摘要
通过对广州市车陂涌河岸带人为干扰较少的5个河段的草本植物群落特征进行调查,分析河岸带的物种多样性和影响河岸带植被分布的主要因素,总结适宜广州河岸带生态护岸的草本植物。经统计,河岸带样方内共有草本植物57种,隶属于23科51属,禾本科与菊科植物最多,分别占10种和8种。本土植物47种,外来入侵植物10种,存在外来生物潜在入侵危险。群落结构复杂,物种组成繁多。结合生态护岸原则和调查结果,最终筛选出节节草Commelina diffusa、柔枝莠竹Microstegium vimineum、红尾翎Digitaria radicosa等10种本土植物作为生态护岸植物进行推广。
Through the investigation and analysis of riparian revetment community,the main factors that dominate the species diversities and vegetation distribution in riparian zone are explored.The author summarized 10 candidate herbaceous plants for ecological revetment in the riparian zone of Guangzhou as a suggestion.There are 57 species of herbaceous plants belonging to 51 genera of 23 families in the quadrat,and the most commonly distributed are gramineae and compositae,accounting for 10 species and 8 species respectively.There are 47 native plant species and 10 alien invasive plant species.There is potential invasion risk of alien organism.The community structure is complex and the species composition is various.Finally 10 native plants were selected to be used as ecological revetment plants,including Commelina diffusa,Microstegium vimineum,Digitaria radicosa.
