摘要
讨论了时空信息统计学 (地质统计学 )的若干基本理论和方法 :1)若干基本概念 ,包括时空域的随机变量和随机函数 ,仅考虑空间域或时间域的不足 ,空间域与时间域之间的差异 ,二阶平稳假设及内蕴假设 ;2 )时空域信息的平稳线性最优估计 ,主要讨论了变异函数与协方差函数及平稳线性最优估计方法 ;3)时空域信息的线性非平稳最优估计 ,提出了漂移和涨落的概念 。
Some of the problems about basic theory and methods of spatio temporal information statistics (geostatistics) are discussed. It includs: 1)Some basic concepts about spatio temporal information statistics (geostatistics), including spatio temporal random variance and random function, the shortage of the way considering only spatio domain or temporal domain, the difference between spatio domain and temporal domain, second order stationary hypothesis and the intrinsic hypothesis; 2)Linear stationary optimal estimation of spatio temporal information, including variogram and covariance, and linear stationary optimal estimation; 3) Linear nonstationary optimal estimation of spatio temporal information, including the concepts of excursion and fluctuation, the form of excursion and linear nonstationary optimal estimation.
