基于双权重模糊综合评判的南京空气质量评价
Application of fuzzy comprehensive assessment grounded on double weighing factors in assessment of Nanjing air quality
摘要
Abstract
In order to effectively evaluate the degree of air pollution,a double factor fuzzy comprehensive assessment method,taking toxicity into consideration,based on traditional single factor method was proposed and applied for air quality assessment of Nanjing.Also,the assessment result was compared with the result of single weighing factor method.Both the assessment results from the two methods indicate that the main pollutants are PM2.5,PM10 and NO2.The Nanjing air quality has been improved year by year since 2013.The air quality of summer and fall is better than winter and spring.The weight of PM2.5counted by two weighing factors is twice bigger than single weighing factor.The weight of PM2.5 and PM10 takes up more than 60％ of the total,and is significantly higher than other pollution factors due to strong toxicity of particulates.Compared with single factor method,two weighing factor method is a more objective assessment method because extent of jury of different pol lutants is taken into consideration.关键词
