克里格法（Kriging）是地统计学的主要内容之一，从统计意义上说，是从变量相关性和变异性出发，在有限区域内对区域化变量的取值进行无偏、最优估计的一种方法；从插值角度讲是对空间分布的数据求线性最优、无偏内插估计一种方法。-Kriging (Kriging) is one of the main geostatistics, statistically speaking, is　the variable correlation and variability within a limited area of the value of regionalized variables unbiased, best a method for estimation　speaking　the perspective of a data interpolation spatial distribution of solving linear optimal, unbiased estimate of the interpolation method.
