摘要
为分析北京大兴国际机场海绵城市建设模式碳减排效果,对海绵设施在特枯水年、偏枯水年、平水年、偏丰水年、特丰水年的降雨条件下的碳源和碳汇进行了核算,分析了碳减排途径与效果。结果表明:相比传统建设模式,大兴国际机场海绵城市建设模式全年的碳减排量为795.6~1804.0 t二氧化碳排放当量,平均每年减少1221.2 t;不同水文特征年,大兴国际机场的碳排放量削减率为47.5%~58.7%,海绵城市建设模式的二氧化碳排放当量相对传统建设模式年均减少54.9%;在一定范围内碳排放当量随着降水量的增加而增加,降水量越多,机场海绵城市建设模式碳减排绝对减少量越大。
To analyze the carbon emission reduction effect of the sponge city construction model at Beijing Daxing International Airport,the carbon sources and sinks of sponge facilities under rainfall conditions in extra dry year,partial dry year,normal year,partial wet year,and extra wet year were calculated,and the pathways and effects of carbon emission reduction were analyzed.The results show that compared with the traditional construction mode,the carbon emission reduction of the sponge city construction model at Beijing Daxing International Airport for the whole year is 795.6~1804.0 t of carbon dioxide emission equivalent,with an average annual reduction of 1221.2 t.In different hydrological characteristics years,the carbon emission reduction rate of Daxing International Airport is 47.5%~58.7%,and the carbon dioxide emission equivalents of the sponge city construction model are reduced relative to airports of the traditional construction mode by an average of an annual reduction of 54.9%.The carbon dioxide emission equivalent increases with the increase of rainfall in a certain range,and the more precipitation,the greater the absolute reduction of carbon emission reduction of the sponge city construction model.
