定向独立权模型及其在矿产资源预测中的应用

ORIENTED ISOLATED WEIGHT MODEL AND ITS APPLICATION TO MINERAL RESOURCES PREDICTION

提出了一种矿产资源靶区定位预测的统计方法———定向独立权法．该方法将统计单元关联度定义为诸地质变量的线性组合，即 Ｙ＝ Ｘｄ ．通过研究地质变量作用于评价目标参考变量（ 例如，矿化强度、矿床和矿点数目或规模等） 的方向和相对大小来确定诸地质变量的权系数ｄ ；用统计单元之间的关联度（ Ｙ）

An oriented isolated weight model, a statistical method for the orientation forecasting of the mineral resources target region, is proposed in this paper. In this model, the correlation between statistical units is defined to be the linear combinations of geological variables used for prediction, i.e., Y=Xd. The effect of the geological variables (such as the mineralization intensity, and the number and scale of the mineral deposits) on the evaluation of the orientations and the relative sizes of the target reference variables can be used for the determination of the weight coefficients (d) of various geological variables. In addition, the correlation (Y) between statistical units may also be applied to the evaluation of the mineral resources target region.
