Urban Air Quality Evaluation Based on Dual Weight Element Extension Model
In order to objectively and accurately evaluate air quality,it is very important to select a reasonable weighting method and evaluation model.In this paper,SO2,NO2,CO,O3,PM10 and PM2.5 are selected as evaluation factors,pollutant concentration and toxicity are weighted superimposed,and a dual-weight weight element extension air quality evaluation model is established by combining the matter element extension principle.The air quality of Xi'an city in 2023 was evaluated.The results show that the dual weight element extension evaluation model is a scientific and effective air quality evaluation method,which can provide reference for government departments to control pollution.
