随着社会和经济的高速发展,能源消耗量快速增加,随之而来的污染问题也日益加剧.目前的研究主要集中于单一城市或长三角、珠三角和京津冀等中国三大经济圈的道路交通节能减排,缺乏对东南沿海经济圈的相关研究.粤闽浙三省位于我国东南沿海经济发展的核心地带,在其经济发展的同时不可避免地带来了能耗及排放问题.基于长期能源替代规划系统模型,构建了2015~2035年粤闽浙沿海重点城市道路交通基准情景(BAU)以及现有政策情景(EPS)和改进政策情景(MPS),其中,EPS和MPS均设置了车辆结构优化情景(VSO)、提高燃油经济性情景(IFE)和年均行驶里程减少情景(RDM).基于情景模拟,评估在各项政策和措施的作用下,粤闽浙沿海重点城市的道路交通节能减排潜力.结果表明,在一级情景中,改进政策情景对于节约能耗、碳减排以及污染物减排效果最好,相比于基准情景2035年其节能力度达75%,且对CO_(2)、CO、NO_(x)、PM_(2.5)和SO_(2)的排放削减力度分别达68%、59%、66%、70%和64%;在二级情景中,提升燃油经济性的改进情景对于节约能耗(削减30%)效果显著;车辆结构调整的改进情景(削减36%、30%、36%、26%和40%)和年均行驶里程减少的改进情景(削减37%、37%、36%、37%和36%)对于CO_(2)、CO、NO_(x)、PM_(2.5)和SO_(2)减排效果显著.
