摘要
利用2012—2021年的NPP-VIIRS夜间灯光遥感影像作为主要数据源,收集2012—2021年广西北部湾城市群GDP和人口数据,统计得出广西北部湾城市群的夜间灯光亮度总值(DN值),将夜间灯光亮度总值分别与广西北部湾城市群对应年度的GDP增长以及人口数据进行回归分析,探究夜间灯光数据变化与社会经济发展的关系。结果表明:广西北部湾城市群社会经济数据与夜间灯光数据具有相关性,2012—2021年广西北部湾城市群的夜间灯光数据覆盖范围逐渐扩大,从2012年的592.75km^(2)增加到2021年的1513.5km^(2);该区域的社会经济发展呈上升趋势,且未来仍会持续快速上升。
By using the 2012—2021 NPP-VIIRS nighttime light remote sensing image as the main data source,the GDP and population data of the 2012—2021 Gulf of Tonkin urban agglomeration were collected.Based on the statistical results,the total evening light brightness(DN)of the Guangxi Gulf of Tonkin urban agglomeration was calculated.The DN of the Guangxi Gulf of Tonkin urban agglomeration was compared with the annual GDP growth and population data of Guangxi urban agglomerationto explore the relationship between the change of nighttime lighting data and the development of social economy.The results show that there is a correlation between the socio-economic data and the nighttime lighting data of the Gulf of Tonkin urban agglomerations in Guangxi.The coverage of the nighttime lighting data of the Gulf of Tonkin urban agglomerations in Guangxi from 2012—2021 has gradually expanded,from 592.75 km^(2) in 2012 to 1,513.5 km^(2) in 2021,the region'ssocio-economic development shows an upward trend and will continue to rise rapidly in the future.
