基于AHP法的石河子发电厂周边空气质量评价

Air Quality Evaluation of Shihezi City Based on Fuzzy-Analytic Hierarchy Process

空气质量是评判环境健康的重要指标,如何对空气质量进行客观、综合的评价是关键问题。针对石河子环境质量状况,以石河子市阳光双语学校、石河子南区热电厂为实验区域,采集二氧化碳、一氧化碳、PM2.5浓度数据,采用格拉布斯准则、皮尔逊积矩系数完成数据筛选与相关性分析,建立实测数据与官网数据数学转换模型,利用基于模糊学理论的层次分析法(AHP,Analytic Hierarchy?Process)完成空气质量等级评价模型的构建。实验结果表明:系统采集的数据与官网数据相关性大于0.97,产生的模型精度较高,达到了准确性为93.3%的环境等级评价结果,验证了评价模型的可靠性和有效性。

Air quality is an important indicator of evaluation of environmental health. How to objective and comprehensive evaluation of the air quality is the key problem. According to the environmental quality of Shihezi,the Sunshine Bilingual School and the Shihezi south district thermal power plant were used as experimental areas to collect carbon dioxide,carbon monoxide and PM2.5 concentration data. The criterion of Mrs Grubbs and Pearson product moment coefficient were used to complete data filtering and correlation analysis. Then,the mathematical conversion model of measured data and official website data is established,and the air quality level evaluation model is constructed by using the Analytic Hierarchy Process (AHP). Data from the experiment results show that the system with the website data fitting model is high precision;correlation are above 0.97;the accuracy of the environmental grade is 93.3%,which verifies the reliability and effectiveness of the evaluation model.
