由于黑龙江省西北部地区地质勘探程度低,而且研究区已知矿床(点)数目少,利用统计方法的证据权重法不能应用于该地区。为此,将黑龙江省西北部地区的基础地质、区域成矿规律、金矿床成矿特征等方面取得的认识建立了一个“专家知识库”,并与“证据权重法”结合起来,建立一个基于专家证据权重法的矿产资源定量评价系统。利用该系统对黑龙江省西北部金矿进行预测并取得了很好的效果,为在黑龙江省西北部进一步找矿奠定了基础。

As a result of the low level of geological prospecting and the few sites of known mineral deposits in the northwest of Heilongjiang province, weight evidence method which is based on statistics is not suitable for this area. Therefore, Whith combined weight evidence method with an “expert knowledge system” which is built on the basis of knowledge achieved in basic geology, regular of regional mineralization and characteristics of gold mineralization, we establish a mineral resources quantitative evaluation system of mineral resouces based on expert weight evidence method. Applying this system to evaluate gold mineral in the northwest of Heilongjiang achieves good results and lays a foundation to further look for minerals in this area.
