摘　　要：本文以特征分析中的逻辑矢量长所建立的模糊关系矩阵,作为不同地质变量对不同等级评语(矿床规模或矿石品位贫富)的权系数.因此,作为一种变换,模糊关系矩阵可以使问题从地质变量空间向评语空间转换,从而解决勘探基地的评价问题.本文简述模糊综合评判的基本原理,重点以实际例子介绍方法的应用,并以Zadeh算子与Ha-macher算子分别计算评语的隶属度.计算结果表明Zadeh算子没有Hamacher算子(r=0.1~0.12)精确.12个己知矿床用Hamacher算子回判的结果正确判别率100%.文后附有BASIC语言编制的计算程序供应用.Based on the logical vector from characteristic analysis, this paper constructs a fuzzy relation matrix, a weight of geological variables for different grades of comment ( scale of deposit or grade of ore) . Thus, as a transforming, the fuzzy relation matrix transforms a problem from the space geological variables to the space comments. It solves the problem of exploration priority excellently. The paper introduces the principle of fuzzy synthetical comment and illustrates its application with a few examples. The paper calculates the subordinates of comment with zadeh and Hamacher operators separately. The results prove that the application of Hamacher operator is more accurate than Zadeh operator ( while r=0.1-0.12). The return discrimination of 12 known deposits by Hamacher operator is 100% correct. A calculation program written in BASIC is given towards the end of the paper.
