基于农业投入的重庆农业碳排放时序特征及减排措施研究
Research on Temporal Characteristics and Reduction Policy Based on Input in Chongqing Municipality
摘要
Abstract
Agriculture has become one of the main sources of carbon emissions in the world, which has attrac ted worldwide concern. Based on the input of chemical fertilizers, pesticides, agricultural plastic films, pow- er consumption and diesel, carbon emissions of Chongqing in recentl5 years from 1996 to 2010 was esti- mated. 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 compa- ring 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 emis- sions, 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 emis- sions 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.关键词
