摘要
分析区域化变量的特征,采用合理的插值方法是观察靶区样品分布及估计靶区样品储量的重要手段。该文在分析趋势模型和线性估计无偏条件的基础上,讨论了漂移向量对求解泛协克里格方程组的影响,描述了区域化向量的估计过程。以某矿区样本为例提出该矿区的泛协克里格法可视化计算流程,不但完成了对矿体的内部属性建模,并且较准确地计算了矿体储量,误差为100KG左右。实验证明,泛协克里格法可为研究矿体的空间分布提供科学依据。
Based on the analysis of regionalized variable characteristics,adopting rational interpolation method has become one im-portant means for observe the target sample distribution and estimation of the target zone.During analysis of trend model and linearestimate unbiased condition, discusses some drift factors that influence the effects for solving Universal Cokriging equations, de-scribes the process of estimating regional vector. This paper puts forward the visualization computing process of the UniversalCokriging on some mining area. Not only finished on the internal attribute modeling, and accurately calculate the ore reserves, theerror is about 100 KG. The experiment proved, the Universal Cokriging provide a scientific basis for the study of the spatial distribu-tion of ore bodies.
