| 摘 要： | 研究了广西壮族自治区南宁市8年生黑木相思(Acacia melanoxylon)人工林生态系统的生物量、碳贮量及其分布特征。结果表明:黑木相思人工林生物量为108.47 t.hm-2,其中乔木层占总生物量的85.85%、灌木层占7.26%、枯枝落叶层占4.47%、草本层占2.42%。黑木相思人工林生态系统总碳贮量为143.06 t.hm-2,其中乔木层为46.33 t.hm-2,占整个生态系统碳贮量的32.39%;灌草层为4.78 t.hm-2,占3.34%;凋落物层为2.26 t.hm-2,占1.58%;林地土壤(0～60 cm)为89.69 t.hm-2,占62.24%。黑木相思人工林乔木层年净生物量增长量为17.02 t.hm-2.a-1,年净固碳量为8.45 t.hm-2.a-1,折合成CO2为30.98 t.hm-2.a-1。 |

| Abstract: | A survey was conducted to study the spatial distribution of biomass and carbon storage in an 8-year-old Acacia melanoxylon plantation in Nanning of Guangxi Zhuang Autonomous Region.Results showed that the total biomass of the A.melanoxylon plantation was 108.47 t·hm-2,of which the arbor layer showed the highest percentage(85.85%),followed by shrub layer(7.26%),litter layer(4.47%),and herb layer(2.42%).The total carbon storage in the A.melanoxylon plantation ecosystem amounted to 143.06 t·hm-2,of which the carbon storage values of the arbor layer,shrub layer,litter layer,and forest soil were 46.33,4.78,2.26,and 89.69 t·hm-2,accounting for 32.39%,3.34%,1.58% and 62.24%,respectively.The annual net productivity of the A.melanoxylon plantation was 17.02 t·hm-2·a-1,and the annual carbon storage was up to 8.45 t·hm-2·a-1,which is equivalent to 30.98 t CO2·hm-2·a-1. |
