- Abstract:
-
Agriculture has become one of the main sources of carbon emissions in the world, which has attracted worldwide concern. Based on the input of chemical fertilizers, pesticides, agricultural plastic films, power consumption and diesel, carbon emissions of Chongqing in recent15 years from 1996 to 2010 was estimated.The results showed that:(1) in recent 15 years, carbon emissions due to agricultural investment were in obvious growth trend, presenting in three stages: sluggish growth stage of growth decline, the fluctuation of growth stage and rapid growth stage;(2) in recent 15 years, the carbon intensity was in obvious growth stage because of agricultural investment, growth rate was up to 120.32%;after 2007, neighborhood comparing growth of carbon emissions tended to be identical with carbon emissions intensity;(3) carbon emissions resulting from chemical fertilizer use was overwhelmingly dominant in the whole agriculture carbon emissions, which demonstrated the decline trend;the carbon emission deriving from power was ranked the second compared to chemical fertilizer use, and had increased by 22.1% in 1996 to 38.69% in 2010, carbon emissions of agricultural plastic films, pesticides and agricultural diesel were growing, but the proportion in the whole emissions was stable. Finally, based on the research results, the future agriculture emission reduction measures for emission reduction policy of Chongqing was put forward in order to provide reference to Chongqing low carbon agricultural development.
