稀有花卉植物猬实在华山地区的种群繁育和分布特征

Protected research on sparsity flower Kolkwitzia amabilis on the Huashan Mountain

通过对稀有花卉植物猬实在华山地区的种群分布特征研究,对其植物群落物种的种类组成、区系特征及其目前猬实的分布进行了调查与研究,分析了猬实的逐渐濒危的原因.结果表明,猬实分布区植物群落区系属于北温带性质;猬实在华山从低海拔到高海拔地区均有分布,但个体数目少,呈明显的斑块状分布;在小范围内的克隆繁殖使得其后代生存力下降,在群落中缺乏竞争能力;再加上猬实生存的环境已受到严重的破环,使得其处于濒危状况,因此,我们要加强对其环境的保护.

This paper analyses the factors of threaten Kolkwitzia amabilis graebn.Through study on its ecological and biological characteristics and the distribution of at present,study on the dangerous factors.The most important factor was the survivorship conditions that were destroyed by human activities.Another factor was the special system of breeding,clone breeding in the small range made viability and seed rate of its descendant was come down,and being short of competition on the community,made its locate the condition of dangerous Therefore,we need to protect its conditions.
