摘　　要：对辽北彰武县四合城镇沙地人工栽培的元宝槭解析木进行了分析,结果表明:元宝槭的径生长在第4~16年增长较快;树高生长在第1~7年生长较快;材积平均年生长量和材积连年生长量在52年以前呈现较为均匀的生长过程,没有达到数量成熟。结合当地现存的多株100年以上的元宝槭古树情况,说明元宝槭的寿命超过100年。This paper analyzed the analytical wood of Acer truncateum Bunge cultivated artificially in the sandy land of Sihecheng town,Zhangwu county,Liaoning province,the results showed that the diameter growth of Acer truncateum increased rapidly from 4 to 16 years,and the height growth of tree increased faster from 1 to 7 years.The average growth of volume and the successive annual growth of volume showed a relatively uniform growth process before 52 years,which did not reach the quantitative maturity.Combined with several existing ancient trees of Acer truncateum of more than 100 years,it showed that the life of Acer truncateum was more than 100 years.
