CO_2 emission from the paddy ecosystem in subtropical region and its influence factors.

open access: yes, 2005
采用静态箱法对亚热带稻田生态系统CO2排放进行了定位观测.结果表明,水稻生长条件下的稻田CO2总排放通量(Rt)随晚稻生育期进程波动幅度较大,平均值为926.2mg/(m2·h);土壤CO2排放通量(Rs)则波动较小,平均值为285.4mg/(m2·h).二者与气温、不同土层(0,5,10,15cm)土壤温度均呈极显著的指数相关关系,温度系数(Q10)分别为2.33和1.70.稻田生态系统CO2累积排放量与水稻生物量间存在极显著的对数关系.在晚稻整个生育期 ...
