摘要：基于海南西部沿海台地区、北部平原区、东部沿海台地区和中部山地区共18个调查点54个尾细桉人工林样地调查数据,分析海南尾细桉人工林的生物量、碳贮量、固碳能力及其区域空间分布特征。结果表明:海南尾细桉人工林生物量平均为49.72t·hm-2,乔木层(85.10%)>凋落物层(8.08%)>林下植被层(6.82%);尾细桉人工林生态系统碳贮量平均为88.84t·hm-2,乔木层为20.55t·hm-2(23.13%),林下植被层为1.55t·hm-2(1.74%),凋落物层为1.93t·hm-2(2.17%),土壤层(0～100cm)为64.81t·hm-2(72.96%);尾细桉各器官碳贮量以树干最大,占乔木层碳贮量的52.81%;海南尾细桉人工林生态系统年净生产力平均为17.56t·hm-2a-1,年净碳固定量平均为8.43t·hm-2,折算成CO2量为30.91t·hm-2a-1;整个海南尾细桉人工林生态系统碳贮量为2958.37万t,年净碳固定量为280.97万t·a-1;从不同区域来看,中部山地区尾细桉人工林固碳能力达11.89t·hm-2a-1,远高于北部平原区(8.97t·hm-2a-1)、西部沿海台地区(7.18t·hm-2a-1)和东部沿海台地区(8.26t·hm-2a-1),北部、西部和东部区域间固碳能力差异不明显;除东部沿海台地区与西部沿海台地区之间碳贮量差异不大外,其他区域之间碳贮量差异明显,这种差异主要是由于土壤碳贮量差异引起的。
Based on the investigated data of 54 plots of 18 sites in the west coastal area,north plain area,east coastal area and central mountainous area of Hainan Island,the biomass,carbon storage,carbon sequestration and spatial distribution of eucalyptus plantations in Hainan Island,southern China were analyzed.The results indicated that the mean total biomass was 49.72 t·hm^-2,and the biomass distribution of the forest system showed such a sequence as：arbor layer（85.10%）litters（8.08%）undergrowth layer（6.82%）.The mean total organic carbon storage in the eucalyptus plantation ecosystem amounted to 88.84 t·hm^-2,of which there was 23.13%（20.55 t·hm^-2） stored in the arbor,1.74%（1.55 t·hm^-2） in undergrowth vegetations,2.17%（1.93 t·hm^-2） in litters,and 72.96%（64.81 t·hm^-2） in the soil（0-100 cm）.The stem had the biggest organic carbon storage of the total carbon storage in various plant organs,accounted for 52.81% of carbon storage in arbor layer.The mean annual net productivity of eucalyptus plantations was 17.56 t·hm^-2a^-1,with a mean annual stored carbon up to 8.43 t·hm^-2,amounted to 30.91 t CO2·hm^-2a^-1.The total organic carbon storage and sequestration of the eucalyptus plantations of Hainan Island was 2 958.37×104 t and 280.97×104 t·a^-1,respectively.The carbon sequestration of eucalyptus plantations in the central mountain area（11.89 t·hm^-2a^-1） was largely higher than other three areas,such as the northern plain area（8.97 t·hm^-2a^-1）,the western coastal area（7.18 t·hm^-2a^-1） and the eastern coastal area（8.26 t·hm^-2a^-1）.The three areas had no significant difference in the carbon sequestration.Except for the western coastal area and the eastern coastal area,the carbon storage among all other areas was significantly different,mainly because of their different carbon storage of soil.
