摘要
建筑业低碳化进程对城市的健康稳定发展具有重要意义。以淮海经济区中心城市为例,采用全生命周期方法测算建筑业碳排放量,应用Tapio脱钩模型分析建筑业不同来源碳排放与经济发展的关系。结果表明,徐州市建筑业碳排放以间接碳排放为主,历经增加-减少-平稳的演化过程,其中建筑运行造成的碳排放保持增加趋势;不同来源碳排放脱钩状态差异明显,碳排放总量与产值的脱钩关系先恶化后改善,建筑运行碳排放脱钩状态最不理想;能耗、技术、生活水平对碳排放总量减排效果较好,对建筑运行产生的间接碳排放减排作用有限。为实现建筑业的精准减排应重点关注间接碳排放,通过提高能源利用效率,加强科技创新减排以及宣传低碳生活理念等方式促进建筑业的低碳化发展。
The low-carbon process of construction industry is of great significance to the healthy and stable development of resource-based cities on the edge of provinces.Taking the central city of Huaihai Economic Zone as an example,the whole life cycle method was used to calculate the carbon emissions of the construction industry,and the Tapio decoupling model was used to analyze the relationship between carbon emissions from different sources of the construction industry and economic development.The results show that the carbon emission of construction industry in Xuzhou is mainly indirect carbon emission,which has experienced the evolution process of increasing-reducing-stable,and the carbon emission caused by construction operation keeps increasing trend.The decoupling status of carbon emissions from different sources was significantly different.The decoupling relationship between total carbon emissions and output value deteriorated first and then improved,while the carbon emissions from building operation was the least ideal.Energy consumption,technology and living standard have a good effect on the total carbon emission reduction,but have a limited effect on the carbon emission reduction of building operation.In order to achieve accurate emission reduction in the construction industry,it is necessary to focus on indirect carbon emissions,and promote the low-carbon development of the construction industry by improving energy efficiency,strengthening technological innovation and promoting the concept of low-carbon life.
