摘要:- 社區(qū)海綿化改造是海綿城市建設在流域-城市-社區(qū)層級中最基礎的環(huán)節(jié)，其碳排放的核算方法對于節(jié)能減排、實現(xiàn)碳中和具有重要的意義。以海綿城市建設過程為研究對象，針對其碳排放量底數(shù)不清、核算方法及減排途徑有待深入研究的現(xiàn)狀，以聯(lián)合國政府間氣候變化專門委員會（IPCC）指南為主要依據(jù)，基于生命周期評價法，構建了適用于居住社區(qū)海綿改造過程的碳排放核算方法，并以上海浦東新區(qū)濰坊街道社區(qū)為例，對海綿改造前后的碳排放量進行了具體核算，分析碳減排途徑與效果。結果表明，海綿改造中直接碳排放主要來自于海綿設施降解污染物產(chǎn)生的碳排放；間接碳排放包括材料生產(chǎn)碳排放、運輸碳排放和設備電耗能耗碳排放；碳匯則來自于海綿設施運行過程中的綠化固碳、雨水利用、徑流削減、雨水凈化、建筑節(jié)能等過程。全生命周期（30年）內(nèi)的直接碳排放量(以CO2計)為152.9 t，間接碳排放量為714.5 t，碳匯總量為2 070 t，預期在6.5年有望達到碳中和。綠化固碳是海綿改造過程中主要的碳匯來源，應盡可能充分利用現(xiàn)狀綠地，避免大改大建，以期在實現(xiàn)海綿設施控流減污的同時，綜合考慮碳排效應。
Abstract:- Community sponge reconstruction is the most basic part of sponge city construction at the level of river basin, city and community, and its carbon emission estimation method is of great significance for energy conservation and carbon neutralization. During the sponge city construction process, there are problems of unclear carbon emission base and lack of estimation method and emission reduction way. A carbon emission estimation method suitable for sponge reconstruction of residential communities was established based on the guidelines of the intergovernmental panel on climate change (IPCC) and the life cycle assessment (LCA) method. The carbon emission before and after sponge reconstruction was calculated in Weifang Street Community, Pudong New Area, Shanghai, and the carbon emission reduction effect was analyzed. The direct carbon emission during the sponge reconstruction city was mainly from the degradation process of pollutants in the sponge facilities. The indirect carbon emissions included the material production, transportation and power consumption of the equipments. The carbon sink was from greening carbon sequestration, rainwater utilization, runoff reduction, rainwater purification, building energy conservation and other processes during the operation of sponge facilities. In the whole life cycle (30 years), the direct carbon emission was 152.9 tons, the indirect carbon emission was 714.5 tons, and the total carbon sink was 2 070 tons. It was expected to reach the carbon neutralization in 6.5 years. The greening carbon sequestration was the main source of carbon sink in the process of sponge reconstruction. Therefore, it is necessary to make full use of the current green space as far as possible to avoid large-scale reconstruction, so as to realize the flow control and pollution reduction of the sponge facilities and comprehensively consider the carbon emission effect.
