摘要
对云南省元江中上游 1∶5万土壤测量所圈定的 2 0个地球化学异常进行了模糊综合评判 ,其中甲类异常正确评判率为 10 0 % ,其它几个综合评判值较大的异常经查证均发现了不同规模的矿床 (点 ) ,为研究区异常的筛选和评价提供了一种较为可靠的方法。
Fuzzy synthetic judgement was conducted for 20 geological anomalies delineated by 1∶50 000 soil survey in the middle and upper reaches of the Yuanjiang River, Yunnan Province. The correct evaluation rate is 100% for Rank-A anomalies. Besides, the inspection of some anomalies with relatively high synthetic evaluation values has led to the discovery of ore deposits (occurrences) of different sizes. It is shown that this method provides a relatively reliable technique for the sieving and appraisal of anomalies in the study area.
