中文摘要：

介绍了地质统计学原理、变差函数模型及格立克法的计算公式。运用地质统计学方法，以变差函数为工具，根据勘探钻孔数据，对岩层标高的变化进行了模拟。三维立体图直观显示了岩层变化的空间分布特征，为矿产开发的可靠性提供岩层空间变化形态分析直观依据。

英文摘要：

In this paper, the principle of geostatistcs, the model of variogram and the method of kringing are introduced. The variability of the terrane elevation is simulated according to the geostatistcs, variogram and the drilling data. The three-dimensional figure shows the spatial distribution characteristics of the terrane variability, which will provide the intuitive support of the spatial distribution characteristics of the terrane variability and make the mining exploitation more reliable.
