笔架山森林群落植物多样性之垂直分布研究
Study on Vertical Distribution of Plant Diversity in Forest Community in Bijiashan Mountain
为探讨海拔梯度对植物群落结构的影响,对设立在清远笔架山自然保护区的海拔 100m、300m、500m等3个海拔梯度森林群落的样地进行比较分析。结果表明:(1)三个不同海拔样地总共有 25科 84属 101种;(2)样方内物种的丰富度随着海拔的升高呈逐渐降低的变化趋势;(3)在物种多度分布方面,少数物种个体数很多,许多物种个体数很少。此研究对南亚热带退化林的植被恢复有重要意义,对垂直分布植物多样性研究有借鉴作用。
In order to investigate the 1effect of elevation gradient on plant community structure,three forest community plots with elevation gradient of 100m,300m and 500m were compared and analyzed in Bijiashan Nature Reserve,Qingyuan.The results showed as follows:(1)There were 101 species of 84 genera and 25 families in the three different elevations;(2)The species richness in the quadrat showed a decreasing trend with the increase of altitude;(3)In the distribution…查看全部>>
