Abstract: The values of stoichiometric properties of leaf C, N and P contents of 55 garden tree species in Fuxin city Liaoning Province, China were derived. The results showed that the C, N and P contents varied in ranges of 496-664, 7.5-26.6 mg•g^-1 and 1.0-2.2 mg•g^-1, and the C/N, C/P and N/P in ranges of 22.4-74.3, 262-522 and 5.4-13.8, respectively. Moreover, there was a significant correlation between leaf N and C/N or C/P （P<0.001). The leaf N and P contents and N/P of evergreen coniferous tree species were significantly higher than those of broadleaf deciduous tree species （P<0.05), but C/N and C/P of evergreen coniferous tree species were significantly lower than those of broadleaf deciduous tree species （P<0.05). The leaf N content and N/P of tree species were significantly higher than those of shrub species （P<0.05), but the differences in P content, C/P and C/P were not significant （P>0.05). These results revealed that the C storage capability and nutrient use efficiency of garden tree species were high.The garden tree species were Nlimited in the study area.
