POTENTIAL EVALUATION AND EXPLOITATION DIVISION OF THE DRINKING MINERAL WATER RESOURCES IN HUNAN PROVINCE

Hunan Province owns abundant and high-quality resources of natural drinking mineral water. This paper adopts the evaluation factors of regional geological condition, hydrogeological condition and mineral water resources situation to build an assessment indicator system based on analytic hierarchy process and evaluate the potentiality of the drinking mineral water resources by the compound evaluation index model. According to the evaluation results, 11 high potential areas, 14 potential areas and several medium and low potential areas are divided. On the basis of resources potential evaluation, with market potential and economic and technical conditions for development and utilization, the province is divided into prior exploitation areas, main exploitation areas, prospective exploitation areas and restricted exploitation areas.
