    摘要:对长江流域地区武汉、上海、重庆3座城市中心城区的145座高架桥绿化现状进行了调查,对比三市高架桥绿化比率、植物群落结构、植物配置特点及设计特色。三市高架桥绿化比率武汉最低,为63.6%;上海最高,达到了90.9%。应用的植物共106种,隶属48科84属;植物群落灌—草最多,其次是乔—灌—草;在桥墩绿化、改善植物生境措施、配套基础设施方面各城市采用了一些特色设计,既实用又美观。通过对三市高架桥绿化的比较,为研究长江流域地区的城市高架桥绿化提供了依据和思路。

    Abstract:The greening situation of 145 viaducts situated in the Yangtze River region namely Wuhan, Shanghai, Chongqing were surveyed, including comparison of viaduct greening rate, plant community structure, plant arrangement and design features. Viaduct greening rate in Wuhan was the lowest, 63.6%; Shanghai got the highest, reaching 90.9%. Greening plants in three cities contained 106 species belonging to 48 families, 84 genera. Plant communities were mostly shrub-grass, followed by arbor-shrub-grass. There were some distinctive designs about pier greening, plant habitat improvement and supporting infrastructure in each city, which brought practical and aesthetic effects. By comparing viaduct greening in three cities, it provides the basis and idea for studying viaduct greening in the same climate type along the Yangtze River.
