摘    要:通过对西南部分地区紫茎泽兰入侵的群落学调查,研究了紫茎泽兰入侵的群落主要数量特征的变化规律.结果表明:紫茎泽兰入侵的群落其物种比较贫乏,最多的物种数量为17种;群落内紫茎泽兰主要数量特征随着物种数量的增加总体表现为下降的趋势,物种数目多的群落内,紫茎泽兰种群的优势度小,相对高度和盖度也比较低;优势度指标与群落多样性指数相关性最强,能反映出该入侵种对群落多样性、均匀性的影响.

关 键 词:生物入侵  紫茎泽兰  群落特征

Abstract:The coenology of invasive Ageratina adenophora was investigated in some southwest regions to study the change regulation of main quantity characteristics.The results showed that the species of the community invaded by Ageratina adenophora was poor and the highest species quantity of the community invaded by Ageratina adenophora was 17,the main quantity characteristics of Ageratina adenophora in the community showed a decline trend with species increase in the community,the superiority,relative height and co...
Keywords:biological invasion  Ageratina adenophora  community characteristics
