| 中文摘要: |
| 在“双碳”目标持续推进的背景下,高速公路作为典型的高能耗基础设施,其建设过程中的碳排放问题正日益受到广泛关注。高速公路全生命周期碳排放来源分为直接和间接碳排放。直接碳排放主要来源于材料生产和运输、机械施工和燃料燃烧等活动,核算方法包括实测法、质量平衡法、
投入产出法和碳排放因子法等。其中,碳排放因子法因其操作简便和标准化程度高而被广泛应用。间接碳排放则涉及土地利用变化所引起的土壤和植被变化以及高速公路营运的长期衍生影响。且不同材料和结构类型对碳排放影响存在显著差异。未来,生态修复技术和减排政策可被广泛应用
以降低碳排放。 |
| 英文摘要: |
| Amid the ongoing implementation of “Dual Carbon” goals, expressways, as representative highenergy-
consuming infrastructure, have attracted growing attention due to their significant carbon emissions,
particularly during the construction phase. Over the full life cycle of expressways, carbon emissions
can be broadly classified into direct and indirect sources. Direct emissions primarily originate from
the production and transportation of construction materials, the operation of machinery, and fuel combustion. Common accounting approaches include direct measurement, mass balance, input-output analysis,
and the emission factor method, among which the latter is most widely adopted due to its operational simplicity
and high standardization. Indirect emissions are mainly linked to land use changes, such as soil
disturbance and vegetation loss, as well as long-term operational impacts. Furthermore, the choice of
construction materials and structural designs significantly influences the overall carbon footprint. Looking
ahead, the large-scale application of ecological restoration techniques and the implementation of targeted emission
reduction policies are expected to play a key role in mitigating carbon emissions across the sector. |
