Abstract: On the basis of previous studies，the paper states the status of Chinese classification for mineral resources and reserves (Chinese Classification)，scope of its application，and debates and problems of its application.The paper also introduces briefly the status of the United Nations framework classification for fossil energy and mineral reserves and resource in 2009 (UNFC—2009)，the purpose of preparing it，and the idea of its classification.Through comparative studies of the objective，stress，and intension of the two classification systems，the paper gives similarities and differences of UNFC—2009 and Chinese Classification.Based on the mapping，the paper gets the following conclusions：the E axis and the F axis of the two classification systems do not correspond.But they can correspond from classes；UNFC—2009 that has outstanding commercial features doesn't fit Chinese condition.So when we revise Chinese Classification，we cannot follow it directly；Chinese Classification has outstanding features that it can be effectively used to classification of mineral resources.However，when we revise Chinese Classification，we need to focus on harmonizing the function of the conversion from mineral resources to mineral reserves.
