Abstract
In order to make rational use of geological resources; reduce the occurrence probability of geological hazards and environmental geological problems effectively; accomplish the coordination between functional layout and geological environment, this paper uses analytic hierarchy process (AHP) based on triangular fuzzy number to decide weight and sensitive factor evaluation model to evaluate the geological environment suitability in Zhongyuan Urban Agglomeration. Geological environment function regionalization is completed based on the evaluation results before under MAPGIS platform. Study result shows that geological environment functional region for basic construction land is mainly distributed in the regional city center within a certain radiant scope. The functional region for agricultural production land is mainly distributed in central hill region and eastern plain region of the research area. The functional region for environmental protection land is mainly distributed in northern and southwestern mountain region of the research area, as well as zones along the Yellow River and Middle Route in the South-to-North Water Transfer Project.
