摘　　要：Torgerson方法是一种多维标度法。用于研究变量或样本对象 ,它从一组对象的两两之间的相似性度量或非相似性度量出发 ,求出这组对象在某低维空间中的标度 ,从而发现这组对象的整体关系。通过它在某斑岩铜钼矿的蚀变与矿化分析的实例应用 ,说明该方法在矿产资源评价方面具有一定的实效性。Torgerson method is a kind of multidimensional scaling method. It is applied to study the objects of variable or sample. Firstly, it begins with the data of similarity measure or non-similarity measure between the objects of a group ones. Then, we work out the scales of the group objects in a low dimensionspace. Finally, we will find the globle relation of the group objects. According to the application of the method to the alteration and mineralization analysis of a porphyry copper-molybdenum deposit, Torgerson method proves to be really effective in the evaluation of mineral resources.
