武汉市高架桥下绿化现状及模式探讨

Discussion on Present Situation and Patterns of Greening Under Viaducts in Wuhan City

城市高架桥下的绿化已日益成为城市绿化的重要组成部分,高架桥下立地条件的特殊性给其绿化带来了一定的挑战。针对武汉市武昌、汉口、汉阳三个区域不同方向高架桥下的绿化景观展开了实地调查,并对绿化植物的种类、生长状况、绿化模式等方面进行了记录和分析。调查结果表明:武汉市高架桥下植物有33种,以耐阴灌木为主;主要采用灌木-草本地被的绿化模式。总体绿化植物比较丰富,但植物层次、色彩欠缺,绿化模式较为单一,且各高架桥之间植物景观变化不大。建议合理开发野生耐阴植物种类,因地制宜,营造丰富而多样的高架桥下植物景观。

Greening under the viaducts has increasingly become an important part of urban greening.The particularity of the environment under the viaducts brings some challenges to greening.Field investigations of the greening landscape under viaducts in different directions in Wuchang District,Hankou District,and Hanyang District in Wuhan City were made in this paper.The species,growth status,and greening pattern of the plants were recorded and analyzed.Results showed that 33 species of plants were under the viaducts in Wuhan City,mainly shade-tolerant shrubs,and a shrub-herbaceous ground cover greening pattern was used.The overall greening plants were abundant,but lack of plant levels and colors.The greening patterns were relatively single,and the plant landscape had little change among the viaducts.It is suggested to reasonably develop wild shade-tolerant plant species,adopt measures to local conditions,and create rich and diverse plant landscapes.
