摘　　要："相似类比"、"异常致矿"等成矿预测理论的指导下,采用层次分析的方法,通过综合预测模型的建立、量化和模糊逻辑的运算,完成了沂南金矿两泉庄工作区预测靶区的圈定及解释,工程验证效果良好。实践证明,基于GIS的综合信息预测,大大提高了成矿信息提取和综合分析的效率,为危机矿山"摸边探底"提供了有效的方法和手段,促进了矿山的可持续发展。In the 21st century, with the fast development of industry, there is much need for the mineral resources; however, a few mines face serious resource crisis. Looking for ore in the outside and in the depth of the mine is a basic and main way that solves the crisis mine problems. Additionally, with the development of geosciences and the continuing progress of mineral exploration, mass geoscience data have been accumulated, and the mineral exploration has entered a new era that is marked by the heavy dependence of ore finding on comprehensive information. In this article, under the guidance of metallogenic forecasting theories such as the Analogy Comparison and the Anomaly-caused Mineralization, the authors utilized GIS technology, applied analytic hierarchy process （AHP） method, through building, quantifying and operating in fuzzy logic on the prospecting model of synthetic information, acquired and interpreted the target area in the Yi＇nan gold mine, and discussed the method and process in multi-information metallogenic prediction based on GIS. The engineering testing and verification results indicated that the prognostication from comprehensive information based on GIS greatly improved the efficiency of metallogenic information extraction and integration. This method provides a kind of effective method and means for the prognostication for periphery and deep sites of resources crisis mine, and also promotes sustainable development of mine.
