摘要
在应用地质统计学进行矿床建模工作中,变异函数的计算和拟合占有非常重要的地位,其结果的好坏将直接影响建模效果.针对传统变异函数计算及拟合方法的缺陷,运用稳健统计学理论,讨论了三维情况下实验变异函数的计算以及拟合方法.矿床建模实践表明,采取上述技术取得了良好的效果.
The calculating and fitting of variogram function play a very important role in the work of deposit modeling by means of geostatistic methods, whose results will affect the effect of modeling directly. To get over the drawback of the traditional experimental variogram function calculating and fitting methods, based on the theory of robust statistics, this paper presents a calculation method of three demensional variogram function. The practice of modeling shows a good result.
