Research on Sitnation and Variation Characteristics of Environrnental Air Quality in Weifang City

Weifang Ecological Environment Moritoring Center, Weifang 261041, China

摘要: 文章分析了潍坊市区大气环境空气质量时空分布特征,监测的污染物为PM₁₀、SO₂、NO₂、PM_2.5、O₃、CO共6项。2015~2017年SO₂和NO₂年均浓度基本呈下降趋势,均低于国家二级标准,SO₂/NO₂值呈逐年下降趋势;PM₁₀、PM2.5浓度时间变化规律基本相同,呈现夏季浓度较低、冬季浓度较高;CO年均浓度呈小幅下降趋势;O₃-8h年均浓度在109~119μg/m³之间,臭氧的污染不容忽视。从空间分布来看,8个自动监测点位周边情况不同,均能反映其区域环境空气质量状况。

Abstract: This paper analyzes the spatial and temporal distribution of environmental air quality in urban district of Weifang, and the monitored pollutants include PM₁₀, SO₂, NO₂, PM_2.5, O₃ and CO. The average annual concentrations of SO₂ and NO₂ from 2015 to 2017 basically declines, which are lower than the national second standard, and the value of SO₂/NO₂ decreases year by year. The concentration variations of PM₁₀ and PM_2.5 have basically the same trend, showing lower concentration in summer and higher concentration in winter. The average annual concentration of CO shows a small downward trend, while that of O₃-8 h is between 109 μg/m³ and 119 μg/m³. Ozone pollution can't be ignored. From the perspective of spatial distribution, the eight monitoring points in different positions can reflect the environmental air quality of their regions.
