摘　　要：甜槠林是古田山自然保护区常绿阔叶林主要类型之一。通过对甜槠群落特征进行分析和研究 ,结果表明 :甜槠群落中 ,甜槠的优势明显 ,呈单优势群落。群落外貌以小型和中型叶、单叶、非全缘、革质及草质的小、中高位芽植物组成为特征。群落垂直结构复杂 ,可分为乔木层、灌木层和草本层 ,并有一定数量的层间植物。乔木层物种多样性指数偏低 ,垂直结构各层次间物种多样性大小依次为灌木层 >乔木层 >草本层。Castanopsis eyrei forest was one of the main forest types in Gutianshan Nature Reserve. The study results showed that it was characterized by microphanerophytes and mesophanerophytes with microphylls and mesophylls, simple, unentire, leathery and herbaceous leaves. The Castanopsis eyrei community had a striking mone dominant character. The complicated vertical structure could be divided into tree layer, shrub layer and herb layer, as well as a definite number of interstratum plants. The species diversity index of the tree layer was a bit low, and the general trend was shrub layer > treelayer > herb layer.
