摘　　要：在分析了个旧地区锡多金属成矿地质特征的基础上,提取了与成矿相关的地层、构造、物探、化探、遥感异常等8个证据图层,建立了证据权模型并根据后验概率圈定了4个成矿远景区,为该地区进一步找矿提供参考。The text based on the analysis of metallogenetic geology characteristics of the tin-polymetallic deposit in Gejiu district,8 prediction variables which relate with mineral formation are chosen,these variables containing stratum,structure,geophysical,geochemical,remote sensing.Then built the evidence weight model and outline four prospect targets according to calculating posterior probability,supply suggestion for further ore-finding of this area.
