Abstract: Constructing resource\|efficient landscape greening is an important part of the conservation\|oriented society construction， and selection of tree species is the key section for constructing resource\|efficient landscape greening. Ningbo and Luzhou， which are situated in the mid\|subtropics in China， were selected in this study. Tree species in these two cities were studied using the plant community survey method and analytic hierarchy process（AHP）， and 99 and 77 species of resource\|efficient trees were selected in Ningbo and Luzhou， respectively， including the main planting trees and shrubs. Considering the environmental adaptation， ornamental value， ecological benefit and application situation， there were several good strategies for the construction of resource\|efficient landscape greening， such as developing the local species， using a large amount of wild trees， rational allocation of trees and advocating the nursery construction.
