Abstract: Abstract: Covering the metallogenic geological background, metallogenic regularity, prediction of mineral resources, gravity, magnetic, geochemical exploration, remote sensing, natural placer and other professional fields, The special research on China's mineral resources potential evaluation has gained huge amounts of achievements, and the amount of data has attained TB grade. The research and implementation of the integrated-database model of China's mineral resource potential evaluation, which integrates and utilizes the national basic data resource, constitute a very challenging task. The integrated-database model is foundation of building the mineral resource potential evaluation technology platform. The model aims to integrate the basic data and the high application, and also to link together the provincial, regional, national levels as well as maintain the proper functioning of the mineral resource potential evaluation at different scales. This paper systematically describes the integrated-database model of China's mineral resource potential evaluation and its concrete realization. This study has important practical significance and can play a guiding role in the national basic data resource construction.
