摘　　要：为了提供茶园管理的理论依据,对江西省浮梁县10个重点茶乡的30个茶园进行了土样采集与测定,并应用SPSS统计软件进行了主成份分析与聚类分析。结果表明:(1)土壤养分状况存在广泛变异,各因子变异系数为13.17%—63.58%;(2)土壤酸化严重,全氮水平尚好,碱解N含量高,有效铁和有效锰含量较丰富,有效P、有效镁和有效硫含量偏低;(3)土壤可划分为4个不同的等级类型。In order to provide a theoretical basis for the tea garden management,the soils from 30 tea gar-dens in 10 key tea-producing townships of Fuliang County were sampled and determined,and then the principal component analysis and cluster analysis were made by the statistical software SPSS.The results showed that（1） the soil nutrient contents varied widely and the variation coefficients of various nutrients were 13.17%—63.58%;（2）The soil acidification was heavy,the total nitrogen level was good,the alkali-hydrolyzable N content was high,the available Fe and available Mn were rich,but the available P,available Mg and available S contents were somewhat low;（3）The tea garden soils could be divided into four soil types at different levels.
