大气环境质量底线中的污染传输影响分析--以四川省典型城市为例

Analysis on the Influence of Air Pollution Transport in the Bottom Line of Atmospheric Environmental Quality--A Case Study of Typical Cities in Sichuan

为了研究四川地区大气污染的传输影响,本文利用LPDM模型和WRF-CMAQ模型对四川地区颗粒物和臭氧的输送进行了研究。利用WRF-CMAQ模型诊断出2015年是2013-2017年间气象条件最好的一年,2017年为最差的一年。成都地区的颗粒物污染多是本地生成,臭氧污染多为输入性污染。

In order to understand the transmission effect of air pollution in Sichuan,the transport patterns of particulate matter and ozone in Sichuan area was studied by LPDM model and WRF-CMAQ model. It was diagnosed by the WRF-CMAQ model that 2015 was the best year for atmospheric conditions in 2013-2017 and the worst year was 2017. Particulate pollution in Chengdu area is mostly generated by local sources,and ozone pollution is mostly by tranpotation from other areas.
