摘要
对深圳市立交桥绿化植物种类及应用现状调查分析表明:在城区50座立交桥绿地中共记录了维管植物300种及变种,隶属76科209属。其中,乔木139种、灌木91种、草本46种、藤本13种、蕨类7种及竹子4种。在立交桥墙面、防护栏、桥柱3个立体绿化空间中,以墙面绿化比例最高,防护栏次之,桥柱最低。立交桥桥荫和立交绿岛的绿化和观赏效果良好,但立交绿地所应用的植物多为外来种,部分绿地的养护管理还有待加强。建议加强优良乡土植物的应用,促进立交绿地植物多样性和生态效益的提高。
The plant species and their application status in the green-space around 50 flyovers in Shenzhen City were surveyed. 300 species and varieties of vascular plants were recorded out of 209 genera, 76 families, including 137 tree species, 90 shrub species, 46 herbaceous species, 13 climber species, 7 fern species and 4 bamboo species. Among the three types of vertical greening structure, the vertical wall greening was the most common type, followed by fence greening and pillar greening. The greening and ornamental effect under the flyovers and in the surrounding green islands was generally good. However, most of the plant species applied were exotic, and the tending and management of some green-spaces were not so good. It was recommended to increase the application of native plant species, promote the maintenance and management of the green-space and improve the species diversity and ecological benefits of the flyover green-spaces.
