本文运用数量化理论Ⅰ、Ⅱ两个数学模型,对河南铝土矿资源潜力进行了评价。数量化理论不仅能处理定性地质数据,而且也能处理兼有定性和定量的双重型数据。数量化理论Ⅰ不仅可以用来,对未知区进行资源潜力评价,而且也可筛选重要地质变量。数量化理论Ⅱ通常只能对成矿远景区进行预测,确定不同级别远景区的空间位置。本文研究将数量化理论Ⅱ与回归分析结合起来,所得到的判别得分作自变量,各单元对数值作因变量,取得了资源总量预测的较好效果。
In this paper, two mathematical models of quantitative theory Ⅰ and Ⅱ are used to evaluate the resource potential of bauxite in Henan Province. Quantitative theory can not only process qualitative geological data, but also deal with double type data, both qualitative and quantitative. Quantitative theory I can not only be used to evaluate the potential of unknown regions, but also to screen important geological variables. Quantitative Theory II usually can only predict the mineralization prospects and determine the spatial location of the different levels of the prospects. This paper combines quantitative theory II with regression analysis. The discriminant scores obtained are used as independent variables and the numerical values of each unit are used as dependent variables, and a good result of total resource forecasting is obtained.
