减排对泰州市环境空气质量变化趋势的影响

目的]掌握泰州市减排措施实施后空气质量现状及其变化趋势。方法]对2013~2015年泰州市空气质量监测数据进行系统分析,研究减排对泰州市环境空气质量的影响。结果]受减排影响显著,空气质量有逐步好转的趋势。SO_2、PM_(10)、PM_(2.5)和CO年均浓度分别下降3.8%、12.9%、20.8%和30.2%,PM_(10)和PM_(2.5)下降幅度较大,NO_2和O_3年均浓度分别上升19.2%、19.3%。结论]能源结构变化、污染源综合整治是改善空气质量的关键。

Effects of Emission Reduction on the Change Trend of Environmental Air Quality in Taizhou City

Objective] To grasp the air quality status and change trend of Taizhou City after emission reduction.Method] The air quality monitoring data were analyzed during 2013-2015 in Taizhou City,effects of emission reduction on the change trend of environmental air quali-ty in taizhou city were researched. Result] The overall air quality of Taizhou was getting better gradually after emission reduction.he annual average concentrations of SO2 , PM10 , PM2.5 and CO dropped by 3.8%, 12.9%, 20.8%, 30.2% respectively.However, the concentrations of NO2 and O3 increased by 19.2% and 19.3% respectively.Conclusion] Energy structure change and comprehensive improvement of the pollution sources are the keys to improve air quality.
