摘　　要：以天津市静海县轻中度盐碱地上的9种灌木为试材,对年均株高、茎粗、叶幕厚度和冠幅等进行了研究,比较了常见灌木和小乔木的耐盐性。结果表明：9种灌木中,忍冬的年均株高最高,为1.43m,其次是红宝石海棠,为1.15m;西府海棠、丁香、金银木、美人梅年平均株高最低,为0.39-0.58m;红宝石海棠的年均茎粗增长量最高,为2.61cm,榆叶梅最低,为0.49cm;西府海棠的叶幕厚度最高,为3.28m,丁香、忍冬、金银木、榆叶梅叶幕厚度最低,为1.23-1.61m;红宝石海棠、紫叶李、紫叶矮樱、美人梅的冠幅最高,为2.04-2.33m,丁香、榆叶梅的冠幅最低,为1.12-1.42m。9种灌木的叶幕厚度、冠幅和年均茎粗增长量的变化呈一定程度的正相关（相关系数0.53-0.67）,但与株高无关;根据各指标的隶属函数综合分析认为,盐碱地上9种植物的生长表现依次为红宝石海棠〉紫叶矮樱和紫叶李〉忍冬、西府海棠和美人梅〉金银木和丁香〉榆叶梅。In order to compare salt tolerance of common shrub and small trees,the annual plant height,stem diameter,leaf thickness and the crown of 9species 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（1.43meters）,the second was ruby haitang（1.15m）,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（2.61cm）and was the shortest in flowering plum（0.49cm）.Canopy was the thickest in midget crabapple（3.28m）and was the thinnest in clove,honeysuckle,amur honeysuckle,flowering plum（1.23-1.61m）.Crown width was the highest in ruby haitang,prunus cerasifera,Prunus×cistena,Prunus mume ‘Meiren＇（2.04-2.33m）,was the lowest in clove and flowering plum（1.12-1.42m）.Canopy thickness,crown width and annual stem diameter of 9kinds 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 9species was followed by ruby haitangPrunus×cistenaand Prunus cerasiferahoneysuckle,midget crabapple and Prunus mume‘Meiren＇amur honeysuckle and cloveflowering plum on saline-alkali land.
