摘要
本研究对瑞昌市城区三个常年大气监测点的实验资料进行了系统的分析。分析结果表明,整个城区PM10的浓度夏季最低,冬季最高,其中冬季高出夏季1.88倍;城区春、秋、冬季PM10浓度峰值出现在傍晚19:00—20:00,次峰值出现在中午12:00—13:00,夏季的变化幅度不大,而PM10一年四季的谷值均出现在凌晨4点前后。本研究同时分析了瑞昌大气颗粒物污染的区域性特征的原因,并提出了相应的改进措施。
The massive experimental data of air pollution monitoring of Ruiehang are analyzed roundly and systematically. This study revealed the urban particulate matter level space - time distribution characteristics and changing regularity. And the changing regularity and diversity in different seasons, different monitoring areas concentration of particulate matter was proved. Furthermore the reasons of the urban particulate matter regional pollution in Ruiehang were analyzed, And appro- pilate improvement measures were proposed.
