狼五山植物群落的生物多样性

Studies on the Plant Community Biodiversity in Lang Five Mountain

在对狼五山植被进行广泛调查的基础上 ,计算了各种类型植物群落的物种多样性和均匀度 ,并结合历史资料分析了植物群落的变化趋势。结果表明 :随着时间的推移和旅游业的快速发展 ,人类对生物多样性资源的干扰和利用逐步加强 ,植物群落的丰富度和均匀度都呈下降的趋势 。

The investigation of the plant community biodiversity in Lang five mou ntain was carried out and the various trend of biodiversity was analyzed in the paper according to history data. The results showed that there were decreasing t rend in the community species diversity and species evenness respectively, in di fferent communities and their three layers (arborous layer, shrub layer and herb aceous layer). The main reason was human's disturbance and over-use to biodivers ity resources.
