摘　　要：为探讨自然保护区森林生态系统植物铝含量状况,以雷公山自然保护区合轴荚蒾(Viburnum sympodiale Graebn.)等5种常见植物为研究对象,对其叶片Al含量进行了测定分析。结果表明:研究区常见植物叶片Al含量在129.65~775.80mg·kg^(-1)之间变化,平均值为380.53mg·kg-1,超出了已报道的陆生维管植物中木本被子植物Al元素平均含量范围的最大值,植物存在受铝毒的潜在风险。该区植物叶片Al含量相对稳定,呈正偏态分布,在5种植物中,仅合轴荚蒾与湖南悬钩子(Rubus hunanensis Hand-Mazz.)等其他4种植物间差异显著(P<0.05)。To investigate the characteristics of Al contents in forest plants in nature reserve,The concentrations of Al in the leaves of five common plants in Leigong Mountain(Viburnum sympodiale Graebn.,Rubus hunanensis Hand.-Mazz.,Rhododendron decorum Franch.,Euonymus nitidus Benth.and Litsea pungens Hemsl.)were measured.The results showed that the contents of Al varied between 129.65 and 775.80 mg·kg-1 with the average of 380.53 mg·kg-1,which were higher than previously reported average level of the terrestrial woody angiosperms.Therefore it was known that plants in Leigong Mountain were under threat of Al poisoning.The contents of Al in plant leaves were relatively stable and showed positive skew distribution.The concentrations of Al in the leaves of Viburnum sympodiale Graebn.were significantly different(P<0.05)from the concentrations of Al in the leaves of the other four plants(Rubus hunanensis Hand.-Mazz.,Rhododendron decorum Franch.,Euonymus nitidus Benth.and Litsea pungens Hemsl.).
