广东省农业生产能源消费碳排放分析及减排对策

Analysis on Carbon Emissions from Energy Consumption in Agricultural and Reduction Measures in Guangdong Province

[目的]研究广东省农业生产能源消费CO2排放量,并提出可行的减排对策。[方法]基于《中国能源统计年鉴》和《广东统计年鉴》提供的农业终端能源消费数据,采用IPCC推荐的碳排放计算方法,估算了2000～2009年广东省农业生产终端能源消费CO2排放量,并提出了相应的减排措施。[结果]随着农业产值和能源消费的快速增长,2000～2009年广东农业终端能源消费CO2排放总量总体呈不断上升的趋势,从2000年的423.63万t碳增加到2009年的605.99万t碳,年均增长率4.1%;而农业终端能源消费的碳排放强度则不断下降,从2000年的0.424 t碳/万元下降至2009年的0.301t碳/万元,年均下降率为3.7%。农业产值增长、能源利用效率提高、农业能源消费结构高碳化等是农业终端能源消费CO2排放变化的主要影响因素。通过大力开发利用农村可再生能源,开发推广先进的能源利用技术,加快推进农业机械的节能,建立健全农业生产能源消费碳排放的宏观调控机制等措施,可以减少农业生产能源消费的二氧化碳排放量。[结论]该研究为广东省农业生产能源消费碳减排政策的制定提供了依据。

[Objective] The aim was to study CO2 emissions from energy consumption in agricultural production in Guangdong Province and put forward feasible reduction measures.[Method] Based on the data from China Energy Statistical Yearbook and Guangdong Statistical Yearbook,CO2 emissions from agricultural energy use in Guangdong Province from 2000 to 2009 was estimated by using the formula of carbon emissions recommended by Intergovernmental Panel on Climate Change（IPCC）,and corresponding reduction measures were put forward.[Result] With the rapid increase of agricultural output and energy consumption,CO2 emissions during energy consumption of agricultural production in Guangdong Province showed increasing trend from 2000 to 2009,that is to say,increasing from 423.63×104 t C million tons in 2000 to 605.99×104 t C in 2009,with annual growth rate of 4.1%.Meanwhile,carbon emissions intensity during energy consumption in agriculture went down in recent ten years,in other words,decreasing from 0.424 t C/×104 yuan in 2000 to 0.301 t C/×104 yuan in 2009,and its annual decreasing rate was 3.7%.The variation of CO2 emissions during energy consumption of agricultural production mainly resulted from the increase of agricultural output,improvement of energy utilization efficiency,high carbonization of agricultural energy consumption structure and so forth.Therefore,in order to reduce CO2 emissions during energy consumption of agricultural production,it is necessary to vigorously develop rural renewable energy,develop and popularize advanced technology for energy utilization,advancing of energy conservation of agricultural machines,establish and improve the macroeconomic control mechanism for carbon emissions during the energy consumption in agricultural production in the further.[Conclusion] The study could provide references for the making of policy about reducing carbon emissions from agricultural energy consumption production in Guangdong Province.
