Abstract:
The research is based on the situations that the species and regional characteristics of wild woody ornamental colored-leaf plants in landscape greening are few and weak, this study investigated the resources of wild woody ornamental colored-leaf plants in Tianmu Mountain and Qingliangfeng National Nature Reserve through field investigation and literature review. Using the Analytic Hierarchy Process (AHP), the selection of 150 species of wild woody colored-leaf plants in protected areas, and their application status and prospect were analyzed. The results are as follows: The results were divided into three grades: 26 species with high ornamental and landscape value, 77 species with relatively high ornamental and landscape value, and 47 species with low ornamental and landscape value. Through analyzing the present situations and prospects of its garden application, this paper put forward four principles for the arrangement of ornamental tree species: suitability for the colony, construction of a specific microclimate suitable for the color of the tree species, and a plant landscape with regional characteristics and cultural connotation respect for the venue and focus on the overall effect. Based on the above-mentioned four principles, in order to meet the needs of the city (town) green space ecological service function diversity and coordinated display, four types of urban green space, open space, park, three-dimensional, and road greening, were put forward in this study.
