摘　　要：介绍了证据权重法及其理论基础,根据层间氧化带型砂岩铀矿成矿理论,应用由ArcView3.2二次开发形成的砂岩铀矿勘查信息系统软件在克鲁伦盆地内提取控矿信息,最后通过证据权重分析综合证据因子,完成盆地内层间氧化带型砂岩铀矿的远景预测。This paper describes the evidence weighting method and its theoretical basis. Based on the metallogenic theory of interlayer oxidation zone sandstone uranium deposits and applying information system software for exploration of sandstone uranium deposits which was formed by secondary development of ArcView3.2, the authors extracted orecontrolling information from Klulun basin, analyzed integrated evidence factors through evidence weight, and finally completed prospective prognosis of the interlayer oxidation zone within the basin.
