摘要
基于全生命周期法,构建了一种适用于城区范围的海绵城市雨水系统碳排放量化方法,并以松原市某片区为例,对4种海绵城市规划方案进行碳排放计算和比较,分析其碳减排效果并提出减排建议。结果表明,传统城市雨水系统碳排放高的主要原因是缺乏源头雨水渗蓄;雨水管网建设是系统碳排放的主要来源;与传统规划方案相比,4种海绵城市规划方案可使系统碳排放减少3. 5%～51. 7%。
Based on the Life Cycle Assessment method,an urban scale model of carbon emission for sponge city stormwater system was developed.Taking the case of a district in Songyuan City,carbon emissions of four sponge city planning schemes were analyzed and compared,and some suggestions for emissions reduction were proposed.The results show that the important reason for the high carbon emission of traditional urban stormwater system is the lack of rainwater detention and infiltration;the construction of storm sewer network is the main source of carbon emissions in the system;compared with the traditional planning scheme,the four sponge urban planning schemes reduce the carbon emissions by 3.5%~51.7%.
