地质统计学是以变异函数和变异曲线为基本工具研究区域化变量的空间相关关系.由有用样品数据计算得到的实验变异曲线,往往需经数学方法与实际经验拟合一条反映区域化变量空间相关和变化特征的圆滑变异曲线,从而获得一个理论数学模型,以供估算储量、研究矿体地质特征、取样最优化等方面利用.根据实验变异曲线的特点差异,选用的理论数学模型有球状模型、代·威依斯模型、线性模型、ahλ模型、指数模型、空穴效应模型和随机模型等.但至今用得最多的
Geostatistics is based on the variation function and the variation curve as the basic tool to study the spatial correlation of the regionalized variables.Experimental variation curves calculated from the useful sample data often need to be fitted by mathematical methods and practical experience to reflect the spatial correlation of the regionalized variables And the variation characteristics of the smooth variation curve to obtain a theoretical mathematical model for the estimation of reserves to study the geological characteristics of the ore, sampling optimization and other aspects.According to the characteristics of the experimental variation curve differences, the selection of the theoretical model of a spherical model, Generation Weisi model, linear model, ahλ model, exponential model, cavitation effect model and stochastic model, etc. However, the most used
