安徽查湾自然保护区甜槠群落结构特征研究

Castanopsis eyrei community characteristics in Zhawan Natural Reserve of Anhui Province

甜槠林是査湾自然保护区常绿阔叶林主要类型之一。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。形成的群落类型为甜槠-马银花+暖木-狗脊蕨。群落垂直结构复杂,成层现象明显。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 is one of the main forest types in Zhawan Nature Reserve.The investiga-tion result showed that the Castanopsis eyrei community has a remarkable mono-dominant character.The com-munity is mainly composed of Castanopsis eyrei-Rhododendron ovatum plus Meliosma veitchiorum-Woodwardia japonica.The complicated vertical structure could be divided into tree layer,shrub layer and herb layer,as well as a definite number of inter-stratum plants.The species diversity index of the tree layer is low,and the general trend is shrub layer tree layer herb layer.
