信息不对称条件下的成矿信息集成方法

针对目前成矿信息不对称等的问题,提出组合作用域信息集成方法,并以桂西—滇东南地区锰矿为例,利用线性回归分析进行了资源量预测。通过成矿信息场分析方法,提取某些地质类的成矿信息,并建立了桂西—滇东南地区锰矿成矿预测指标集,同时考虑到模型区和预测区的找矿信息不对称问题,采用组合作用域集成线性回归分析,建立研究区锰矿资源量预测模型。实例分析表明,采用组合作用域信息集成预测模型能精细、有效地对研究区中的锰矿资源量进行预测,其预测结果对进一步找矿具有很好的指导意义,利用组合作用域信息集成方法可帮助解决成矿信息不对称的问题。

Integration method for metallogenic information under condition of metallogenic information asymmetry

Focusing on the issue of metallogenic information asymmetry,a new method of metallogenic information integration based on combination domains was proposed,and an instance study of manganese resources prediction using the linear regression analysis was made by taking the Western Guangxi—Southeastern Yunnan areas as an example.Through the field analysis method of metallogenic information,some kinds of geological metallogenic informations were extracted,and the index set of metallogenic prognosis in the West Guangxi—Southeast Yunnan was built.Considering the issue of metallogenic information asymmetry between the model area and the prediction area,the prediction model of manganese resource was built using the linear regression analysis based on the integration of combination domains.The instance study indicates that the linear regression model based on integration of combination domains can be used to predict the manganese resource more precisely and effectively,which can resolve some issues of metallogenic information asymmetry,and the prediction results have indicative significance to the further predicting.
