Abstract:

Flower boarder plays an important role in constructing urban road landscape. Application status of flower boarder in 18 urban roads in Qinhuangdao was surveyed and analyzed by field investigation. The results were showed that: (1) the flower border plants was 57 species, belonging to 27 families and 51 genus, including 16 species, 26 families and 30 genus in central reservation, and 25 species, 46 families and 50 genus in basic green belt; (2) for flower border type, major mixed border and perennial border were found at central reservation. The 4 types including perennial border, mixed border, shrub border, and one or two-growing seasons border were found at basic green balt, but the first two type was dominate. Based on this situation, some recommendations were presented to strengthen introduction and domestication, and strengthen regional characteristics, increase the applications of hardiness and frost plant, and optimize the species structure of flower border.
