摘要:

地学研究普遍面临数据缺失与稀疏分布的问题,空间插值是地学数据分析的核心任务之一。现有基于统计学与几何学的方法在小样本、非平稳空间过程建模方面长期存在缺陷。杨赤中滤波与推估法(简称“杨赤中法”)是一种融合几何与统计思维的空间相关性建模方法,在矿体几何制图等小样本、非平稳空间过程插值应用中具有优势。本文首先完善了杨赤中法解决空间异质环境下空间插值问题仍存在的缺陷,然后重点介绍了杨赤中法近年来的新发展及相对现有方法的优势,最后对未来研究问题进行了展望。杨赤中法可广泛应用于地学现象分布特征分析与演化规律发现。

Abstract:

Geoscience research generally faces the problem of missing data and sparse distribution. Spatial interpolation is one of the primary and core tasks of geoscience data analysis. Statistics- and geometry- based spatial interpolation methods are widely used in spatial data analysis; however, they have long had defects in modeling non-stationary spatial processes. Yang Chizhong filtering and interpolation methods (abbreviated as Yang Chizhong methods) integrate geometric and statistical strategy to quantify spatial autocorrelation structure, which provides a new idea for modeling non-stationary spatial processes. Yang Chizhong methods have unique advantages in modeling small samples and non-stationary spatial processes, such as geometrisation of ore body. In this study, we first overcome two long-standing theoretical shortcomings of Yang Chizhong methods. Then, we focus on the new progress of Yang Chizhong methods in recent years. Finally, we provide an outlook on future research directions. Yang Chizhong methods can widely serve the analysis of distribution characteristics and discovery of evolutionary laws of geo-phenomena.

Key words: spatial statistics, spatial autocorrelation, nonstationary spatial processes, spatial compound variable, Yang Chizhong filtering and interpolation
