中文摘要	有序推进中国南方石漠化地区农村低碳社区建设对石漠化综合治理、乡村振兴、精准扶贫等具有重要现实意义。以石漠化严重的贵州省4个不同等级石漠化县为研究区,系统梳理8种典型农村低碳社区模式,对比分析各种模式的适用范围及特点,基本符合现阶段社会经济状况与低碳社区的目标需求。运用投入-产出法评价典型低碳社区生态效益、经济效益,验证所提模型的有效性。结果表明:中国南方石漠化地区低碳社区建设难以形成统一模式与标准,低碳社区建设应因地制宜考虑产业结构、人口特征、乡村振兴和精准扶贫等,运用综合效益评估法来确定不同等级石漠化地区低碳社区适合发展方案。基于提高效益需要,从技术、发展、能源、制度、管理等5个视角,及中央政府、地方政府、电网公司、科研机构和社区农户5个层面设计的低碳社区综合效益提升途径,并提出8种典型低碳模式效益提升途径。
英文摘要	Green or sustainable design has gained good momentum as compact,resource-efficient,and affordable way in most communities.A low-carbon mode can also contribute to the comprehensive control of rocky desertification,rural revitalization,and targeted poverty alleviation in rural karst areas of southern China.In this study,four counties were taken as the study areas with different grades of karst rocky desertification in Guizhou Province.8 key approaches were then proposed to improve the benefits in the construction of typical low-carbon communities.It was found that:1) 8 kinds of typical patterns were found in the rural low-carbon mode,namely,a combination of courtyard solar lighting + coal heating cooking,solar water heater + coal heating cooker,solar water heater + household biogas cooking,solar water heater + small photovoltaic panel + electric heater heating + coal-type prickly ash roaster,solar water heater + rooftop photovoltaic + electric cooking,solar water heater + electric cooker + electric heater heating,solar water heater + household biogas + firewood saving stove,and solar water heater + fire pond + coal flue-cured tobacco.2) A mathematical model of benefit was designed for the low-carbon community to monetize the economic and environmental benefits.A field test was carried out to verify the feasibility and effectiveness of the low-carbon community model.The study areas were characterized by high environmental and low economic benefits on the whole.There were still some challenges on a unified standard for the specific construction of low-carbon community in study areas.It was also necessary to learn from the representative models in other regions,considering industrial structure,population characteristics,rural revitalization,and targeted poverty alleviation.The existing model of low-carbon community was basically in line with the local social and economic conditions,fully meeting the construction goal of the low-carbon community,although there was still large room to improve in each mechanism.3) 8 specific approaches to benefit improvement were as follows.Modle 1 was for the non-resource utilization of livestock manure and corn stalks,where to pilot the biological or natural gas,while moderately control the scale of live pigs and commercial cattle.Mode 2 was to improve the utilization rate of solar water heaters,where to pilot the fusion technology of solar and electric water heaters,and then introduce part of hot water into cooking energy.Mode 3 was aimed at a large number of farmers with large-scale pig breeding,where to pilot the integrated project of pig breeding - biogas - prickly ash,and further to develop the storage and purification of household biogas.Mode 4 was for a high demand of prickly ash coal resources,where to pilot electric prickly ash dryer.Model 5 was for the participation of the household,where to empower the household with management rights and economic rewards.Mode 6 was aimed at the non-resource utilization of discarded Zanthoxylum bungeanum branches,where to pilot the centralized collection and treatment.Mode 7 was aimed at indoor environmental quality,biogas leakage in the household,and non-resource utilization of rice straw,where to maintain the biogas digester,while pilot-test the curing treatment of straw and firewood.Mode 8 was for the utilization of coal and electricity in the flue-cured tobacco processing,where to pilot the heat conversion in a flue-cured tobacco room with a return air furnace and energy-saving facilities.
