摘　　要：矿床品位—吨位模型研究属于学科前沿领域,它是系统勘查理论的重要组成部分。依据"97年全国矿产储量数据库"资料,对全国27个大型—超大型铜矿床建立了地质模型、品位模型、吨位模型、吨位—品位联合模型、以及中国斑岩型铜矿床吨位序列模型。模型类型包括频率直方图、累积频率分布图以及双对数坐标表示的理论分布模型。分别总结了中国大型超大型铜矿床的品位及吨位分布的典型数学地质特征,并探讨了吨位—品位模型在资源预测评价中的意义和作用。The study of the grade-tonnage model of deposits is a frontier subject and an important component part of the systematic exploration theory.The authors have established the geological model, grade model,tonnage model and combined grade-tonnage model for 27 large and superlarge copper deposits and a tonnage sequence model of porphyry copper deposits of the whole country,according to the 'National Mineral Reserves Data Base,1997'.The model types include frequency histograms, cumulative frequency distribution graphs and theoretical model with double logarithmic coordinates. The authors have summed up separately the typical mathematical geological characteristics of the grade-tonnage distribution of large and superlarge copper deposits of China.The paper also discusses the reliability and predictive function in the mineral resource evalution with Zipf's law and the tonnage sequence model.
