摘要

划分不同尺度的减排区对黄河流域的生态保护和高质量发展具有重要意义。基于遥感数据和光碳转换模型,测算了黄河流域省、市、县三级碳足迹。利用时空演化分析方法,比较了三个空间尺度碳足迹的时空演化临界路径,并将其划分为不同的区域。结论如下(1)碳足迹逐年增加。三种尺度的碳足迹空间分布不仅一致,而且存在差异。县域尺度的碳足迹研究更有利于时空演变的总结和详细减排方案的制定。(2)4 个省、48 个市、373 个县被划定为 "核心保护区";3 个省、29 个市、177 个县被划定为 "严格治理区";1 个省、12 个市、47 个县被划定为 "重点限制区";4 个市、39 个县被划定为 "警戒扩散区"。(3)县域范围内高碳足迹单位的集聚扩张趋势和溢出效应更加明显。县域碳足迹的路径锁定特征进一步增强,将增加治理难度。县域尺度碳足迹的有效治理迫在眉睫。这些结果为黄河流域多尺度碳排放控制和分区政策制定提供了科学依据。

Multiscale spatiotemporal evolution and zoning of energy consumption carbon footprint in the Yellow River Basin

Classifying emission reduction zones on different scales has important implications for the ecological protection and high-quality development of the Yellow River Basin. Based on remote sensing data and a light-carbon conversion model, carbon footprints at provincial, municipal, and county scales in the Yellow River Basin are measured. The spatiotemporal evolution critical paths of carbon footprints at the three spatial scales are compared and classified into different zones using spatiotemporal evolution analysis methods. The conclusions are as follows: (1) The carbon footprint increased over the years. The spatial distributions of carbon footprints at the three scales are not only consistent but also different. The study of carbon footprints at the county scale is more conducive to the summary of the spatiotemporal evolution and the formulation of detailed emission reduction schemes. (2) Four provinces, 48 cities, and 373 counties are designated as a “core protected zone”; three provinces, 29 cities, and 177 counties are designated as a “strictly governed zone”; one province, 12 cities, and 47 counties are designated as a “key restricted zone”; four cities and 39 counties are designated as an “alert diffusion zone.” (3) The agglomeration expansion trend and the spillover effect of high-carbon footprint units at the county scale are more obvious. Further enhancement of the path-locking characteristics of the carbon footprints of counties will make governance more difficult. Effective governance of carbon footprint at the county scale is of urgent concern. These results provide scientific evidence for multiscale carbon emission control and zoning policy formulation in the Yellow River Basin.

期刊介绍: Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
