| 【目的】研究广州市车陂涌华南农业大学河段河岸带的草本植物群落特征，为城市河岸带生态功
能的恢复和保护提供理论依据。【方法】采取线路踏查与样方调查相结合的方法，获取样方内草本植物种类和
盖度等指标，计算群落内物种的重要值和多样性指数，分析群落结构特征。【结果】广州市车陂涌华农河段河
岸带的草本植物群落共有植物 60 种，隶属 28 科和 54 属，科属分布较分散。菊科植物占 18.33%，白花鬼针草（Bidens
pilosa var. radiata）是该群落的优势种。本土植物 40 种，外来植物 20 种，外来入侵植物 11 种。群落 ShannonWeiner
指数、Simpson 指数和 Pielou 均匀度指数分别为 2.66、0.86 和 0.71。【结论】广州市车陂涌华农河段河
岸带的草本植物群落物种组成较丰富，少数科属多样性突出，群落结构不稳定；外来入侵植物占优势，存在外
来物种入侵风险；建议选用本土植物优化河岸带植被结构，开展入侵植物防治工作。 |

| 【Objective】The characteristics of herbaceous plant community in the riparian zone along the reach
of Chebei River in South China Agricultural University in Guangzhou were studied to provide a theoretical basis for the
restoration and protection of the ecological functions of the urban riparian zone.【Method】Taking the methods of line
inspection and sample plot investigation， the indexes of species and coverage of herbaceous plants in the sample plots were
obtained，the importance value and diversity indexes of species in the community were calculated，and the community
structure characteristics were analyzed.【Result】There are 60 species of herbaceous plants in this riparian zone，
belonging to 28 families and 54 genera，and the distribution of families and genera is relatively scattered. The compositae
plants accounted for 18.33%, and Bidens pilosa var. radiata was the dominant species in this community. There were 40
species of native plants，20 exotic plants and 11 invasive plants. The Shannon-Weiner index，Simpson index and Pielou
evenness index were 2.66，0.86 and 0.71，respectively.【Conclusion】The species composition of the herbaceous plant
community in the riparian zone is relatively rich, the diversity of a few families and genera is prominent, and the community
structure is unstable. The invasive plants predominate and there is a risk of the increase of invasive species. It is suggested to
select native plants to optimize the plant structure of riparian zone，and carry out prevention and control of invasive plants. |
