摘要
在城市化进程加快导致温室气体排放过载的背景下,低碳可持续发展成为各行业关注的焦点。为探究LID措施对雨洪系统碳排放产生的影响,以铜陵枞阳县为例,搭建SWMM模型进行雨水管网的碳排放量核算。模型中设置的LID设施主要为雨水花园及透水铺装,占城区汇水面积的比例分别约为19.7%和0.7%,总计约20.4%。结果表明:通过在枞阳县城区增设一定规模的LID设施,与原始管网相比可有效减少23.3%的地表径流,拦截66.8%的初期雨水,使城市排水设施在运行过程中较未使用LID设施前所产生的碳排放量削减62.7%。
In the context of the acceleration of urbanization leading to the overload of greenhouse gas emissions,low-carbon and sustainable development have been the focus of various industries.In order to explore the impact of the carbon emissions of the stormwater system caused by LID,a SWMM model was built to calculate the carbon emissions of the stormwater pipe network in Tongling Zongyang County.The rain gardens and permeable paving were mainly settings of the LID facilities in the model,accounting for about 19.7% and 0.7% of the urban catchment area,respectively,total about 20.4%.Compared with the LID facilities unused,the results demonstrated that the surface runoff can be effectively reduced by 23.3%,66.8% of the initial rainwater can be intercepted,and the carbon emissions under the operation of urban drainage facilities can be declined by 62.7% by scaling up the LID facilities.
