| [摘要]因综合信息成矿预测涉及的控矿因子较多,各度量指标间具有一定的层次性,有些定性
指标还具有模糊性特征,高精度和定量化一直是制约其发展的难题。为了实现对研究程度较低的新矿
区的成矿预测,并解决上述难题,本文试图将专家的主观判断与精确的数学运算巧妙地融合,将复杂问
题及定性指标定量化,使评价过程和评判结果更具客观性,建立一种层次分析-多级模糊评价的成矿预
测模型。以贵州大厂锑(金)矿田普晴矿区为例,选取地质、化探和遥感多元致矿信息,基于GIS 平台,建
立了层次分析-多级模糊评判的综合信息成矿预测模型,最终圈定出锑(金) 矿远景区18 个,其中玉、域
和III 级远景区分别有4 个、5 个和9 个。根据勘查验证,预测结果较为客观有效。 |

| Abstract:The metallogenic prediction based on comprehensive information involves many factors which have the features of hierarchy,and some qual鄄
itative factors have fuzzy features. So the high precision and quantification are always difficult problems restricting its development. In order to realize the
metallogenic prediction in new mine fields which have been studied to a low degree,and resolve the above mentioned difficulties,this work tries to build the
AHP model and multiple-grade fuzzy evaluation model for metallogenic prediction. These models are the synthetic model which combines the expert爷s sub鄄
jective ideas with exact math calculation,making complicated problems and qualitative factors quantified,and the evaluation process and results more ex鄄
act. Taking the Puqing Antimony-gold mine area of Dachang ore field in GuiZhou province for example,and geology,this work uses data of geology,geo鄄
chemical exploration and remote sensing to make prediction on the platform of GIS,the AHP moldel and multiple-grade fuzzy evaluation model. Finally,18
prospecting areas of antimony-gold are determined,including four I grade,five 域grade antimony and and nine 芋grade areas. The exploration examination
shows that this prediction method is fairly effective and can achieve rather accurate forecasting results. |
