摘　　要：为了获得市政道路低影响开发(LID)设施的低碳布置方案,定义了基于径流总量控制量的碳排放强度,其含义为全生命周期碳排放量与全生命周期径流总量控制量的比值。并以甘肃省天水市中心大道为研究对象,建立InfoWorks ICM模型,研究影响碳排放强度的主要因素。结果表明,当年降雨量一定时,较小面积比例的透水铺装或较大面积比例的雨水花园对碳排放量的控制效果较好;当LID设施面积比例一定时,年降雨量越小,对碳排放量的控制效果越好;正交试验显示,三种因素对碳排放强度的影响次序为透水铺装面积比例>雨水花园面积比例>年降雨量,当年降雨量比现状减少10%、透水铺装和雨水花园的面积比例均为10%时碳排放强度最小。从碳减排的角度考虑,优先布置最大面积比例的雨水花园,在年径流总量控制率未达到要求时再适当增加透水铺装的面积,此优化布置方案具有较好的碳减排效益。To acquire the low-carbon layout plan of municipal road low impact development(LID)facilities,the carbon emission intensity based on the total runoff control volume was defined,representing the ratio of the total carbon emissions throughout the whole life cycle to the total runoff control volume throughout the whole life cycle.The InfoWorks ICM model was constructed to investigate the main factors influencing carbon emission intensity in the Center Road of Tianshui City.When the annual rainfall remained constant,a relatively small proportion of permeable pavement or a relatively large proportion of rain garden had a superior control effect on carbon emissions.When the proportion of LID facilities area remained constant,the lower annual rainfall resulted in a better control effect on carbon emissions.The orthogonal test indicated that the influence of the three factors on carbon emission intensity in descending order was as follows:the proportion of permeable pavement area,the proportion of rain garden area and the annual rainfall.When the annual rainfall decreased by 10%and the proportions of both the permeable pavement and the rain garden area were 10%,the carbon emission intensity was the lowest.From the perspective of carbon emission reduction,prioritizing the layout of rain garden with the maximum area ratio,and appropriately increasing the area of permeable pavement when the volume capture ratio of annual runoff failed to meet the requirements,this optimal layout scheme had more favorable benefits in carbon emission reduction.
