| 中文摘要: |
| 农村供暖是北方地区碳排放的主要来源之一，本研究以《北方地区冬季清洁取暖规划（2017—2021年）》划定的“26+2”京津冀大气污染传输通道城市群农村地区为研究区，对利用农业废弃物进行生物质能清洁供暖的模式进行评估分析。基于“生物质能潜力核算-替代传统燃料资源量折算-污染物及碳减排效应估算”的研究框架，分别量化研究区内农作物秸秆和畜禽排泄物的生物质能潜力及减排效应。基于2019年统计面板数据，研究区农业废弃物的生物质能潜力较大，若合理充分开发利用，可替代约666万t标准煤或55亿m3天然气，实现减少污染物（SO2、NOx）排放量约21万t、降低CO2排放量约1 701万t的减排效应。本研究给出了研究区内28个地级市（直辖市）各类农作物秸秆及畜禽粪污生物质能利用潜力的空间分布及各省的清洁供暖减排效果，结果表明小麦和玉米资源化利用潜力最高；养殖业的生物质能利用潜力高于种植业，且以家禽养殖业为最高。该研究结果可为推动农村地区绿色低碳转型、探索从“农业废弃物”转为“农村供暖源”的发展路径提供有益参考。 |

| Rural heating is one of the main sources of carbon emissions in northern China. In this study, the“26+2”Beijing–Tianjin–Hebei air pollution transmission corridor urban agglomeration designated by the Winter Clean Heating Plan in the Northern Region（2017—2021） was used as the study area. Based on the framework of“estimating potential biomass energy-calculating alternative traditional fuel resources conversion-evaluating pollutant and carbon emission reduction effect”, the potential of biomass energy conversion and clean heating of crop straw and livestock and poultry excrement were quantitatively analyzed. Based on the panel data in 2019, the biomass energy potentials of crop straws and livestock and poultry emissions were considered. The biomass potential of these wastes indicate a reduction compared to the 6.66 million tons of standard coal or 5.5 billion m3 of natural gas, with emission reductions of approximately 0.21 million tons of pollutants（SO2, NOx）and 17.01 million tons of CO2 when fully exploited. In this study, the spatial distribution of biomass energy utilization potential of various crop straw and livestock manure in 28 prefecture-level cities（municipalities）in the study area and the effects of clean heating and emission reduction in each province were analyzed. Studies have shown that wheat and maize have the highest potential for resource utilization. The biomass energy utilization potential of the breeding industry was higher than that of planting industry, and the poultry breeding industry was the highest. The quantitative results could provide a useful reference for promoting the use of biomass energy to replace traditional fuels such as coal for clean heating in rural areas of“26 + 2”typical areas and exploring the development path from“agricultural waste”to“rural heating source” |
