摘 要:
对具有不同驳岸方式（鹅卵石堆砌驳岸、自然泥岸、石砌驳岸和砼仿木桩驳岸）景观河道水陆交错界面上覆水质及界面水生生物多样性进行了定量研究。结果表明：泥岸与卵石堆砌驳岸界面上覆水质总体优于石砌驳岸和砼仿木桩驳岸方式；泥岸与卵石堆砌驳岸方式所营造的生态环境更适于界面浮游生物的生存、栖息和繁衍，特别是浮游动物；泥岸着生生物多样性优于其他驳岸方式；卵石堆砌驳岸虽相比其他两种非生态界面有一定优势，但并不明显，这与卵石表面坚硬，不利于水生生物附着有关。因此，近自然的泥岸和卵石堆砌驳岸方式更利于保持水生生物多样性并有较其他驳岸方式更好的水质净化作用。[著者文摘]

Abstract:
Four kinds of embankments in a sight river,i, e. , cobblestone bank, mud bank and other two concrete banks, were selected. The upper water quality and the diversity of aquatic organisms at the interface between the river and the riverbank were studied. The statistical results showed that the upper water quality of cobblestone bank and mud bank was better than that of the concrete banks, especially the suspended solids parameter. The ecological environment around the mud bank and cobblestone bank was more suitable for plankton to survive, especially the zooplankton. The diversity of inserted organisms at the interface of mud bank was excelled to other kinds of embankments. The cobblestone bank was not easy for the aquatic organisms to attach for such a hard surface.[著者文摘]
