西北五省农业碳排放测算及碳减排潜力研究
A Study on Agricultural Carbon Emission and Carbon Emission Reduction Potential in Five Provinces in Northwest China
摘要
Abstract
The measurement of the potential of carbon emission reduction and potential scale is the prerequisite for the development of emission reduction policies and carbon trading market policies.In this study,based on 23 carbon sources from planting activities,animal husbandry,farmland soil and straw burning 23 kinds the agricultural carbon emission in the five provinces in Northwest China from 1995 to 2014 was calculated,and the temporal and spatial difference was analysed.On this basis,the environmental efficiency evaluation model(SBM model)was established to find out the optimal value of the objective function,and to calculate the potential index of the agricaltrual carbon emission induction the five provinces in Northwest China.The results showed:the average annual growth rates from 1995 to 2014 in Shaanxi,Gansu,Qinghai,Xinjiang,Ningxia agricultural carbon emissions were 1.71%,4.14%,-0.09%,3.77% and 4.06% respectively;and the average annual growth rates of the corresponding emission intensity were-9.08%,-5.57%,-9.94%,-6.57% and-7.14% respectively;the spatial difference was obvious,the order of carbon emission was Xinjiang>Shaanxi>Gansu>Ningxia>Qinghai,the carbon emission of Xinjiang was 4.61 times tha of Qinghai;the order of carbon emission intensity was Qinghai>Ningxia>Gansu>Xinjiang>Shaanxi,the emission tensity of Shaanxi was only 11/25 of that of Qinghai;in 20 years,the difference in the reduction potential of agricultural carbon emission was obvious among the five provinces in Northwest China.The carbon emission reduction potential of Qinghai was higher than that of the other four provinces,followed by Xinjiang,Ningxia,Gansu,Shaanxi,Shaanxi;the carbon emission reduction potential of Ningxia and Shaanxi showed a downward trend,Gansu,and that of Qinghai,Xinjiang showed an increasing trend.Finally,the five provinces in the northwest to develop appropriate agricultural carbon emission reduction policies,emission reduction mechanisms of cooperation and compensation mechanism to provide a reference.关键词
