摘要
利用常规石蜡切片法，光学显微镜观察，对长白山地区不同海拔紫椴枝叶解剖构造进行观察并比较分析。结果表明：从600～1100m范围内紫椴的生长情况良好；紫椴一、二年生枝条和叶片的解剖构造都随海拔的升高呈现一定变化规律；海拔的变化对枝叶不同解剖构造影响不同；综合观察，700～900m之间应为紫椴在长白山地区的最适宜生长的海拔高度。
With the traditional paraffin section method, observed by optical election microscope, the anatomy structures of branches and leaves of Tilia amurensis in different altitude in Changbai Mountain was compared and analyzed. The results indicate ： the growth of Tilia amurensis was normal from 600 to 1 100 m; the anatomy structures of annual, biennial, branches and leaves of Tilia amurensis presents a definite changes; orderliness according to the changes of altitude ; the effect on the different structures of anatomy branches and leaves by altitude is different; the most suitable altitude height for the growing of Tilia amurensis in Changbai mountain was from 700 to 900 m according to observed synthetically.
