基于GIS技术的西南三江北段矿产资源定量预测与评价

Quantitative prediction and evaluation of mineral resources based on GIS in northern segment of Three River (Sanjiang) Region, Southwest China

在已经建立的中国三江北段地质矿产数据库的基础上,运用加拿大数学地质学家Agterberg提出的证据权重法,并基于MAPGIS技术平台和数理统计分析方法,以及ArcView中的证据权模块,对西南三江北段地区进行矿产资源定量预测与评价,为区域矿产资源的勘测与开发提供科学依据。

On the basis of geological mineral resources database in the northern part of Three River Region, this research has adopted weights of evidence modeling created by F.P. Agterberg to predicate ore_forming anomalies and evaluate mineral resources. The result shows that the application of sophisticated MAPGISARCVIEW and good mathematical model can certainly raise the accuracy and effectiveness of mineral resource quantitative prediction and evaluation.
