中国航空器碳排放测算与演化特征研究

Research on the Measurement and Evolution Characteristics of Aircraft Carbon Emissions in China

为进一步准确核算与深入分析民航碳排放,基于2007—2016年全国客货运航班运行数据对中国航空器起飞着陆(landing and take-off,LTO)阶段和爬升巡航下降(climb cruise and descent,CCD)阶段的碳排放量进行测算,并通过航线分段将航班CCD阶段碳排放分配至相关省份.最后分别从全国、区域,以及省域三个层次对民航碳排放核算结果及演化特征进行分析.结果表明:全国航空器碳排放总量呈快速、持续增长趋势;东部地区排放占全国排放总量比例最高,其次为中部、西部,但地区间排放差异有所缩小;CCD阶段碳排放是航空器运行过程中的主要排放;省域碳排放量不仅与省内航空业发达程度有关,还与省份地理位置、省域面积相关;多数省份被动排放对省份总碳排放量的贡献高于主动排放.

In order to further accurately calculate and deeply analyze the carbon emissions of civil aviation,the carbon emissions in the landing and take-off(LTO)phase and the climb cruise and descent(CCD)phase of Chinese aircrafts were calculated based on the operation data of national passenger and cargo flights from 2007 to 2016,and the carbon emissions in the CCD phase of flights were distributed to relevant provinces by route segments.Finally,the calculation results and evolution characteristics of the carbon emissions of civil aviation were analyzed from the national,regional and provincial levels respectively.The results show that the total amount of carbon emissions from aircrafts in China is increasing rapidly and continuously.The eastern region accounts for the highest proportion of the country’s total emissions,followed by the central and western regions,but the differences between regions have narrowed.Carbon emission in CCD stage is the main emission in aircraft operation.Provincial carbon emissions are not only related to the level of development of the aviation industry in the province,but also to the geographical location and area of the province.The contribution of passive emissions to total carbon emissions in most provinces is higher than that of active emissions.
