摘  要：
对14年生I-72杨人工林生长特性进行的研究结果表明,其生长过程大致可以分为3个时期:1~4 a为幼林期,5~10 a为速生期,11~14 a为近熟期。I-72杨树高速生期为3~8 a,胸径速生期为5~10 a,材积速生期为6~10 a。树高生长要早于胸径生长,林木的后期生长以胸径和材积生长为主。树高和胸径的连年生长量最大值比平均生长量最大值的到来时间要早,树高连年生长量大约在第7年生时与平均生长量相交,胸径连年生长量和平均生长量大约在第9年生时相交,材积连年生长量和平均生长量在14 a中未能相交,即没有达到数量成熟,其合理的轮伐期应在14年生以上。单株之间树高生长的竞争主要集中在第3~8年生时,胸径和材积生长竟争集中在生长后期。用R ichards方程对I-72杨的树高、胸径和材积进行拟合,拟合效果很好。

摘  要：
The study on forest growth characteristics was conducted on Populus×euramiricana cv.'San Martino'(I-72/58)on beach land of Yangtze River.The results indicated:Populus×euramiricana cv.'San Martino'(I-72/58)growth process could be divided into 3 stages: 1—4 a was the young stand stage,5—10 a was the fast-growing stage,11—14 a was the near mature stage.The fast-growing stage of tree height was in 3—8 a,that of the breast diameter was in 5—10 a,and that of the timber volume was in 6—10 a.Populus×euramiricana cv.'San Martino'(I-72/58)' tree height grew earlier than the breast diameter,and Populus×euramiricana cv.'San Martino'(I-72/58)' later period grew by the breast diameter and timber volume growth primarily;Compared to the mean annual increment maximum,the current annual increment maximum of the tree height arrived much more earlier,so as the breast diameter;The current annual increment of tree height was intersected with the mean annual increment in about 7 a,the current annual increment and mean annual increment of the breast diameter intersected in 9 a;The current annual increment and the mean annual increment of the timber volume was not able to intersect in 14 a,that means that the Populus×euramiricana cv.'San Martino'(I-72/58)'growth process could not reach its quantitative maturity period,its period was in 14 a.Competition of the tree height among individual trees was primarily in 3—8 a;Competitions of the breast diameter and timber volume among individual trees were primarily in later period.With the Richards equation was used to fir the breast diameter,the tree height and the timber volume of Populus×euramiricana cv.'San Martino'(I-72/58),the fitting effect was excellent.
