摘　　要：笔者在总结赤峰区域成矿规律的基础上,以地质异常致矿理论为指导,利用GIS技术进行赤峰市地、物、化、遥多元找矿信息提取,运用证据权方法对赤峰市进行综合信息金矿成矿预测。在此基础上,采用齐波夫定律对金资源量进行定量估算。结果表明,在赤峰北部有3条北东向有利成矿带,在南部,土城子镇—金厂沟梁镇北西向有利成矿带和老府镇周边地区、喀喇沁旗、八里罕镇周边地区均具有良好的找矿前景。总体资源量约181t,除去已探明储量76t,该区还具有105t金的潜在资源量。The paper summarizes the metallogenic characteristics in Chifeng. Under mineralization caused by geological anomalies, the authors extracted ore search geophysical, geochemical and remote sensing data in Chifeng using the GIS the guidance of the theory of information from geological, technique and carried out metallogenic prediction using the weight of evidence method. On that basis, Qibov＇s law was adopted to estimate the gold resources. The results show that there are three NE-striking favorable metallogenic belts in the north of Chifeng, one NW-striking favorable metallogenic belt in the Tuchengzi Township-Jinchanggouliang Township in the south and three good ore prospect areas at peripheries of Laofu Township, in Harqin Qi and Balihan Township. The total gold resources are～181 tons. When 76 tons of identified is subtracted, there are still 105 tons of potential gold resources in Chifeng.
