基于夜间灯光数据的北部湾经济区能源消费碳排放量估算
Estimation of Carbon Emission from Energy Consumptionin Beibu Gulf Economic Zone Based on Nighttimer Light Data
摘要
Abstract
The Beibu Gulf Economic Zone serves as an important channel and open-up gateway in China,connecting multi-ple regions and opening to the outside world.Estimating and analyzing scientifically the spatial-temporal pattern of carbon emis-sions from energy consumption in Beibu Gulf Economic Zone,is of great significance to promote the high-quality development.Based on the long-term DMSP/OLS and NPP/VIIRS night light datasets,the carbon emissions of counties(districts)in Guangxi from 2005 to 2020 were estimated and corrected by the model to analyze the spatial-temporal characteristics of carbon emissions in Beibu Gulf Economic Zone from 2005 to 2020.The results have showed that:(1)The corrected nighttime light data is consis-tent,From 2005 to 2020,the TDN(total value of nighttime light)of Guangxi DMSP/OLS nighttime light images and the gross GDP of Guangxi were calculated for simulation,the goodness of fit of the estimated model was 0.975,meeting the requirement of accuracy.(2)There is a strong correlation between carbon emissions and TDN,the goodness of fit of the estimated model was 0.65,the overall average relative error of carbon emissions from energy consumption in Guangxi from 2005 to 2020 is 11.87%,showing reliable credibility.(3)The total carbon emissions from energy consumption in each county(region)have been showing increasing trend year by year,the spatial distribution has been characterized by"high in the central and coastal areas and low on both sides".The high carbon emissions have been concentrated in the urban of Nanning,Qinzhou,and Yulin,and low carbon emis-sions in the western and northeastern parts of the Beibu Gulf Economic Zone.关键词
