Abstract

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．

Key words: Chinese fir, Young plantation, Shrub stratum, Herb stratum, Forest litter, Biomass
