限制性克立格法在地学中的研究与应用

Research and application on the method of restricted kriging in geology

普通克立格法在矿产资源储量计算中通常会产生较多的平滑效应,本文运用限制性克立格法,通过其限制性条件来解决这一问题.阐述了限制性克里格的理论方法,设计出限制性克立格法的计算过程,结合实例,通过块段模型的结果对普通克里格法与限制性克里格法进行比较,结果表明,限制性克立格法在抑制平滑效应方面能够取得较为理想的结果.

Ordinary Kriging often produces some smooth effect in the reserve estimation, the article proposes Restricted Kriging to solve this problem. Discussed the thesis of Restricted Kriging, designed the calculating procedures of Restricted Kriging, combined the example, compared the results of Ordinary Kriging and Restricted Kriging by block modeling, shows that Restricted Kriging can get better prediction in retaining smooth effect.
