摘 要 ：对会同集水区第二代杉木幼林林下地被物生物量进行了5年的定位研究，探讨了杉木幼林林下灌木层、草本层和死地被物层的生物量动态变化。结果表明，杉木幼林林下地被物生物量为1.50-3.85t/hm²，并随林龄的增大，林下灌木层生物量明显减少，其生物量大小顺序为根>茎>叶，草本层生物量的大小顺序为地下部分>地上部分。

Abstract:The biomass of understory in the secondary generation of chinese fir stand has been studied for 5 consecutive years at Huitong watersheds．Biomass dynamics in understory shrubs，herbs and litters were discussed．The results showed that the biomass of under-story in young chinese fir stand was 1.50—3.85t/hm²,the biomass of shrub decreasedas the stand age increasing．The biomass order of shrub was root>stem>leaf，while the biomass order of herb was under ground part>aboveground part．
