摘　　要：对西双版纳普文试验林场的21年生高阿丁枫人工林进行了样地调查,选取平均木作树干解析,据此全面分析了高阿丁枫人工林幼中林期的直径、树高、材积生长过程以及林分状态、林木的年生长节律和结实状况,结果表明在此期间高阿丁枫人工林林木的树高生长旺盛期在3～5年,胸径在3～7年,材积在15年以后增长较快;林分中林木分化不明显;年生长期长.林分尚未进入数量成熟期.The sample plot of 21 years old plantation of Altingia excelsa situated in Puwen experimental forestry center in Xishuangbanna was surveyed. The average tree was selected for stem analysis. According to this, the growth processes of diameter, tree height and volume of timber, the state of forest stand, annual growth rhythm of the forest and the seed-bearing state of plantation of A.excelsa at the stage of young forest and half-mature forest were comprehensively analyzed. The results indicated during this time the peak period of tree height of plantation of A.excelsa is in 3~5 years, that of the diameter at breast height is in 3~7 years, the volume of timber increased relatively fast after 15 years, the tree differentiation in the stand is not clear, the stand had long annual growth period, and the stand had not reached quantitative maturity yet.
