摘　　要：在矿床模型综合地质信息预测方法中,区域矿产评价模型包括远景区圈定要素组合、远景区优选要素组合、矿床数估计要素组合和资源量估算要素组合,它们成功地解决了矿产预测中的信息不对称以及知识驱动和数据驱动相结合的问题。通过对赤峰燕山期红花沟式岩浆热液型金矿资源的定位、定量预测,共圈定远景区11个,其中A类远景区4个,B类远景区3个,C类远景区4个;预测潜在矿床数8个,潜在资源量306.532 t。本区该类型金矿资源潜力巨大,具有很好的找矿远景。Model of regional mineral resource potential assessment includes factor associations of delineating tracts, optimally selecting tracts, estimating numbers of deposits and resources in methodology of mineral resource potential assessment for deposit models using integrated geological information. It successfully solves the problems of information asymmetry and combination of knowledge and data. Based on the position and quantification prediction of the Yanshanian magma-thermal gold deposit in Chifeng, 11 tracts have been delineated which include 4 A-grade tracts, 3 B-grade tracts and 4 C-grade tracts, and the 8 potential deposits and 306. 532 tones resources have been predicted. Results of gold mineral resource potential assessment are good and indicate that potential of gold resources is very large and deserves to do the further exploration.
