方山中山丘陵区植物多样性研究

Plant species diversity in hilly regions of Fangshan Mountain.

以方山地区27个样方的调查资料为基础,从物种种类组成的相似性,不同层次的物种丰富度,物种多样性等方面对方山植物多样性进行分析。结果表明,该地区乔木层物种丰富度较低,而灌木层和草本层较高;该地区物种多样性随海拔高度的升高而降低;在同一海拔高度上,北坡的物种多样性大于南坡;人类活动对该地区植物物种多样性有明显影响。

Based on the investigation data of 27 sampling plots, the plant species diversity in the hilly regions of Fangshan Mountain was analyzed from the aspects of component similarity, and species richness in various layers. The results showed that the species richness was lower in tree layer, but higher in shrub and grass layers. The species diversity was decreased with increasing altitude, but was higher on northern than on southern slope at the same altitude. Human activity had a significant effect on the plant species diversity.
