摘　　要：以东北林业大学帽儿山实验林场生长的野生紫椴和哈尔滨城市生境中生长的紫椴(Tiliaamurensis)为研究对象,分别测量树高、胸径和枝下高。利用SPSS17.0统计软件进行分析,结果表明,通过不同环境下的紫椴胸径与树高的关系可以看出,市区环境下生长的紫椴高生长与野生的紫椴高生长曲线相似。引种第1年,市区紫椴高生长略弱于野生紫椴,而后逐渐适应城市生境。市区生长的紫椴与野生紫椴枝下高的生长规律在第3年以后基本一致。紫椴可以大规模地作为绿化树种引入城市,适应周期为3a。The height, DHP and clear length of Tilia amurensis were measured. The data obtained were analyzed by SPSS 17.0. after it was transp tial than in natura anted in urban areas. In the first year of trans both in urban and natural environments It was found that T. planting, it exhibited arnurensis grew well lower growth poten- environment. But the growth tendency of the trees growing in natural environment and urban areas was similar in the third year. It was concluded that T. amurensis could be transplanted in ur ban areas in large scale, which could adapt the new environment after 3 years of transplanting.
