分析了休宁县森林群落的类型、组成、结构和物种多样性,结果表明:休宁县的典型森林群 落为常绿阔叶林,但由于森林破坏,群落为成层现象和层片不甚明显;物种多样性指数(S、 D、H)是针阔混交林>常绿阔叶林>落叶常绿阔叶混交林>落叶阔叶林,低海拔>高海拔; 在同一类型不同层次中,灌木层>乔木层>草本层。

The type, composition, structure and species diversity of the forest community i n Xiuning county were analyed. It was found that the forest community in the cou n ty is a classic one, the evergreen broadleaf forest. But the layer phenomenon an d blade of forest was not obvious becaues of deforest action. The species divers ity ind ex(H′) showed needle broadleaf mixed forest>evergreen broadleaf forest>decidu ous evergreen broadleaf mixed forest>deciduous broadleaf forest, low altitude> high altitude. Within the same type, the species diversity inedx was shrub layer >tree layer>herb layer.
