| 摘 要： | 选取两个典型样地对金佛山甑子岩植被演替与恢复进行动态监测,结合稀疏曲线法、丰富度指数、多样性指数和均匀度指数法分析比较了两样地植物群落的物种丰富度、多样性和均匀度。研究表明:①位于陡岩区的样地植被生长和恢复状况良好;而位于平缓区的样地,受采矿等相关活动干扰较大,植被恢复过程中出现了逆行演替,在得到一定的保护后,群落演替由逆行演替又渐渐恢复到正常的顺行演替之中。②离人居地较远的样地,植物群落的丰富度、多样性和均匀度指数越高,稀疏曲线越陡峭;而离人居地较近的样地则相反。③人为影响对上述地区植物群落的影响非常大,应加大甑子岩生态环境管理力度,尽可能减少对植被的破坏,重视退化区的植被保护与恢复重建工作。

| Abstract: | Two typical sample places in the Jinfo Mountain were chosen to carry on the dynamic monitor of vegetation evolution,and then with the method of rarefaction curve,species richness,species diversity and evenness,species richness,diversity and evenness were analyzed in communities of Zengziyan in Jinfo Mountain.The results were as follows:①The growth and restoration of vegetation was good when it was located in the steep region.②There were lower species richness,species diversity evenness in this region,which was nearer to the residential and which was lives in the lower elevation.③The serious degradation of plant community succession of Zengziyan was analyzed because of over-graze and denudation timber mining.More attentions should be paid to managing mining area,controlling pollution,protecting plants,and recruiting the degenerating vegetation. |
