为了探讨不同树种间抗逆性的差异，以华北五角枫、紫薇、青檀、榔榆、木槿1年生扦插苗为试验材料，对其抗旱性、抗涝性和抗盐性进行比较，并用隶属函数法进行综合评价。结果表明：不同树种间抗逆性差异较大，供试材料抗性强弱依次为：紫薇>榔榆>木槿>华北五角枫>青檀。
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.
