The carbon sequestration and carbon footprint in the typical rice production system in Hunan province were ana- lyzed and compared by the principle of ecological economics. The results showed that carbon sequestration capacity of early rice, middle - season rice and late rice production system were 3 901.7,5 375.2,4 852. 3 kg C/hm2 , respectively. 1 kg e- conomic yield in three rice production systems were equivalent to fix O. 65,0.67,0.61 kg C ,respectively. Carbon footprints of production materials in the early rice, middle -season rice and late rice production system were 0. 172,0. 133, 0. ...
