Abstract: In order to promote the protection,development and utilization of local tree species in the application of garden plants in urban parks of Yinchuan City,according to the standard of park green space division,9 city parks with 3 different types in 3 districts of Yinchuan city were selected.By means of field investigation and consulting the relevant park plant configuration data and geographical location data,the park garden plant configuration types,distribution status and configuration structure were analyzed,as well as the maintenance status and other aspects of the investigation.The results showed that,there were 134 species of main garden plants in urban park of Yinchuan City,belonging to 62 families and 103 genera;among them,Rosaceae plants were widely used,with a total of 16 species;there were 75 species of native tree species,59 species of introduced tree species,with a ratio of 1.3∶1.0;from the ornamental effect of garden plants in urban park of Yinchuan City,there were 79 species of ornamental trees and shrubs.Based on the results of investigation and analysis,it is suggested that the application of Rosaceae plants should be promoted in the future development of urban parks,and Elaeagnus angustifolia and other local characteristic tree species should be recommended,while Platycladus orientalis and Populus tomentosa should be the backbone tree species for urban park landscaping.In addition,we should strengthen the use of trees with strong resistance and special ornamental value,increase the diversity of garden plants in urban parks,increase evergreen tree species,optimize the structure and composition of tree species,strengthen the cultivation of garden plants,explore local tree species,and enhance regional characteristics.
