摘  要:
对松材线虫入侵不同年数后嵊泗海岛黑松林生态系统的植被分层情况、种类丰富度、多样性指数、均匀度指数、生态优势度以及优势种类植物等进行了调查和分析,结果表明:松材线虫对嵊泗海岛松林生态系统造成较大的破坏,为害后,原来生态系统中上层乔木消失,植被逆行演替为以野桐、算盘子、小槐花及一年蓬、禾本科植物及莽草为主的杂草和灌丛。随为害时间的增长,群落的组成和结构也有一定变化,生态系统整体处于次生演替的早期阶段。

摘  要:
Investigation and analysis was carried out on the layers of vegetation, the index of species richness,individual number, diversity index, evenness index, ecological dominance, and importance value of dominant species of Pinus thunbergii forest in Shengsi Islands, Zhejiang province, invaded by Bursaphelenchus xylophilus in different time. The results showed that the forest was seriously damaged by B.xylophilus. The upper tree layer in the former ecosystem disappeared, and the vegetation was in the retrogressive succession, which consisted of some herbage and shrub. As time went by, the component and structure of the community varied, and the ecosystem was in the initial stage of secondary succession.
