摘　　要：对贵州地区33个乡镇茶园土壤中铅、镉、铬、铜、汞、砷、硒7种元素含量进行了检测。运用SPSS 12.0软件对所掌握的数据进行聚类分析。结果表明,33个茶园土壤共分为5组,共有26个茶园土壤被划入第1组。对聚类分析的分组结果进行单因素方差分析,判断各组间7种元素的含量特征是,铅、铬、铜、砷4种元素含量组间差异极显著(P<0.01),硒元素含量组间差异接近显著水平(P=0.058)。说明,该聚类分析结果是有效的,可为贵州省茶园规划及相关产业政策的制定提供依据。The Pb, Cd, Cr, Cu, Hg, As and Se content of tea plantations soil samples from 33 villages and towns in Guizhou was determinated and the tested data was analyzed by the SPSS 12.0 software for cluster analysis. The results show that the soil of 33 villages and towns are divided into 5 groups, of which, the soil of 26 villages and towns is belong to group I . There is very significant difference between different groups in Pb, Cr, Cu and As content （p〈0. 01） and is close to significant difference between different groups in Se content（p= 0. 058）, which indicates that the results from the cluster analysis is effective and can provide the useful information for making the plan of tea plantation and relative industry police in Guizhou .
