夜间灯光较为客观地反映了人类社会的生产和生活活动状况。照明数据用于通过比较明亮区和暗区来研究某个地区的发展和人口活动。照明的强弱与社会经济因素之间存在正相关关系。本文利用DMSP/OLS的2009年和VIIRS/DNB的2018年夜间灯光数据进行对比，查看研究区的灯光数据变化，从而估计人口变化和经济发展状态。

Nighttime lights objectively reflect the status of production and living activities in human society. Lighting data is used to study the development and population activities of a region by comparing bright and dark areas. There is a positive correlation between the intensity of lighting and socioeconomic factors. This paper uses nighttime light data from DMSP/OLS (2009) and VIIRS/DNB (2018) for comparison, examines changes in light data in the study area, and thereby estimates population changes and economic development status.
