Abstract
将豫东平原农区5 a、9 a、11 a和13 a 4个林龄阶段的杨树-农作物复合系统分为林木、农作物、凋落物和土壤4个子系统,分别研究其碳贮量.结果表明:5 a、9 a、11 a和13 a杨树-农作物复合生态系统林木及凋落物的碳贮量分别为7.86、42.07、44.31和60.71 t·hm~(-2);间作作物平均每年可吸收CO_2 6.8 t·hm~(-2);农田土壤碳贮量分别为45.55、51.06、55.94和60.49 t·hm~(-2);杨树-农作物间作系统的总碳贮量分别达60.81、100.09、106.76和127.34 t·hm~(-2),远高于单作农田(49.36 t·hm~(-2)).各年龄阶段杨树和土壤碳贮量占总碳贮量的比例最大,在87.1%～93.1%,而农作物和凋落物碳贮量比例较小,占总贮量的6.9%～12.9%.说明农林复合生态系统具有很强的吸收和固定碳的能力.
