| 摘 要： | 根据研究区铜矿的成矿规律，在已经建立的三江地质矿产数据库的基础上，将三江地区划分为6418个统计单元，利用GIS的空间分析功能提取了地层、岩体、断裂在内的12个证据图层，建立了证据权找矿模型，圈定出44个找矿远景区，其中A类远景区9个，B类远景区15个，C类远景区20个，并预测了找矿潜力。

| Abstract: | On the basis of the databases of geology and copper ore deposits, 6418 statistical units are divided for the Jinshajiang-Lancangjiang-Nujiang area in southwestern China. The authors have extracted 12 evidence factors including strata, rock masses, faults and so on with the aid of GIS spatial analysis, and constructed the evidence weight prospecting model. 44 forecast prospects are delineated, of which 9 are grouped into A type, 15 into B type and 20 into C type. |
