摘　　要：通过对龙固井田研究区8个钻孔资料的分析,构造了新近系岩性组合特征系统聚类分析模型,分述了构建模型的几个重要步骤,并将欧式距离、标准欧式距离、马氏距离和明科夫斯基距离4种距离计算方法获得的聚类谱系图进行比较分析,发现在对于井田岩性组合特征聚类分析方面,欧式距离聚类分析更为符合矿井的实际情况。The data of eight boreholes located in the research area of Longgu minefield was systematically analyzed, and the model of hierarchical cluster analysis for the lithologic assemblage characteristics from Neogene was established and several important steps which constructed the model were stated respectively. In the meanwhile, it analyzed and compared the clustering pedigree chart by using four calculating method of distance including the Euclidean distance, standard Euclidean distance, Mahalanobis distance and Minkowski distance, and found that the clustering analysis based on Euclidean distance can correspond with the actual situation of the mine.
