Abstract采用静态箱-气相色谱法观测了我国南方亚热带水稻田转为旱作蔬菜地后第1年的CO_2和CH_4通量变化,旨在探索稻田转菜地初期对CO_2和CH_4通量的影响.结果表明:CO_2通量因蔬菜种类、生长状况及生长季节的不同而不同.种植豇豆菜地CO_2通量显著高于稻田,种植辣椒菜地CO_2通量则显著低于稻田.稻田转菜地CH_4通量从6.96 mg C?m~(-2)?h~(-1)显著下降到-0.004 mg C?m~(-2)?h~(-1)(P<0.001).转菜地后CO_2和CH_4的净累积碳吸收为543kg C?hm~(-2),显著低于稻田的3641 kg C?hm~(-2),但由净CO_2和CH_4排放造成的增温效应无显著差异.转成菜地1年后的土壤有机碳含量有所升高,且10~20 cm土层显著高于对照水稻田.
