内蒙古寒旱地区公路施工阶段碳排放因子测算研究

Calculation of the carbon emission factors during highway constructions in cold and dry region of Inner Mongolia

碳排放因子是计算公路工程施工阶段碳排放的数据基础,但碳排放因子因时间、技术和地区等表现出巨大差异.为系统地、准确地对公路施工阶段的碳排放进行量化,要使用公路项目所在地的碳排放因子数据库.根据内蒙古寒旱地区的气候和公路施工工艺等特点,对现有数据库中的碳排放因子进行修正,建立了适用于内蒙古寒旱地区公路项目的碳排放因子数据库.

Carbon emission factor is the data basis for calculating the carbon emission in the construction stage of highway engineering,but the carbon emission factors show great differences due to production technology and region.In order to quantify the carbon emission in the highway construction stage systematically and accurately,the carbon emission factors database of the highway project location should be used.According to the characteristics of climate and highway construction technology in the cold and dry region of Inner Mongolia,the carbon emission factors in the existing database were modified,and a carbon emission factors database suitable for highway projects in the cold and dry region of Inner Mongolia was established.
