摘要: 碳排放时空分布监测与评估是城市可持续发展的重点研究课题之一。面向长株潭城市群碳排放的时空分布和差异分析,本文基于NPP-VIIRS夜间灯光影像和不透水面数据,结合县级碳排放数据,构建长株潭城市群碳排放估算模型,并定量分析了长株潭城市群碳排放时空分布特征及变化趋势。结果表明:①不透水面、夜间灯光均值和总值数据能够反映长株潭城市群区域碳排放水平;②2013—2017年长株潭城市群碳排放具有聚集性,主要分布在长株潭城市群北部的中间区域,碳排放区域逐年扩大但强度减弱;③2013—2017年长株潭城市群碳排放变化趋势为中心区域呈现负增长,城市扩张的边缘区域承接了部分碳排放量。本文融合多源遥感数据对2013—2017年长株潭城市群县级碳排放进行估算与监测分析,揭示了长株潭城市群碳排放时空分布变化规律,可为该区域碳减排和区域可持续发展提供科学参考。

Abstract: The spatio-temporal distribution monitoring and evaluation of carbon emissions is one of the key research topics for sustainable urban development. For the analysis of the differences in the spatio-temporal distribution of carbon emissions in the Chang-Zhu-Tan urban agglomeration, this paper applies the NPP-VIIRS nighttime light images and impervious surface data, combined with county-level carbon emissions data to construct the carbon emission estimation model for the Chang-Zhu-Tan urban agglomeration, and analyzes the spatial and temporal distribution characteristics and changing trends of carbon emissions in this urban agglomeration. The results show that: ① The average and total value of nighttime lights and impervious surfaces data can better reflect the regional carbon emission level of the Chang-Zhu-Tan urban agglomeration.②From 2013 to 2017, the carbon emissions of the Chang-Zhu-Tan urban agglomeration were concentrated, mainly distributed in the middle area of the northern part. The carbon emissions areas expand year by year but the intensity weakened. ③ From 2013 to 2017, the changing trend of carbon emissions in the Chang-Zhu-Tan urban agglomeration was that the central area mainly has negative carbon emissions growth, while the peripheral areas have undertaken some carbon emissions. This study monitors the county-level carbon emissions of the Chang-Zhu-Tan urban agglomeration from 2013 to 2017 based on multi-source remote sensing data, and reveals the changes in the spatio-temporal distribution of carbon emissions, which can provide a scientific reference for carbon emission reduction and regional sustainable development.

Key words: carbon emissions, NPP-VIIRS nighttime light images, impervious surface data, spatio-temporal distribution features, Chang-Zhu-Tan urban agglomeration
