Abstract
Rapid urbanization and economic developmentinevitably lead to light pollution, which has become a universalenvironmental issue. In order to reveal the change trend of lightpollution in China, Images from 1992 to 2012 were selectedfrom the Defense Meteorological Satellite Program OperationalLinescan System (DMSP/OLS) and systematically corrected toensure the consistency. Furthermore, we employed a linearregression trend method to measure China’s light pollutiontrend across national scales. We found that: (1) China’s lightpollution expanded significantly in provincial capital cities overthe past 21 years and hot-spots of light pollution were located inthe eastern coastal region. The Yangtze River Delta, Pearl RiverDelta, and Beijing-Tianjin-Hebei regions have formed lightpollution stretch areas.
