摘　　要：研究了武汉市后官湖绿道示范段的观赏植物种类,各观赏期物种的组成、各生活型植物的物种丰富度及乡土植物使用情况及植物配置方式。将绿道划分为出入口、中部景观节点、中部非景观节点和毗邻居住区用地4部分;绿道观赏植物中蔷薇科、豆科植物种类较多,有31个科只有1种植物;四季皆有景可观,但12月至2月间赏花植物少;落叶乔木物种远比其他生活型植物多,乔灌比1.7∶1,常绿落叶比1∶1.7;乡土植物物种数占总数的百分比低,为70%,木本的仅占55%。应均衡选用植物种类,增加乡土植物应用,营建近自然群落;植物配置则应突出自然郊野特色,满足功能需求,突出主题。对滨水绿道的植物景观研究和创建具有参考价值。Ornamental plant species planted in the demonstration greenway along Houguan Lake in Wuhan were studied from the aspects of the species composition in different ornamental seasons, species richness, indigenous species composition with different life forms and the plant arrangement. The greenway was con- sidered being composed of entrances, middle landscape nodes, middle non-landscape nodes, and locations along the residential district. There were more species in Rosaceae and Leguminosae than others,but only one species was found for 31 families. The greenway exhibited its ornamental values all the seasqns,but fe- wer flowering plants were found in December,January and February. There were much more species of de- ciduous trees,and the ratio of tree to shrub was 1. 7 ： 1, the ratio of evergreen to deciduous tree was 1 ： 1.7. Indigenous plants accounted for 70% of all the species,in which 55% were arboroid species. It was suggested that the plant landscape of waterfront greenway could be more perfect by the following methods. to apply species evenly,to arrange more indigenous plants, to build near nature community. The arrange- ment of plant species should emphasize natural suburb characters to meet the function requirements and to reflect the scenic spots＂ themes. To some extent, all of the above could make contributions to plant land- scape study and constitution of waterfront greenways.
