摘　　要：杨树是我国北方造林绿化的主要树种,但由于抗盐碱能力较差,导致盐碱地区尤其是滨海重度盐渍区发展缓慢,人们担心杨树在该地区的长期适应性及其生长效果。作者对天津港区多年生的杨树绿地进行了全面调查,结果表明:①在客土绿化条件下,杨树生长表现良好,土壤盐害降低、肥力增强的变化趋势明显,提高了杨树在滨海盐渍区的长期适应性和稳定性。②毛白杨和欧美杨表现突出,年均生长量树高>1.1m,胸径>1.2cm;新疆杨冠幅小、生长量低、效益差。③杨树的生长状况与立地条件关系密切,毛白杨的年均生长量与土壤有机质呈显著正相关、与土壤全盐量呈显著负相关关系。因此,增加土壤有机质和降低含盐量的技术措施均能促进其生长,提高绿化效果。Poplar is the main tree species in afforestation in North China.The salt resistance ability of Poplar is poor which caused saline-alkali area especially Binhai severe saline area develops slowly.The long adaptability and growth effect of poplar is worrying in the region.There is a comprehensive survey to perennial poplar green of Tianjin Port in the paper,the results showed that： ① in the condition of the soil planting,the performance of poplar growth is good,soil salinization reduces,fertility changes obviously,it is implied that the long-term stability and adaptability of poplar is improved in Binhai saline area.②the performance of Poplar and Populus is outstanding,the average annual growth increment of tree height is 1.1m,Diameter at breast height is 1.2cm;the crown of Xinjiang Yang is small,growth quantity is low,benefit is poor.③The relationship between the growth of poplar and site conditions is close,the annual volume growth of Populus tomentosa had a significant positive correlation with soil organic matter,had a significant negative correlation with the total salt content in soil,technical measures,increasing soil organic matter and reducing salt content,can promote growth and increase the greening effect.
