摘　　要：滨水自生植物对城市生态环境的改善、生物多样性的提高、自然驳岸的建设、美丽乡村生态和水环境建设有着重要意义,具有广阔的园林应用潜力。本研究采用样方调查法,以广东惠州滨水景观为对象,对其自生植物种类组成、物种来源、生活型和出现频度进行调查,并对部分自生植物的园林应用潜力进行分析。结果表明,此次调查的滨水自生植物有31科70属76种,其中禾本科和菊科物种是其主要组成;乡土植物种类占59.2%,外来植物种类占40.8%,在绿化建设中可适当挖掘和应用适应城市环境的本土滨水自生植物;滨水自生植物中,草本植物更具优势,占总种数的82.9%;出现频度高于25.0%的植物种类有10种,包括苏里南莎草、巴拉草和鬼针草等。自生植物符合节约型城市园林建设的要求,有利于园林绿化可持续发展,苏里南莎草等10种滨水自生植物,其园林观赏价值高,对滨水生境适应性强,可作为未来城市滨水景观营造的植物素材。Waterfront authigenic plants are of great significance to the improvement of urban ecological environment,the enhancement of biodiversity,the construction of natural revegetation,the beautiful rural ecology and the construction of water environment,it has broad application potential in gardens.The species composition,species sources,life forms and occurrence frequency of authigenic plants were investigated in the waterfront landscape of Huizhou City,Guangdong Province by using the quadrate survey method,and the application potential of some authigenic plants was analyzed.The results showed that there were 76 species in 31 families,70 genus,among which Gramineae and Compositae were important components.Native plant species accounted for 59.2%,exotic plant species accounted for 40.8%,in the green construction should be appropriate to dig and apply the native adaptation to urban environment of waterfront authigenic plants.Among the waterfront authigenic plants,herbs were more dominant,accounting for 82.9%of the total species.There were 10 plant species with more than 25.0%frequency,including Cyperus surinamensis,Brachiaria mutica and Bidens pilosa.Authigenic plants meet the requirements of energy-saving urban landscape construction and are conducive to the sustainable development of landscape greening.10 kinds of waterfront authigenic plants with garden application potential were recommend,such as Cyperus surinamensis,which had high garden ornamental value and strong adaptability to waterfront habitats,and could become plant materials for future urban waterfront landscape construction.
