摘要
面对中国“碳达峰”和“碳中和”的国家战略,以及新乡村建设的推进,乡村建筑业的碳排放控制尤为关键。本研究采用经济投入产出分析与Kaya恒等式,深入探讨了乡村建筑业碳排放的影响因素,并提出了改进措施。通过建立碳足迹模型,研究团队对建筑业的直接和隐含二氧化碳排放进行了定量分析。分析结果表明,能耗是乡村建筑直接碳排放的主要来源,而隐含碳排放则与相关产业活动紧密相关。能源结构的优化对减少碳排放至关重要。因此,本文建议采取一系列技术升级策略,包括优化建筑设计、减少材料使用、提升建筑物能效及施工废弃物的回收利用,以实现乡村建筑业的低碳转型。这些策略不仅为降低乡村碳排放提供了理论支持,也为实践中的应用指明了方向。
In the face of China's national strategy for carbon peaking and carbon neutrality,as well as the advancement of new rural construction,carbon emission control in the rural construction industry is particularly crucial.This study adopted economic input-output analysis and the Kaya identity to discuss the influencing factors of carbon emissions in the rural construction industry in an in-depth way,and proposed improvement measures.By establishing a carbon footprint model,the research team conducted a quantitative analysis of both direct and embodied CO,emissions from the construction industry.The analysis revealed that energy consumption is the primary source of direct carbon emissions from rural construction,while embodied carbon emissions are closely linked to related industrial activities.Optimizing the energy mix is essential to reducing carbon emissions.Therefore,this paper proposed a series of technological upgrading strategies,including optimizing building design,reducing material use,improving building energy efficiency,and recycling construction waste,to achieve a low-carbon transformation of the rural construction industry.These strategies provide not only theoretical support for reducing rural carbon emissions but also guidance for practical application.
