公路系统固碳现状与潜力

——基于碳汇理论的公路两侧碳汇林带建设

摘  要：目前，随着公路建设的发展和交通体系的完善，不断增加的机动车的碳排放对环境造成极大的影响。该文通过对公路交通小系统的碳排放和吸收分析，认为可通过公路两侧种植碳汇林来达到排放与吸收的平衡。

Abstract： At present， with the development of highway construction and the improvement of transportation systems， the increasing carbon emissions of motor vehicles have had a great impact on the environment. Based on the analysis of carbon emissions and absorption in small highway transportation systems， this paper believes that the balance between emissions and absorption can be achieved by planting carbon sink forests on both sides of the highway.

Keywords： highway; carbon emission; plant absorption; neutral carbon sink; cross-section design
