摘 要：
对广东内伶仃岛群落受薇甘菊危害的植物种类分析表明,58种乔木、小乔木和灌木种不同程度地受薇甘菊的影响,约占样地中木本种类的67%;其中受薇甘菊影响最大的主要是小乔木和阳生性灌木.薇甘菊危害与群落类型的关系表现为,由5、6个优势种组成的结构复杂的具有较大郁蔽度的群落受薇甘菊的危害轻微,而仅由2个优势种组成结构简单且郁蔽度很小的群落受薇甘菊的危害较严重.薇甘菊危害与群落结构的相关分析表明,群落垂直高度越大、片层越丰富,群落中薇甘菊的盖度越小;群落物种越丰富,群落密度越大,个体受害比例越小;群落中其他藤本盖度越大,个体受薇甘菊危害的程度越高.

摘 要：
The analysis showed that 58 species of trees,short-trees and shrubs in Neilingding Island of Guangdong Province were damaged by M.micrantha,of which,woody trees accounted for 67%.Short-trees and sunny shrubs were damaged most seriously,followed by the communities with low canopy density consisted of only 2 dominant species,and those with high canopy density consisted of 5 or 6 dominant species.The coverage of M.micrantha mainly related to the vertical structure of plant communities.The taller the community height and the more the synusia,the lesser was the coverage of M.micrantha.The damaging ratio mainly related to species diversity and community density.The higher the species diversity and community density,the lower the damaging ratio was.The damaging degree mainly related to the coverage of other liana.The more the coverage of other liana,the higher was the damaging degree of M.micrantha.
