluated. The analytical resultsindicate that the combination of the GIS technology with the quantitative evaluation model can be applied to the fast and accurate assessment of the coordination between land uses for urban construction and geo-environment potential.
