基于双权重物元可拓模型的城市空气质量评价研究

Urban Air Quality Evaluation Based on Dual Weight Element Extension Model

为了客观准确地评价空气质量,选取合理的赋权方法和评价模型十分重要。文章选取SO_(2)、NO_(2)、CO、O_(3)、PM_(10)、PM_(2.5)作为评价因子,将污染物超标倍数与毒性指数加权叠加,结合物元可拓原理,建立双权重物元可拓空气质量评价模型,对2023年西安市空气质量进行评价。结果表明,双权重物元可拓评价模型是一种科学有效的空气质量评价方法,可为政府部门污染治理提供借鉴和参考。

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,SO_(2),NO_(2),CO,O_(3),PM_(10) and PM_(2.5) 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 scientif ic and effective air quality evaluation method,which can provide reference for government departments to control pollution.
