摘要
地质统计学中常用的插值方法有:距离幂次反比法、普通克里格法、多重指示克里格法等。本文分析了它们各自的优缺点,并在此基础上提出了一种新的插值方法:指示距离幂次反比法,相比其它几种方法具有插值速度快、计算结果精度高、不受特异值的影响、易于实现三维可视化的优点。本文在最后给出了这一方法的具体应用,测试结果说明,指示距离幂次反比法在一定的领域内确实可用,并具有其它方法难以具备的优点。
The usual interpolation methods used in geostatistics are as follows: the method of inverse distance weighted, ordinary kriging method, muliplyindicator kriging and so on. This paper analyses the merits and shortcomings of these methods and invent a new way based on all the methods, that is indicator inverse distance weighted method. Compared with other interpolation methods, the new method can run quickly with accuracy,avoid the influence of the special value and easy to visualize the results in 3D environment. At the end of the article, an example of the application on the new method is given and test the method carefully. As a result of the experiment, indicator inverse distance weighted method is useful in some fields and has the merits that other methods don't have.
