摘　　要：运用全生命周期评估方法分析了海绵城市建设中典型措施的碳足迹,考虑材料产出、运输、建设、运营、维修等主要环节,构建了典型海绵设施的碳排放核算体系。以我国第一批海绵城市建设试点河北省迁安市安顺家园小区为例,对典型海绵设施的全生命周期碳排放进行了核算,分析了碳排放的主要影响因素。结果表明:安顺家园小区海绵设施全生命周期内的直接碳排放量为33.060 t,主要来自降解污染物产生的碳排放;间接碳排放量为806.056 t,建造施工和拆卸阶段碳排放占比最大;碳汇量为2326.338 t,主要来自绿地固碳和雨水再利用;全生命周期30a内净碳排放量为-1487.220 t,预计该海绵改造方案有望在6.6 a实现碳中和;城市海绵建设对碳减排效果显著,可有效推进城市的绿色低碳发展,在未来海绵建设中应尽量选择低碳的建筑材料,同时采取合理的种植模式可以更好地发挥绿地的碳减排功效。The carbon footprint of typical measures in sponge city construction was analyzed using the whole life cycle assessment method,considering the main links of material production,transportation,construction,operation,and maintenance.A carbon emission accounting system for typical sponge facilities was constructed.Taking Anshun Jiayuan Community,Qian an City,as an example,the first batch of sponge city construction pilot projects in China,the whole life cycle carbon emissions of typical sponge facilities were calculated and the main influencing factors of carbon emissions were analyzed.The results show that the direct carbon emissions of sponge facilities throughout their whole lifecycle are 33.060 t,mainly from carbon emissions generated by the degradation of pollutants.The indirect carbon emissions are 806.056 t,with the highest proportion of carbon emissions during the construction and dismantling stages.The carbon sink amount is 2326.338 t,mainly from green space carbon sequestration and rainwater reuse.The net carbon emissions within the entire life cycle of 30 years are-1487.220 t,and it is expected that the sponge renovation plan will achieve carbon neutrality in 6.6a.The construction of urban sponge has a significant effect on carbon reduction,which can effectively promote the green and low-carbon development of cities.In future sponge construction,low-carbon building materials should be chosen as much as possible,and reasonable planting patterns should be adopted to better leverage the carbon reduction benefits of green spaces.
