摘　　要：笔者通过改进先前提出的基于专家证据权重法的成矿远景区划与评价方法的不足之处,重新对青海东昆仑地区Au、Cu和Co3矿种进行成矿远景区划与评价,将各矿种的远景区按成矿潜力大小划分为A、B、C三级。在此基础上,提出了将多个单矿种远景区合成综合成矿远景区的评价方法和手段,最终圈定出青海东昆仑的综合远景区25个,并对它们也按成矿潜力大小划分为A、B、C三级。从青海东昆仑地区已知Au、Cu、Co矿床(点)在各综合远景区内的数量和规模分布情况来看,结果令人满意。青海东昆仑地区的综合选区研究成果可望为该区进一步找矿工作部署提供部分科学依据。The authors amended the ore prospect regionalization and evaluation method based on the Expert Weights of Evidence that were proposed previously by the author and re-delineated and re-evaluated Au, Cu and Co ore prospect areas in the East Kunlun region, Qinghai. According to their potentials, the prospect areas of these metals were divided into classes A, B and C, and on that basis, the authors proposed the methods for combining several single-metal prospect areas into composite ore prospect areas and evaluating these composite prospects. A total of 25 composite prospect areas were finally delineated in the East Kunlun metallogenic belt of Qinghai, and they were also classified into classes A, B and C based on their ore potentials. The results are thought to be satisfying according to the numbers, sizes and distributions of the known Au, Cu and Co deposits （occurrences） in various composite ore prospect areas in the East Kunlun region, Qinghai. The delineation and assessments of composite ore prospect areas in the East Kunlun metaUogenic belt, Qinghai, may provide a scientific basis for further arrangement of mineral prospecting work.
