摘要
针对中国秸秆焚烧多发的东三省地区,利用2015—2017年秋季卫星火点监测数据和空气质量监测数据对东三省秸秆焚烧的空气污染效应展开研究。研究显示:(1)2015—2017年秋季东三省秸秆焚烧火点数逐年增多,火点聚集区逐年向西扩展;(2)2015—2017年秋季秸秆焚烧期间东三省的气团主要对东三省内部产生影响,秸秆焚烧对空气质量指数(AQI)的影响主要分成3个阶段(平缓阶段、上升阶段和下降阶段),说明秸秆焚烧对AQI有显著影响;(3)秸秆焚烧对PM_(2.5)、PM_(10)、NO_(2)、CO和SO_(2)有显著影响,而O_(3)由于来源不同,不受影响。
Straw burning was occured frequently in three provinces of northeast China.Therefore,a study on the influence of straw burning in autumn on air pollution in three provinces of northeast China from 2015 to 2017 was conducted by using the satellite monitored straw burning points and air quality observation data.Results showed that:(1)straw burning points in the three provinces of northeast China tended to be increasing from 2015 to 2017,and the straw burning points high-density area gradually expanded westward.(2)The air mass in the three provinces of northeast China affected the local area mainly.The influence of straw burning on AQI was divided into 3 periods of stable period,increasing period and decreasing period,indicating a significant effect.(3).Straw burning had significant influence on PM_(2.5),PM_(10),NO_(2),CO and SO_(2) except O_(3),because the source of O_(3) was different.
