摘  要:
为探讨上海郊区低碳农业经济的发展潜力与方向,参照IPCC提供的农业碳排系数和浙江省畜牧业和种植业的甲烷排放系数,考察了上海9个郊县近20年的农业碳排总量和结构特征。结果表明:2013年上海郊县的农业碳排总量排名前三的是浦东新区、崇明县和奉贤区,3个区县碳排之和占上海地区农业碳排总量的58.27%;上海郊区每万元农业产值排放二氧化碳当量,从1992年的2.5 t降至2013年0.95 t;1992—2013年上海农业碳排放的年平均几何增长率为9.1%,其中,能耗、农资、水稻灌溉和畜禽肠道发酵分别占农业碳排总量的54%、17%、18%和11%。以1992年为基期,计算了上海郊区1992—2013年农业碳排的脱钩弹性系数,结果显示农业碳排与农业经济发展之间基本呈弱脱钩关系。

摘  要:
This paper discussed the potential of carbon emission abatement in Shanghai agriculture to achieve low-carbon agricultural economy.Agro-emission coefficients suggested by IPCC,and modified methane coefficients from ranching and planting in Zhejiang Province,were used to calculate the total agro-emissions,while the agro-emissions from Pudong,Chongming,and Fengxian rank top three among nine suburbs,and account for 58%of total emissions;Emission intensity,measured in tons of CO_2-equivalent per 10,000 RMB of agricultural GDP,appeared to be decreasing continuously from 2.5 tons in 1992 to less than 0.95 tons in 2013;Geometric growth rate of Shanghai agro-emission was about 9.1%on average for the time period of 1992—2013;Agroemissions from energy consumption,inputs usage,irrigation and ranching,accounted for 54%,17%,18%and11%of total agro-emissions respectively.Decoupling elasticity was calculated using 1992 as a baseline,and elasticity ranges between-0.01 and 0.3 during 1992-2013,indicating that agro-emission had been weakly decoupled with agricultural economic development in Shanghai suburbs.
