对确定铅锌矿床勘探类型数学方法的探讨

A Mathematical Method for Ascertaining the Prospecting Type of Pb-Zn Deposits

以我国铅锌矿床勘探类型为例,提出一种用多层次加权评分评价与模糊识别相结合的定量数学方法.结果表明,该法较好地弥补了以定性为主的传统方法的缺陷,具有简便实用、结论明确、定量化程度高等特点.

Based upon the prospecting types of Pb-Zn Deposits in China, the author suggestes a quantifiedmathematical method by combining the multilevel weighted factor score evaluation method and thefuzzy recognition method for ascertaining the prospecting type of these deposits. It has been demon-serated by practical results that the method devised by the author may overcome fairly the shortcomings of those conventional, chiefly qualitative, methods and is characterized by its merits: simpleand applicable, definite in conclusion and higher in quantification.
