摘　　要：文章以MATLAB技术为平台,以西藏自治区雄村铜矿床为实例,详细讨论了如何开发以克立格理论为基础的固体资源储量估算系统,其中包括模块:数据预处理、变异函数分析、克立格估值、储量估算、地质可靠度评价等。论文使用该系统对西藏自治区雄村铜矿床进行储量预测,得出结果数据表格;并对原生矿体、次生矿体、氧化矿体、总矿体、矿体的自然形态以及在工业品位规范下的矿体形态进行拟合。通过与专业储量估算软件M ineS ight的估算结果对比,证明了本系统的可靠性和实用性。The Xiongcun Cu deposit in Tibet was studied as an example to develop a solid mineral resources reserve estimation system by using MATLAB platform based on the Kriging theory. The work includes data analysis ,Variation function analysis ,Kriging estimation ,reserve calculation and geological reliability assessment etc.. the reserve prediction for the Xiongcun Cu deposit in Tibet was carried out to obtain the result data form, and the fitting analyses were undertaken to the primary ore body, the secondary ore body, the oxidized ore body, the total ore body, the ore body natural shape as well as the ore body shape under the industrial controlling grade. After comparison of the results with the estimated reserve data by using professional software MineSight, it is concluded that the system is reliable and practical.
