| 摘 要： | 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(AuAg)异常进行空间信息统计学研究。利用指示克立格法研究g(AuAg)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(AuAg)的空间分布进行估计。根据g(AuAg)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。

| Abstract: | 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. |
