山东归来庄金矿区g(Au/Ag)的空间信息统计学特征

STATISTICAL FEATURES OF SPATIAL INFORMATION TO g(Au/Ag)-ANOMALY IN GUILAIZHUANG GOLD ORE AREA, SHANDONG PROVINCE

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。

Statistics of spatial information is a science which incorporates mathematics, the science of spatial information and computer technology, and it is a technology which can study quantitatively the regional variables having randomicity and structural characters at temporal—spatial domain. As an example, this paper did some statistics of spatial information research on g (Au/Ag) in the Guilaizhuang gold ore area, Shandong Province. By studying the characters of spatial distributing variability regularity of g (Au/Ag) with indicator Kriging, its spatial structure model was constructed. After cross—validating the parameters of the structure model and the estimating project, the spatial distribution of g (Au/Ag) was modeled. Based on the statistics of spatial information research, the relationship between the distribution of g (Au/Ag) and Au was discussed and some suggestions for the future work on this area have been proposed.
