Abstract: So far, there are rarely any research which is the quantitative evaluation methods of mineral resources of all the counties in a certain province. In this paper, the evaluation model using the improved AHP integrated with fuzzy theory is established and this model is used to evaluate the selected 55 counties (cities) of Hunan province and the status of mineral resources of the counties are sorted according to the evaluation results. This method has not such large amount of calculations and the determination of the weight of the coefficient is not such subjective as traditional AHP. The results show that most of the counties are of the middle level and there is a big gap between the counties. The evaluation results are in consistent with site survey results which indicate the model and the method is applicable and can be a reference for quantitative evaluations of mineral resources of counties in other province. The indicator system is divided the subsystem in each layer is evaluated individually which can obtain an evaluation result in each subsystem. The counties can determine what strategies should be taken according to evaluation results of the layers and this can let counties make the development decision more scientifically.
