Abstract:: The pot experiments were conducted to investigate the changes of 4 shelterbelt tree species growth and physiological characteristics under water-salt stress. The results showed that during the whole growth period, the growth rate of seedling height and collar diameter, biomass accumulation were obviously different. With the stress level and testing time increase, relative penetrability, chlorophyll, soluble protein, SOD activity, and Pro content presented the trend of first increasing then decreasing, while MDA content was continuously increasing. But water-salt stress level and response time were significantly different among all the tree species. Through principal component analysis (PCA), seedling height, collar diameter, biomass, relative penetrability, Pro content were used as the main factors to select shelterbelt tree species. Based on this evaluation system, the tolerance ability under water-salt stress of tree species was in the order of Sapium sebiferum > Taxodium distichum > Camptotheca acuminata > Koelreuteria paniculata.
