摘要
基于生态环境部、山东省生态环境厅公开发布的2019年度环境空气质量报告,使用统计软件SPSS25.0分析泰安市城区PM2.5、PM10、SO2、NO2、CO、O36项指标月均浓度值及空气质量综合指数(简称Isum)的变化趋势;探讨首要污染物PM2.5与PM10、SO2、NO2、CO、O3、Isum的相关关系;建立Isum与PM2.5、PM10、SO2、NO2、CO、O3的多重回归方程;通过t检验分析泰安市与毗邻城市山东大学、济宁市月均浓度值的差异性,并计算P值(t值);评价泰安市辖区泰山区、岱岳区、高新区空气质量的均质性;依据《GBT 3840-91制定地方大气污染物排放标准的技术方法》核算泰安市城区大气环境容量;最终为大气污染防治提供科学精准的理论支撑。
Based on the 2019 Ambient Air Quality Report publicly released by the Ministry of Ecology and Environment,and the Department of Ecology and Environment of Shandong Province,the statistical software SPSS25.0 was used to analyze the monthly average concentration of six indicators,namely PM2.5,PM10,SO2,NO2,CO,O3 and the comprehensive air quality index((Referred to as Isum).The correlation between the primary pollutant PM2.5 and PM10,SO2,NO2,CO,O3,Isum was explored.The multiple regression equations of Isum and PM2.5,PM10,SO2,NO2,CO,O3 were established.The difference in monthly average concentration values between Tai’an City and neighboring cities Jinan City and Jining City by t test were tested.The P value and t value were calculated to evaluate the homogeneity of air quality in Taishan District,Daiyue District,and High-tech Zone of Tai’an City.In accordance with the"Technical Methods for Formulating Local Air Pollutant Discharge Standards"(GBT3840-91),the atmospheric environmental capacity of Tai’an City was calculated.The results would provide scientific and accurate theoretical support for the air pollution prevention.
