摘　　要：阐述了基于SIG的证据权法矿产资源评价体系结构和方法,并以西南三江成矿带为示范区进行了铜矿资源预测评价。示范区分别设置一个主结点和三个省级结点,并在结点服务器上进行了相应的数据与服务的部署。评价结果表明,基于SIG的矿产资源评价很好地解决了空间信息资源共享与应用问题,提高了评价效率,是一种有实用价值的评价新方法。The framework and the method of evaluation on mineral resources by weight of evidence based on SIG are introduced in detail. Meanwhile, its application on the evaluation of copper mineral resources in the Three-river Metallogenic Belt, Southwest China is discussed as an example. The node is deployed on server in Beijing and three sub-nodes are deployed on the server in each province. Geological database and services are deployed on each server. It proves that the method on mineral resources based on SIG is a new effective one, which not only solves the problem in sharing data, but also improves efficiency of evaluation.
