摘要
以广西国有高峰林场48年生木荷(Schima superba)人工林为研究对象,探讨其生物量及生产力。结果表明,木荷人工林单株生物量为81.61~576.12 kg;总生物量为281.79 t/hm^2,其中乔木层、林下层分别为268.71和13.08 t/hm^2,占比分别为95.36%和4.64%;乔木层生产力为7.77 t·hm^-2·a^-1,占林分总生产力(7.89 t·hm^-2·a^-1)的98.48%。
Based on 48-year-old Schima superba plantation in Guangxi state-owned Gaofeng forest farm,biomass and productivity were researched.Results showed that individual biomass of S.superba plantation was 81.61-576.12 kg and total biomass was 281.79 t/hm^2,of which biomass of arbor layer and understory layer were 268.71 and 13.08 t/hm^2 respectively,accounting for 95.36%and 4.64%of total biomass.The productivity of arbor layer was 7.77 t·hm^-2·a^-1 accounting for 98.48%of total productivity(7.89 t·hm^-2·a^-1).
