摘　　要：克里格法是地质统计学中一种局部估计方法,近年来被广泛应用于固体矿产资源量三维估算工作。本文结合某矿床实例数据,基于对数正态克里格方法开展三维资源量估算研究,并将多种对数正态克里格估算结果与普通克里格法和传统几何方法进行对比分析。研究结果显示:利用本文所述方法可以基于三维地质软件高效开展对数正态克里格方法资源量三维估算工作;本文采用的对数正态克里格方法 1获得的估算结果与原始数据的数据分布曲线更加一致,相关性更强,其估值结果在理论上可能更为可靠。Kriging is a local estimation method in geostatistics,which has been widely used in 3D estimation of solid mineral resources in recent years.In this paper,many lognormal Kriging estimations on a mineral deposit are compared with those of the conventional Kriging method and traditional geometric methods.The results indicate that the lognormal Kriging method 1 as described in this paper can be more efficient in resource estimation based on 3D geological software.This method may be more reliable in theory for its results are much more correlated or more consistent with the distribution curve of the original data.
