专家克里金插值法在空间插值中的应用

摘要

克里金插值是一种进行局部估值的方法,但它并不能对局部的地质特征进行智能分析.因此,在很多时候其插值结果不能体现数据的一种局部异构特征.针对这一问题,提出了一种专家克里金插值法,这种方法是在普通克里金插值法的基础上加入专家地质知识,使得插值结果更能符合实际的地质情况.对该方法的原理、模型进行了详细的论述,并通过实例验证该方法的有效性.%Kriging algorithm is a method for estimating geological features in a certain area. However, this kind of estimation is not an intelligent one. Thus, the result cannot show the heterogeneous characteristics of the estimated area. To solve the problem, the authors put forward the Expert Kriging Interpolation Method, which applies experts' geological knowledge in kriging interpolation, so that the result meets actual geological conditions. The theories and models of the Expert Kriging are described in detail. The effectiveness of such method is verified by case study.
