灰色GM(1,1)模型应用于金矿床定量预测研究及其效果评析
APPLICATION OF GREY MODEL GM(1,1) TO QUANTITATIVE METALLOGENIC PROGNOSIS OF GOLD DEPOSITS AND ITS RESULT APPRAISAL
【摘要】 介绍了灰色 GM(1,1)模型基本原理及建模程序 ,列举了该模型应用于金矿床深部定量成矿预测研究的 3个具体实例 ,通过对预测结果的综合对比分析 ,认为矿体自身变化程度及模型本身单调性函数特征是影响预测精度的主要因素 ,提出了矿体变化程度及规律研究是有效应用 GM(1,1)模型进行成功预测的前提和基础 .
【Abstract】 By a brief introduction to the fundamental principle and construction procedure of Grey Model GM(1,1) ,three examples are listed about applying this model to deep level quantitative metallogenic prognosis of gold deposits After a comprehensive comparison and analysis of the prospecting results,it is concluded that the variation degree of ore body itself,and monotonous function feature of the model are main factors that influence the prognostic precision The study on the variation degree and regularity of ore body is the premise and base for effective prognosis with GM(1,1) model
