独特的丹霞地貌将长时间的完整演替系列完好地展现于同一个时空中,为原生演替研究提供了一个理想场所。本项研究采用时空替代法,在泰宁丹霞地貌的状元岩景区,以山顶和崖壁阳生性植被的原生演替系列群落为研究对象,从群落物种组成与变化、各系列群落之间的相似性、群落结构特征与动态变化和物种多样性变化等方面进行了探讨。主要研究结果如下: (1) 状元岩系列群落样方中共出现维管束植物61科125属142种,其中蕨类植物7科14种、裸子植物1科1种、被子植物53科128种。在物种组成上,以禾本科、茜草科和菊科为大科,三科植物占全部种数约19%;多数科为含1种、2种的单种科和寡种科,占了全部科数的73.61%,表明...Succession study is one of the hot spots in the study of plant ecology. The newly emerged field of ‘restoration ecology’ has shown particular interest in the ideas of succession as the management and possible restoration of degraded habitat. As ecological restoration reference, it is meaningful for the vegetation restoration. But succession is a complicated process of long-time, especially primary...学位:理学硕士院系专业:生命科学学院生物学系_植物学学号:2162007115194
