Abstract:: In order to compare salt tolerance of common shrub and small trees，the annual plant height，stem diameter，leaf thickness and the crown of 9 species plants were studied on mild and moderate saline soil in Jinghai County of Tianjin.The results showed that annual plant height of honeysuckle was the highest (1.43 meters)，the second was ruby haitang (1.15 m)，but annual plant height was the lowest in midget crabapple，clove，amur honeysuckle，Prunus Mume ‘Meiren’，which was 0.39-0.58 m.Annual diameter was the longest in Ruby haitang(2.61 cm) and was the shortest in flowering plum (0.49 cm).Canopy was the thickest in midget crabapple （3.28 m) and was the thinnest in clove，honeysuckle，amur honeysuckle，flowering plum (1.23-1.61 m).Crown width was the highest in ruby haitang，prunus cerasifera，Prunus×cistena，Prunus mume ‘Meiren’ (2.04-2.33 m)，was the lowest in clove and flowering plum (1.12-1.42 m).Canopy thickness，crown width and annual stem diameter of 9 kinds of shrubs was a certain degree of positive correlation (correlation coefficient 0.53-0.67),but they were irrelevant with annual plant height.According to the comprehensive analysis of the membership function，the plant growth of 9 species was followed by ruby haitang＞Prunus×cistena and Prunus cerasifera＞honeysuckle，midget crabapple and Prunus mume ‘Meiren’＞amur honeysuckle and clove＞flowering plum on saline-alkali land.
