混合模糊证据权模型在河北承德煤炭资源预测中的应用

应用模糊逻辑法、加权证据权法相结合的混合模糊证据权模型和GeoDASGIS技术开展了承德煤炭资源预测研究。采用模糊逻辑法对与煤炭矿床有关的证据层进行了系统的处理和分析,并在此基础上采用加权证据权方法编制了成矿后验概率图,最终划分出5个主要的找矿远景区。研究结果不仅对进一步开展预测区优选评价具有重要的参考意义,而且为混合知识驱动与数据驱动的混合预测模型提供了一种可借鉴的有效方法。

Application of hybrid fuzzy weights of evidence model in mineral resource assessment for coal in Chengde area, Hebei, China

The hybrid fuzzy weights of evidence model method and GeoDAS GIS were applied to delineate targets for exploration of coal mineral deposits in Chengde region, China. Based on the comprehensive analysis of relative evidential layers of coal deposits using fuzzy logic method, the five targeting areas were delineated using fuzzy weights of evidence method and were suggested for further exploration. The result not only can be a great referenced value for mineral resources prediction and evaluation but also provides an effective way to combine the knowledge-driven model with data-driven model.
