目前在地质工作中的成矿预测阶段广泛地应用数理统计的方法.如地质数据的多元统计分析就是应用数理统计方法来研究解决多指标问题的理论和方法.它是根据地质工作的要求,选用合适的数理统计方法来进行整理、分析和综合,最终找出所研究的地质体的数量特征和内在的统计规律性,以便得出较为准确的结论.传统的数理统计方法选择的地质变量的取值都是“清晰的”,而许多地质现象却是不分明的、模糊的.近年来一些地质工作者正在探讨利用模糊数学方法来研究某些地质现象及解决有关方面的地质问题.如模糊聚类分析已经在化探的数据处理工作中得到应用.
At present, the mathematical prediction method is widely applied in the stage of metallogenic prediction in geological work, for example, multivariate statistical analysis of geological data is to apply mathematical statistics to study the theory and method of solving multi-index problems.It is based on the requirements of geological work, Appropriate mathematical statistics to organize, analyze and synthesize, and finally find the number of geological features studied and inherent statistical regularity, in order to come to a more accurate conclusion.Geological variables selected by the traditional mathematical statistics method to take Values are “clear”, and many geological phenomena are unclear and vague.In recent years, some geologists are exploring the use of fuzzy mathematics to study some geological phenomena and to solve the geological problems of related aspects such as fuzzy poly Class analysis has been applied to the data processing of geochemical exploration.
