摘要
通过对多代杉木萌芽林强度间伐补栽细柄阿丁枫（留杉栽阔）和保留杉木多代萌芽林（对照）处理的生物量及营养元素组成的研究，结果表明：模式中杉木平均树高、胸径及单株生物量分别是对照杉木的１．２０倍、１．２４倍和１．２６倍。模式的生态系统营养元素贮量比对照的增加４．１７％，其中氮、磷、钾增加尤为明显。细柄阿丁枫平均木枝条、根系（特别是细根）生物量及其所占比例均比杉木的高，且细柄阿丁枫早期稍耐荫。细柄阿丁枫是杉木低产林分改造或与杉木混交优良树种之一。
Through intensive thinning of Chinese fir sprout forest passed many asexual generations,then replanting Altingia gracilipes at the same place reserving Chinese fir when planting broad_leaved tree,its biomass and nutrient element composition and reserved Chinese fir sprout forest which passed many asexual generations (the control) were studied,the result indicated:the mean tree height D.B.H and biomass of Chinese fir under the pattern were respectively 1.20 times,1.24times and 1.26times as those of the control.The nutrient element stock of the ecosystem under the pattern increased by 4.17%,compared with that of the control,and the increasement of N、P、K in that was specially distinct.the biomass and the proportion of branch and root system (especially little root) of Altingia gracilipes ,mean tree were both higher than those of Chinese fir's,and Altingia gracilipes was a little shade_bearing in the early time,thus, Altingia gracilipes is one of the tree species that would improve the poor_production stand and form the mixed stand of Chinese fir.
