摘  要：
以定位监测和时空互代相结合的方法,于1998~2005年对广西国有东门林场不同连栽代次尾巨桉(Eucalyptus uro-phylla×E.grandis)人工林生长量、生物量和净生产量动态进行了连续8 a的研究。结果表明:在一个轮伐期内,尾巨桉林木胸径和树高生长量以1~5 a较快、5 a以后则减缓,呈现早期强速生特性,连栽会使这一特性更加明显;连栽林分(第2代)乔木层3.6 a、5.8 a和7.3 a的总生物量平均值分别为43.531 t.hm-2、84.127 t.hm-2和94.289 t.hm-2,除3.6 a的平均值比对照林分(第1代)的低5.36%外,其5.8 a和7.3 a的平均值则分别比对照林分的高7.79%和6.0%,但差异不显著;连栽林分和对照林分的干材生物量占总生物量百分率均随林龄的增加而增大,干皮、枝、叶和根所占的百分率则随林龄的增加而减小,其乔木层定期平均净生产量随着林龄的增加均呈现先增后减的趋势。

摘  要：
The growth,biomass and net output of Eucalyptus urophylla×E.grandis short-rotation plantation in Dongmen National Forest Farm of Guangxi were studied during 8 years from 1998 to 2005,using the methods of "time and space mutual substitution" and "fixed position monitoring".The results showed: the annual growth of diameter and height were much faster from 1a to 5 a,and more slowly after 5 a,and showed the strong-growing characteristics of early stage.The total biomass of 3.6 a,5.8 a and 7.3 a in the tree layer of continuous cropping stands were 43.531 t·hm-2,84.127 t·hm-2 and 94.289 t·hm-2 respectively,and decreased by 5.36% compared with the general biomass of the first generation in 3.6 a,but increased by 7.79% and 6.0% compared with the first generation in 5.8 a and 7.3 a respectively.To the continuous cropping and the control stand,the biomass ratio of dry wood to total biomass was increased with the increasing of stand ages,and the percentage of dry bark,branch,leaf and root was decreased with the increasing of stand ages.An average net output of stands in the arbor layer showed the early was increasing and the later was dropping.
