摘　　要：目前在建筑碳排放的计算模型中,只考虑了建筑的碳排放和绿化环境引起的碳汇,忽略了因建筑材料可吸收和固定CO_(2)而产生的建筑碳汇,对于建筑碳排放的计算存在盲区和误差。因此本文以建筑材料的固碳机理为基础,通过分析现有建筑碳汇的相关计算方法和数学模型,推导出了分别适用于混凝土和生物质两类具有碳汇功能的建筑固碳量的计算简化模型。优化后的模型可为完善现有的建筑碳排放计算模型提供科学依据,并有助于指导建筑师在设计之初选用高碳汇材料以减少建筑材料引起的“净”碳排放量。At present, in the calculation model of building carbon emissions, only the carbon emissions of building and the carbon sinks caused by greening the environment are considered, while the building carbon sinks generated by building materials capable of absorbing and fixing carbon dioxide are ignored,and there is a blind spot and error for the calculation of building carbon emission. Therefore, based on the carbon sequestration mechanism of building materials, this paper analyses the relevant calculation methods and mathematical models of existing building carbon sinks, and derives a simplified model for calculating building carbon sinks with carbon sink functions for concrete and biomass respectively.The optimised model can provide a scientific basis for improving the existing building carbon emission calculation model, which can help guide architects to select high carbon sink materials at the beginning of the design process and reduce the "net" carbon emissions caused by building materials.
