Abstract: In order to research the differences in the resistance of varieties of trees, the Acer truncatum Bunge, Lagerstroemia indica L., Pteroceltis tatarinowii Maxim., Ulmus densa Litv. and Hibiscus syriacus L. seedlings were studied through the comparison of their drought tolerance, salt tolerance and moisture tolerance and a comprehensive evaluation on resistances of 5 varieties was given based on subordinate function values analysis. The results showed that: there was a deep difference in the resistance of varieties of trees, a comprehensive evaluation on the ability of resistance of the varieties of trees was Lagerstroemia indica L.> Ulmus densa Litv.>Hibiscus syriacus L.>Acer truncatum Bunge>Pteroceltis tatarinowii Maxim.
