摘要：20世纪70年代,著名植物学家Halle和Olde-man首次正式提出了树木的构筑型概念并总结出热带树木的23种构型模式,同时编制了分析热带树木构筑型的检索表开始了对植物构筑型比较系统的研究。
Based on plant architecture,this paper analyzes the morphological structure of four Cunninghamia lanceolata trees in different ages using statistical method.The results indicate that： the bifurcation ratios increases with the age;the branching angles of primary branches are mainly distributed from 50° to 100° while the secondary branches are mainly distributed from 50° to 80°;the azimuth of primary branches follows uniform distribution and the secondary branches mostly distribute in horizontal direction;Distance from a branch attachment region to its parent container has a good correlation with the branch length.Branch length has a great relevance to the number of sublevel branch.
