Landscape can not only effectively improve the residents' living happiness, but also promote the improvement of the city's ecological environment. Among them, colored leaf plants are commonly used tree species in landscape design. Relevant designers are required to skillfully use them in order to enrich the landscape color and to better activate the landscape atmosphere. This paper analyzes the characteristics of color-leafed plants and discusses their application skills in landscape design in order to improve the quality and aesthetic feeling of urban landscape design.展开更多

So it is necessary for us to do much research for the development and utilization of this species. According to the latest existing research data of D. hongkongensis, the research achievements of D. hongkongensis in Germplasm resource distribution, bio-ecological habits, breeding and cultivation techniques and so on have been analyzed and summed up. On the other hand, its Ornamental value has been utilized in the modern landscape. At the same time, Edible and Medicinal value of D. hongkongensis has been discussed in the paper as well as Material value of D. hongkongensis. In addition, the future aspects of physiological and ecological research, domestication and breeding new varieties, resource protection and landscape application of D. hongkongensis have been proposed.展开更多
