摘要
首先讨论特征分析模型的几个问题，由此以地质异常理论为基础，应用定性数据定量分析方法，构造变量选择方法及变量权值计算方法，并应用改进的决策分析模型对某金矿床定量矿物找矿模型进行了研究，取得了较好的地质效果。
In this paper, some problems of temary code of quantitative data are discussed in detail. It is suggested that the binary code data should be used in stead of temary data in characteristic analysis. On the basis of this study, some improvements in the characteristic model are studied. We thind that there may be some weight for the absence of the variables. At last, the application of the improved model for quantitative prediction of the gold deposit is given.
