摘　　要：在全球共同应对碳排放问题背景下,国内景观行业碳排放计算缺乏明确标准,并存在着借鉴他专业计算模型导致碳排放估算结果差异化问题。为此,本文通过考察梳理《建筑碳排放计算标准》(GB/T51366-2019)及相关研究,将景观全生命周期边界明确为材料生产、植物起挖、材料及植物运输、景观施工、植物种植、景观运行、景观养护管理及更新拆除8个阶段;对各阶段碳排放计算因子间的共性与差异性进行对比分析,导出景观全生命周期各阶段的碳排放计算因子;利用德尔菲调查法加以验证,最终确定景观全生命周期碳排放的计算模型,以期为国内景观全生命周期碳排放估算的相关研究提供参考。In the context of the global response to carbon emissions,There is a relative lack of clear standards for the calculation of carbon emissions in the landscape industry in China.There is a problem of differentiation of carbon emission estimation results caused by reference to the professional calculation model.To this end,the paper examined and sorted out the carbon emission calculation model of the"Building Carbon Emission Calculation Standard"(GB/T 51366-2019)and related studies.The whole life cycle assessment boundary of landscape is defined as eight phases:material extraction,plant digging,material and plant transportation,landscape construction,plant planting,landscape operation,landscape maintenance management and renewal and demolition.By analyzing and comparing the commonalities and differences among carbon emission calculation factors at different phases.The carbon emission calculation factors of each phase of landscape life cycle assessment were preliminarily derived and tested with the Delphi method.Finally,the carbon emission estimation method of landscape life cycle assessment and the carbon emission calculation model of each phase were established.To provide a reference for the research on the estimation of carbon emissions in the whole life cycle of landscape in China.
