摘要
通过对国家三级保护植物猬实进行群落外貌和物种多样性研究,结果表明:猬实对生态环境要求不严,群落组成简单。3个分布区灌木层和草本层的物种丰富度、多样性指数和均匀度指数都表现为:山西永济雪花山>山西夏县泗交林场>陕西华阴华山。总结了影响猬实种群拓展的4个因素。
The physiognomy and species diversity of its plant community were studied for Kolkwitzia amabilis Graebn of the state third class protected plants. The results showed that the species could adapt to different conditions and was not strict with ecological environment and the plant community formed simple. The species richness, biodiversity indexes and evenness indexes of the shrub and herb layers in 3 distribution areas were as follows： Mr. Xuehua, Yongji, Shanxi〉Sijiao forest farm, Xiaxian, Shanxi〉Huashan, Huaying,Shaanxi. 4 limit expanding factors were summarized over this species community.
