摘　　要：本文从宏观上对中国的金矿床类型和时空分布规律进行了总结,指出了找矿方向。立足于中国金矿成矿地球动力学环境,以矿床基本地质特征为依据,对中国的金矿床进行了类型划分,阐述了8类独立岩金矿床地质特征。基于构造单元和地质演化历史对金矿床区域分布的制约,将中国金矿划分为5大成矿域、37个成矿集中产出区带,并总结了各区带的大地构造环境和相对应的金矿床类型。将矿床作为地质演化的历史指针来研究,把中国金矿床矿化时期划分为7个集中时期,并阐述了各成时期金矿化强度、主要金矿床类型及其空间分布规律。综合不同方法定量预测成果,认为中国未查明金矿资源潜力巨大,东部深部和西部还有很大找矿空间。简要评述了各个成矿区带找矿潜力,指出了下一步金矿找矿方向。On the basis of the distinctive geodynamic environment,gold deposits in China have been classified into eight types of rock gold deposit.According to the point of view that the tectonic unit and geological evolution control the regional distribution of gold deposits,the gold deposits of China have been devided into five metallogenic domains and thirty-seven metallogenic regions （belts）.the tectionic environment and the corresponding gold deposit type in each metallogenic region （belt） have been summerized too.Taking the gold deposits as a historical indicators for geologic evolution,it has been deduced that there are seven metallogenic epochs of the formation time of China＇s gold deposits,and then the metallogenic intensity,main types and spatial distribution of gold deposits in each metallogenic epoch have been elucidated.The results of different quantitative predictions indicate that China has tremendous potential for unidentified gold resource,especially in the west area and in the deep of the east area.Finally,a briefly comment on the prospecting potential for each metallogenic region （belt） and the future exploration directions have been made.
