摘　　要："有利因素相关"法多应用于矿产资源量定量预测中,在成矿远景区定位预测中尚未见及。文章在研究云南哀牢山成矿带南段地质特征、总结该区金矿成矿规律和综合信息找矿模型的基础上,首次尝试以"有利因素相关"法有利度作为预测远景区圈定指标,对本区金矿进行了成矿预测,共圈定有利找矿远景区4处:A类找矿远景区2处。全区已知20个金矿床(点),其中85%落于A类远景区内,10%落于B类远景区,5%落于A、B类远景区附近,与实际吻合较好。预测结果表明,以"有利因素相关"法有利度作为预测全景区圈定指标进行矿产资源成矿预测是可行、有效的。＂Favorable factor correlation method＂ is almost applied for mineral resource reserve forecasting, and never found in mineral resource perspective districts targeting. Based on geological features, mineralization pattem and model of gold deposits, comprehensive information of relevant gold deposits, using favorable value as parameter of ＂favorable factor correlation method＂ perspective districts are targeted, among which two are type A and four are type B by first attempt for targeting perspective districts is analyzed. Six gold Of all twenty gold deposits discovered, 85% is in A type perspective districts, 10% is in B type perspective districts, and 5% is close to A or B type perspective districts. Predicted targets are coincident with existing gold deposits, which demonstrate that the ＂favorable factor correlation method＂ is reliable and effective for mineral resource targeting.
