中文摘要	以江西庐山剑叶金鸡菊(Coreopsis lanceolata)入侵群落为研究对象,调查了不同生境剑叶金鸡菊的克隆繁殖特性和群落特征。结果表明,生境资源水平高低对剑叶金鸡菊的克隆构型影响不显著,无论是资源贫乏的岩石还是资源丰富的弃耕地生境,剑叶金鸡菊依靠植株基部节处萌生的小芽体生长成密集丛生状,其游击型克隆构型变化与环境资源可利用水平高低无关。剑叶金鸡菊种群的伴生植物多为一些适应范围广的杂草,由于剑叶金鸡菊的密集型克隆生长的集团化生长策略,使其种群耐贫瘠和干旱能力非常强,因而适应不同生境的能力也非常强,这种生长策略使剑叶金鸡菊个体能快速扩增并排挤本土植物,形成大面积的单一优势种群影响当地的生物多样性。
英文摘要	The clonal reproductive property and community characteristic of invasive species Coreopsis lanceolata in different habitats in Lu Shan,Jiangxi province were studied.The results showed that there was no significant difference in clonal architecture under habitats with different resources.Whether in rock or deserted farmland,the clonal architecture was mainly phalanx which developed from the base of plant,it seemed that there was no correlation between the guerrilla clonal architecture and the level of environment resources.Those guerrilla clonal growth traits made C.lanceolata had collectivize growth strategy,which improved its resistance to barren and drought environment.Thus,naturalized C.lanceolata could dominate various indigenous plants in Lushan,the companion species of C.lanceolata populations were weeds with wider adaptability.
