摘要:
<正>研究了江苏省里下河地区10年生I 69杨无性系(PopulusdeltoidesBartr.cv."Lux")人工林的碳储量及其动态。结果表明,林分总的碳储量为(136.2±15.9)(平均值±标准差)t/hm2,其中林木、林下植物、A0层以及土壤的碳储量分别为(74.1±8.3),(0.3±0.1),(1.9±0.2)和(59.9±14.2)t/hm2。10年生时林木碳的净生产力为(11.1±1.7)t/(hm2·a),凋落物归还量为(2.3±0.3)t/(hm2·a),土壤CO2释放量为(5.5±0.2)t/(hm2·a)。可见,I 69杨人工林具有较高的生物生产力和碳储量,发展杨树等速生丰产林能对大气碳循环起到积极的作用。
Abstract:
The storage and dynamics of carbon were evaluated in a 10-year-old poplar(Populus deltoides Bartr.cv."Lux") plantation in the Lixiahe region,Jiangsu province,China.The total carbon storages of the stand were (136.2±15.9)(mean±standard deviation) t/hm~2.The carbon storages of the trees,understorey plants,A_0 layer and soil were (74.1±8.3),(0.3±0.1),(1.9±0.2) and (59.9±14.2)t/hm~2,respectively.The net primary productivity(NPP) of the trees was (11.1±1.7)t/(hm~2·a),and the annual amount of litterfall was (2.3±0.3)t/(hm~2·a).The annual total carbon dioxide efflux measured in situ with a closed chamber method was (5.5±0.2)t/(hm~2·a).It was suggested that the carbon storage and the NPP in plantations of fast-growing trees such as the I-69 poplar clone were high and could play an important role in determining future concentrations of atmospheric carbon dioxide.
