摘要/Abstract

摘要： 低碳循环发展的大背景下，三农碳汇生态产品的价值实现可助推三农低碳化发展并利农惠农。以生态脆弱区南疆四地州的户用沼气项目为研究对象，基于低碳循环的视角，利用小规模方法学AMS-Ⅲ.R和AMS-Ⅰ.C，综合测算温室气体的双重碳减排效益，估算其参与CERs项目后的经济效益，并进行项目碳减排成本的核算，最后就地区实际给出建议。结果表明：2020年南疆四地州户用沼气工程的总碳减排量为32.46×104 t/a，其中第一重碳减排量为0.96×104 t/a，第二重碳减排量为31.50×104 t/a，平均每户碳减排量为1.12 t/a；建池农牧民参与CERs项目的碳减排经济总收益可达3 385万元，参与CERs项目十年后的每户净现值为2 229.6元，内部收益率可达30%，动态投资回收期为3.16年；单位碳减排增量成本(ICER)为9.01元/t CO2当量，即1.42美元/t CO2当量。因此，其户用沼气CERs项目开发具有可行性，且开发潜力较大，加入碳交易市场实现其作为三农碳汇产品的价值对于地区生态恢复、减碳增收、巩固脱贫攻坚成果也有推动作用。

Abstract: Under the background of lowcarbon cycle development, the value realization of carbon sink ecological products of agriculture, the countryside and farmers can promote the lowcarbon development of agriculture, the countryside and farmers, and also benefit farmers. Taking the household biogas project in the four prefectures of southern Xinjiang in the ecologically fragile area as the research object, and based on the perspective of low-carbon cycle, the small-scale methodology AMS-Ⅲ.R and AMS-Ⅰ.C were adopted to comprehensively calculate the dual carbon emission reduction benefits of greenhouse gases, estimate the economic benefits after participating in the CERs project d, and calculate the carbon emission reduction costs of the project, and finally the actual suggestions aiming at the actual regional situation were put forward. The results showed that in 2020, the total carbon emission reduction of household biogas project in the four prefectures of southern Xinjiang was 32.46×104 t/a, of which the first carbon emission reduction was 0.96×104 t/a, the second carbon emission reduction was 31.50×104 t/a, and the average carbon emission reduction per household was 1.12 t/a, the total economic income of farmers and herders participating in the CERs project was 33.85 million yuan, and the net present value of each household after participating in the CERs project was 2 229.6 yuan, the internal rate of return could reach 30% and the dynamic payback period was 3.16 years, the incremental cost per unit of carbon reduction (ICER) was 9.01 yuan/ton CO2 equivalent, which was ＄1.42/ton CO2 equivalent. Therefore, the development of the household biogas CERs project is feasible and has great development potential, and participating the carbon trading market to realize the value as one type of carbon sink products of agriculture, the countryside and farmers will also promote regional ecological restoration, carbon reduction and income increase, and consolidate the achievements of poverty alleviation.
