摘要
应用GIS进行金矿资源评价是一项较为复杂的系统工程。建设好地学空间数据库是资源评价的基础 ,正确建立资源评价模型和确定地质变量是资源评价的技术核心。依据区内成矿地质条件和矿化特征 ,采用“WMR”
The GIS based appraisal of gold resources is a complex systems engineering.Setting up geospatial data bank is the basis on which resources are appraised.Proper modeling for appraisal of resources and determination of geological variables are the technical core of the work.This paper makes use of “weights of evidence method”,“multiple information statistic regression method”and“regional metallogenic law”for appraisal in terms of metallogenic geological conditions and mineralization features of the area studied.The result has been proved successful.
