Abstract: 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.

Key words: Wuhan City, viaducts, greening status, greening patterns
