摘要
在样方法获取全面资料并用数量方法确定森林群落类型的基础上，对雾灵山国家自然保护区各森林群落的物种多样性（Ｄ）、生态优势度（Ｃ）、群落均匀度（Ｊ）等指标进行了计测；并着重对物种多样性进行评价，分析了物种多样性变化的时空规律，就物种多样性的保护与持续利用进行探讨。分析结果表明：雾灵山国家自然保护区森林群落物种多样性比较丰富，其Ｄ值在２３７～４１７之间；在特定高度范围内，随海拔增高Ｄ值增大，Ｃ值变小；多数森林群落灌木层的Ｄ值高于乔木层，Ｃ值低于乔木层；地带性群落的Ｄ值大于非地带性群落。
The present paper deals with the species diversity feature of forest in Wuling Mountain Natural Reserve in Hebei Provice,China.The species diversity of 7 forest communities are measured.The results show that the species diversity index is 2.37～4.17.According to further research of the measured results,the use and the effect as well as the ecological meaning of the species diversity,ecological dominance and the evenness index are explored.
