Biomass and carbon storage of ground bryophytes under six types of young coniferous forest plantations

Abstract

Abstract: This paper studied the biomass and carbon storage of the ground bryophytes under young Picea balfouriana (P),Pinus tabulaeformis (Y),Pinus armandii (H),Larix kaempferi (L),Picea balfouriana-Pinus tabulaeformis (P-Y),and Pinus tabulaeformis-Pinus armandii (Y-H) forest plantations in the upper reach of Minjiang River,Sichuan Province.The results showed that total biomass and carbon storage of ground bryophytes were relatively low,being 3.11～460.36 kg·hm^-2 and 1.12±0.03～168.95±0.92 kg·hm^-2,respectively.On plot level,only the bryophyte biomass between forest P and others,and the carbon storage between forest L and others were significantly different.The ground bryophyte had the highest biomass and carbon storage under forest P,while the lowest ones under forest H.Comprehensive analysis suggested that forest type and its structural feature might be the important factors determining the biomass and carbon storage of ground bryophytes,and thinning was an important measure to improve ground bryophyte growth and biomass production.

Key words: Artificial forest, Bryophyte biomass, Carbon storage, Ecological restoration
