| 摘 要： | 通过对赣江流域河岸带植物调查,发现该地有外来入侵植物17科27属31种,其中菊科最多有9种。对赣江流域河岸带入侵植物分布的分析显示:外来入侵植物发生在赣江全流域,上、中、下游河岸带植物群落中入侵植物的优势度无明显差异;河岸带植被类型对入侵植物的分布影响较大,草本群落和灌草群落中的入侵植物优势度明显高于乔木林群落;干扰对外来植物的入侵起到了积极作用,与无干扰方式下的群落相比入侵植物的优势度差异极显著,但干扰方式对入侵植物的分布无影响。

| Abstract: | Survey on invasive plants in riparian zone of Gan River was conducted on the basis of three aspects of river basin,vegetation community and interference manners.There exists 31 species of invasive plants belonging to 27 genera in 17 families.Among them,Compositae is the most consisting of 9 species.There is not significant difference in the dominance of invasive plants among up-,mid-and downstream of riparian zone in Gan River.However,the distribution of invasive plants has been significantly effected by ve... |
