摘　　要：通过对云南拉巴—东炉房地区开展1∶5万土壤地球化学测量工作,总结了该区土壤地球化学找矿研究.以数学地质统计方法为指导思想,对所采样品数据,利用SPSS软件进行R型聚类分析,采用最短(邻近)分类准则(nearest neighbor)及皮尔森相关系数,生成聚类分析谱系图,以研究各元素间的共生组合关系,及空间分布规律,并在此基础上圈定出优选靶区,为该地区的找矿工作的开展提供一定的理论依据和技术支持.Through the 1∶50 000 soil geochemical survey of Laba-Donglufang area in Shangri-La,Yunnan,we summarized the research of soil geochemical prospecting in this area. Taking mathematical geology statistical method as the guiding ideology,the R cluster analysis of the sample data was carried out by using the SPSS,and the shortest（near） classification criteria（nearest neighbor） and Pearson correlation coefficient were used to generate the pedigree chart of cluster analysis,so as to study the association and spatial distribution among elements. And on this basis,delineating the optimization target area might provide a theoretical basis and technology support for the regional prospecting work.
