摘要
通过对焦家金矿田地球化学异常的分析，并以此为基础设计隶属函数，进而建立了模糊模式。根据隶属函数计算的各个元素信息变量的模糊数，把它作为模糊判别指标，然后用贴近度的度量方法与预测区内待识别的模糊判别指标进行识别。应用此方法对水系沉积物中Ａｕ、Ａｇ、Ｃｕ、Ｐｂ四种元素进行模糊模式识别与处理，并在胶东７８００ｋｍ２范围内进行了金矿预测，其中有些贴近度（Ｔ）异常已经得到验证，获得了较好的效果。
By analyzing the geochemical abnomalities of Jiaojia gold field,and regarding it as the base to design subordinate function,fuzzy model is established.According to the fuzzy figures of each elements′ information variable which are calculated by fuzzy model,and regarding it as fuzzy differentiated index,using the measurement method of “ closing degree (T)”,the awaiting identifying fuzzy differentiated index in the predicating areas can be distinguished.The figures of Ag,Au,Cu and Pb which are from stream sediments were distinguished and processed,and predication of gold mineralization within the scope of 7800km 2 in Jiaodong (east of Shandong) has been done and some “closing degree (T) ”abnomalities proved.
