| 摘 要： | 非线性现象普遍存在于许多自然科学的研究之中,线性地质统计仅限于有效数据的线性组合;而某些非线性方法不容易处理,如条件期望的前提条件苛刻,计算复杂耗费大;析取克立格法(DK)介于两者中,利用二元概率分布函数进行估计,更有效、准确且易实现。并能很好地估计Z(x)的任意函数,解决可回采储量估计等现实问题。介绍了DK方法的基本理论和方法及其应用,并给出了计算实例。

| Abstract: | Many problems in nature science is non-linear that cant be solved using linear geostatistics techniques which just use linear combinations of available data. Even some non-linear methods are not satisfying, Condition Expectation(CE),for example, can only be determined for a rigour condition. Disjunctive Kriging (DK) is in the middle of the two, which uses bivariate probability distribution function. It's more perfect and easier to be applied, which is also perfect for any function of Z(x) to solve problems in reality like estimate of recoverable reserve. This paper studies basic theory and methods of DK with data examples. |
