Abstract:: Taking carbon source and carbon sink into consideration in the process of the agricultural carbon cycle, we measured the regional agricultural net carbon during the period from 2000 to 2011. Based on the decoupling index model and evaluation criteria, we also measured the decoupling degree, explored the decoupling relationship and the internal mechanism between the regional agriculture net carbon and the economic growth. The results indicated that the total agricultural net carbon significantly increased in China during the period from 2000 to 2011. The carbon dioxide emissions increased from 237.30 million tons to 561.77 million tons, and the carbon sink capacity increased from 461.18 million tons to 568.46 million tons, correspondingly. Agricultural carbon emissions grew at the annual rate of 12.40%, meanwhile, total agricultural carbon sinks grew at the annual rate of 2.10%. The net carbon of the developed cities of eastern coast was higher than the national average level, and the agricultural economic growth rate was obviously different among different regions. The agricultural economic growth rate during the period from 2006 to 2011 was obviously lower than the period from 2000 to 2005. In the recent 10 years, it showed the weak decoupling between regional agriculture net carbon and the economic growth with the elasticity value of 0~1. The number of provinces that had the weak decoupling increased year by year, nearly accounting for the 90% of the whole provinces in China during the period from 2006 to 2011.
