注：1. 从2016年起根据《环境空气质量标准》(GB3095-2012)等有关环境空气质量评价要求： |  |  |  |  |  |
1) 市区二氧化硫年日平均值、市区二氧化氮年日平均值、市区可吸入颗粒平均浓度、市区PM2.5平均浓度4个指标分别修改为二氧化硫平均浓度、二氧化氮平均浓度、可吸入颗粒物平均浓度、PM
2.5平均浓度；且单位毫克/立方米均修改为微克/立方米。 |  |  |  |  |  |

Note: I. According to the Environmental Air quality Standards (GB3095-2012) and other relevant environmental air quality evaluation requirements: |  |  |
I) The annual daily average of sulfur dioxide in urban area,the annual daily average of nitrogen dioxide in urban area,the average concentration of inhalable particles in urban area and the average concentration of
PM2.5 in urban area were revised to mean concentration of sulfur dioxide and nitrogen dioxide, respectively. The mean concentration of inhalable particulate matter and PM2.5； And unit milligram/cubic
meter is revised to microgram /cubic meter. |  |  |  |  |  |  |
II) The number of good days of ambient air quality has been revised to the number of days when the quality of ambient air has reached the standard. |  |  |
III) The ambient air quality rate is modified to the ambient air quality standard rate. |  |  |  |  |  |
II. The data of Forest Fires in 2018 includes all the forest fires. |  |  |  |  |  |
III. The data of Waste Water ,Waste Gas and Solid Wastes in 2019 is from quick statistics data. |  |  |  |  |  |
IV. The statistical coverage of Forest Fires has included all kinds of forest fires since 2018. |  |  |  |  |  |
V. The per capita arable land area and urban construction land area are temporarily missing because the Third National Land Survey has not been fully completed. |  |
