基于CHAP数据集的2000-2020年中国PM2.5浓度变化趋势分析
Trend analysis of PM2.5 concentration in China from 2000 to 2020 based on CHAP dataset
摘要
Abstract
Based on the PM2.5 concentrations in the CHAP dataset and the national PM2.5 ground-level concentration monitoring data from 2015-2021,this study systematically analyses the trend of China's PM2.5 concentration changes from 2000 to 2020.The results show that the national PM2.5 concentration level peaked in 2010-2014 during the period 2000-2020,followed by a gradual decline.The high pollution value in spring mainly occurred in the Tarim Basin of Xinjiang,and the high pollution value in winter mainly occurred in the south of Hebei,the north of Henan and the west of Shandong.PM2.5 concentrations in all regions rose to a peak in 2013-2014 and then declined.The period when significant pollution occurred was from October to March,and the regional-type PM2.5 pollution levels peaked in 2012-2014,after which the pollution improved.关键词
