空间信息统计学是一门集数学、空间信息科学及计算机技术于一体 ,在时空域内对区域化变量的随机性与结构性进行定量研究的技术。以山东归来庄金矿床为例 ,对其g(Au Ag)异常进行空间信息统计学研究。利用指示克立格法研究g(Au Ag)的空间变异结构特征 ,建立空间结构模型。在对结构模型和估计方案进行交叉验证后 ,对g(Au Ag)的空间分布进行估计。根据g(Au Ag)的空间分布规律 ,探讨其与Au空间分布的关系 ,并对今后该区的找金工作提出建议。
Spatial information statistics is a set of mathematics, spatial information science and computer technology in one, in the space-time domain to quantify the randomness and structural variables of the technology. Taking the Guolaizhuang gold deposit in Shandong Province as an example, the spatial information statistics of g (Au Ag) anomalies was studied. The spatial structure model of g (Au Ag) was studied by using Kriging method. The spatial distribution of g (Au Ag) is estimated after the cross-validation of the structural model and the estimation scheme. According to the spatial distribution of g (Au Ag), the relationship between its distribution and the Au spatial distribution is discussed, and some suggestions for finding gold in this area are put forward.
