摘要
[目的]科学测算土地整治工程过程碳排放,为实施低碳土地整治,实现碳达峰和碳中和目标提供科学参考。[方法]参照国际建筑领域的PAS2050规范,梳理土地整治工程施工过程碳排放机理。以碳排放系数法为基础,将土地整治工程预算定额转换为碳排放定额,并按照建筑工程概预算的计算思路,测算土地整治工程施工的总碳排放量。[结果]①土地整治工程碳排放定额是以《土地开发整理项目预算定额》中给定的相关预算定额为基础,运用碳排放系数法计算各个预算定额中所含一定量人力、材料、机械的碳排放量,继而将预算定额转变成碳排放定额,从而实现碳排放总量的计算;②依据PAS2050规范,土地整治工程碳排放的时空边界清晰,其对象边界、要素边界和碳源类型明确,并据此测算出案例项目碳排放总量为194225.95 kg。[结论]碳排放定额法在系统、全面、准确测算建筑施工过程碳排放方面具有较强应用前景,通过编制《土地开发整理项目碳排放定额》标准、开发“土地整治项目碳排放”软件和优化调整定额等方式,把碳排放定额法应用在土地整治实践之中,将有利于促进国土综合整治的节能减排。
[Objective]The carbon emissions in the process of land consolidation projects was scientifically measured,in order to provide support for the implementation of low-carbon land use and the realization of carbon peaking and carbon neutralization goals.[Methods]The carbon emission mechanism in the construction process of land consolidation project was analyzed according to specification of PAS2050 in the field of international architecture.Based on the carbon emission coefficient method,the budget quota of land consolidation project was converted into carbon emission quota,and the total carbon emission of the land consolidation project was measured and calculated according to the idea of construction project budget.[Results]①The carbon emission quota of land consolidation project was based on the relevant budget quota given in the budget quota of land development and consolidation project.The carbon emission coefficient method was used to calculate the carbon emission of a certain amount of manpower,materials and machinery contained in each budget quota,and then convert it into carbon emission quota,so as to finish the calculation of the total carbon emission.②According to specification of PAS2050,the space-time boundary,object boundary,element boundary and carbon source type of carbon emission of land consolidation project were clear.Based on these,the total carbon emission of the case would be calculated as 194225.95 kg.[Conclusion]The carbon emission quota method has a good application prospect in the systematica comprehensive and accurate calculation of carbon emission in the construction process.Through compiling the standard of carbon emission quota of land development and consolidation project,developing the software of carbon emission quota of land consolidation project and optimizing and adjusting quota,the carbon emission quota method is applied in land consolidation practice,which would be beneficial to promoting energy conservation and emission reduction of land consolidation.
