摘要
Field theory is introduced to express the metallogenic influence of linear geologic bodies and overcome limitations of traditional buffer method in evidences construction, objectiveness of evidence factor designation and information loss due to binarization of evidence.Linear regression analysis method is proposed to filter the evidence factors. On basis of analyzing metallogenic conditions of quality manganese ore in southwestern Guangxi and GIS spatial analysis 15 evidence factors are predicted.
