摘要
以广西某林场12年生灰木莲人工林为研究对象,通过树干解析,找出了灰木莲人工林材积的生长规律,研究结果表明:灰木莲人工林林分蓄积的总生长量和平均生长量随着树龄的增加单调递增,当树龄达到12年时林分蓄积总生长量和平均生长量分别达到最大值,其值分别为170.10m3/hm2和14.17m3;灰木莲人工林林分蓄积的连年生长量曲线随着树龄的增长先呈上升后下降。
In this paper,a breakout for 12 years in guangxi state-owned forest farms manglietia plantation research object,through the tree trunks,find out the ash of manglietia plantation volume growth rule,The results show that:Totalstand volumeand average growthof Manglietia plantation forestmonotonically increasedwith the increase of tree age.when old reaches 12 years stand to accumulate the total increment and average growth rate reached maximum value,the values of 170.10m^3/hm^2 and 14.17m^3.Year after year and grey manglietia plantation forest stand volume increment in a curve as the growth of the old first rise then fall.
