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2.37~4.17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,C值相反。

Abstract

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.
