克立格估计邻域大小的确定方法

分析了以往地质统计学确定估计领域域时的不足，提出了克立格估计方差、均值权，真值与估计值之间线性表达式的斜率、真值与估计值的相关系数以及克立格估值中的负权样品数等可作为确定克立格估计领域域大小的关键参数，对于脉状脉体而言，除了考虑以上参数外，还应限制矿体厚度方向上的大小。

THE METHOD OF DETERMINING DIMENSION OF ESTIMATED NEIGHBOURHOOD IN KRIGING

On the basis of analysising the difficiency of determination method of Kringing estimated neighbourhood in geostatistical study in the past, the paper proposed that estimation variance, weight of mean, slope of the expression between true value and estimated value,coefficient between true value and estimated value and number of samples with nagtive weight in SK can be the parameters to determine the size of Kriging estimated neighbourhood. In the mean time, the paper also emphasized that the dimension of the neighbourhood in the direction of being vertical to the vein in vein type deposit.
