Abstract

Residential carbon emissions are an important component of anthropogenic carbon emissions. a significant increase in residential carbon emissions has become a reality under the global urbanization process. In this context, this paper built a feature combination value model based on NPP-VIIRS nighttime light remote sensing data, and divided urban-rural areas through breakpoint analysis method and reference comparison method. Then, explored the characteristics and differences of residential carbon emissions and per capita residential carbon emissions in nine different levels of cities in 2019 from the perspective of urban-rural areas. The results indicate that the residential carbon emissions and per capita residential carbon emissions shows the spatial distribution characteristics of first tier cities>second tier cities>third tier cities. Among them, the residential carbon emissions in Beijing, Guangzhou, Nanjing, Taiyuan show a distribution pattern of urban>urban-rural fringe>rural. The residential carbon emissions in Shijiazhuang, Wuxi, Xiangyang, Zunyi, Huai’an show a distribution pattern of rural>urban-rural fringe>urban. The per capita residential carbon emissions of urban areas are relatively low, while the per capita residential carbon emissions of rural areas are relatively high, show a distribution pattern of rural>urban-rural fringe >urban. The results can help the Chinese government balance the needs of urban-rural development in different levels of cities, so as to formulate targeted carbon emission reduction policies and achieve low-carbon goals.

中国城乡居民碳排放研究与分析
居民碳排放是人为碳排放的重要组成部分。在全球城市化进程中,居民碳排放大幅增加已成为现实。在此背景下,本文基于 NPP-VIIRS 夜间光照遥感数据建立了特征组合值模型,并通过断点分析法和参照比较法对城乡区域进行了划分。然后,从城乡区域角度探讨了2019年9个不同级别城市居民碳排放量和人均居民碳排放量的特征与差异。结果表明,居民碳排放量和人均居民碳排放量呈现出一线城市>二线城市>三线城市的空间分布特征。其中,北京、广州、南京、太原的居住碳排放呈现出城市>城乡边缘>农村的分布格局。石家庄、无锡、襄阳、遵义、淮安的居住碳排放量则呈现农村>城市-农村边缘>城市的分布格局。城市地区的人均居住碳排放量相对较低,而农村地区的人均居住碳排放量相对较高,呈现出农村>城市-农村边缘>城市的分布格局。研究结果有助于中国政府平衡不同级别城市的城乡发展需求,从而制定有针对性的碳减排政策,实现低碳目标。
