基于GIS的大兴安岭矿产预测信息提取研究

Research on extraction of forecast information for mineral in Daxinganling District based on GIS

分析地质、物探及遥感成矿预测原理,提出地质、重力、遥感控矿标志表达模型。在基于GIS原理与方法的基础上,系统地论述多源矿产预测信息的提取方法,实现地质、重力、遥感自动化信息提取。以内蒙东部中大比例尺矿产预测项目为例,运用文中提出的矿产预测信息提取方法,取得预期效果。

Analyzing metallogenic prediction theory based on geological,geophysical exploration and remote sensing（RS）,the paper presents metallogenic prediction expression model.Based on GIS principle,the paper presents a method that transforms spatial information including geology,geophysics and RS into geological variables in order to establish variable tables automatically.During the project of middle-large scale metallogenic prediction in the east of Inner Mongolia,we have achieved the satisfactory effect by employing the method presented.
