China has met its annual target(年度目标) for pollution control in 2018, with more blue skies, cleaner waters and greener mountains.
Air quality in Beijing has seen strong improvements during the past six years. The city had 15 heavily polluted days in 2018, compared to 58 in 2013.
Blue sky days made up 79.3% of all days in 2018, up 1.3% from 2017, it said. Blue sky days refer to days when the average air quality index(指数) is lower than 100.
North China's Hebei Province will try hard to improve air quality further. The year 2018 had been the best year for cleaner air since air monitoring(监测) PM2.5 started in 2013.
Compared with 2013, when starting to monitor PM2.5, Hebei Province had 208 days with good air quality in 2018, up from 129 days. The number of days with heavy air pollution in Hebei decreased(减少) to 17, down from 80 days in 2013.
