今年上半年，中国环境空气质量总体持续改善，这是中国生态环境部新闻发言人、宣传教育司司长裴晓菲在北京新闻发布会上透露的信息。根据裴晓菲的介绍，全国339个地级及以上城市的环境空气质量在上半年取得了显著进步，主要污染物指标呈现出“四降一升一平”的态势，即PM2.5、PM10、SO2、NO2平均浓度同比下降，O3平均浓度同比上升，CO平均浓度持平。
在空气优良天数比例方面，全国339个城市平均达到了82.8%，比去年同期上升了1.4个百分点，重度及以上污染天数比例同比下降了1.1个百分点。重点区域中，汾渭平原13个城市PM2.5平均浓度同比下降了8.3%，优良天数比例上升了1.6个百分点，重度及以上污染天数比例下降了4.0个百分点。京津冀及周边地区和长三角地区的PM2.5平均浓度同比虽有不同程度的上升，但优良天数比例和重度及以上污染天数比例都有所下降。
生态环境部还通报了2024年6月和1—6月全国环境空气质量状况，其中168个重点城市中，空气质量排名前20位的城市多为西南地区和沿海城市，而空气质量排名后20位的城市则集中在河南、河北等工业较为发达的地区。PM2.5浓度排名前20位的城市中，沿海城市和西南地区的城市也占据多数，而PM2.5浓度排名后20位的城市则以河南、河北等地的城市为主。
这一系列的改善表明中国政府在环境保护方面取得了积极成效，同时也提醒地方政府和相关部门要继续努力，确保空气质量持续改善，为人民群众创造更加宜居的环境。

News Title: “China’s Environmental Quality Continuously Improves in First Half of the Year”
Keywords: Improvement, Air Quality, Continuous

In the first half of this year, China’s overall environmental air quality has continued to improve, a fact revealed by Xiaofei Pei, the spokesperson for the Ministry of Ecology and Environment and the director of its Publicity and Education Bureau, during a news conference in Beijing. According to Pei’s introduction, there has been significant progress in the environmental air quality of the 339 cities at or above the prefecture level across the country in the first half of the year. Major pollutant indicators show a trend of “four decreases and one increase and one unchanged,” meaning a decrease in the average concentrations of PM2.5, PM10, SO2, and NO2, an increase in the average concentration of O3, and a constant average concentration of CO.
In terms of the proportion of days with good air quality, the average for the 339 cities reached 82.8%, an increase of 1.4 percentage points over the same period last year. The proportion of days with heavy or more pollution decreased by 1.1 percentage points year-on-year. In key regions, the average concentration of PM2.5 in the 13 cities of the Fenwei Plain decreased by 8.3%, the proportion of days with good air quality increased by 1.6 percentage points, and the proportion of days with heavy or more pollution decreased by 4.0 percentage points. Although the average concentration of PM2.5 in the Beijing-Tianjin-Hebei region and the Yangtze River Delta area increased year-on-year, the proportion of days with good air quality and the proportion of days with heavy or more pollution both decreased.
The Ministry of Ecology and Environment also reported on the national environmental air quality conditions for June 2024 and the first six months of the year. Among the 168 key cities, the top 20 cities in terms of air quality are mostly from the southwest region and coastal cities, while the bottom 20 cities are concentrated in areas with more industrial development, such as Henan and Hebei provinces. Among the top 20 cities with the highest PM2.5 concentrations, cities from the coastal regions and the southwest also account for the majority, while the cities with the bottom 20 PM2.5 concentration rankings are mainly from Henan, Hebei, and other areas.
These improvements indicate that the Chinese government has achieved positive results in environmental protection. They also remind local governments and relevant departments to continue their efforts to ensure continuous improvements in air quality and to create a more livable environment for the people.
