浅析攀枝花市2015～2017年气象要素对空气污染的影响

利用2015～2017年攀枝花市污染因子和气象要素实测数据，运用GIS技术、相关分析以及统计分析等方法，分析攀枝花市空气污染因子和气象要素的时空特征及相关性。结果表明:攀枝花市首要污染物为PM₁₀，其次是NO₂;秋冬以PM₁₀和NO₂污染为主，春夏PM₁₀和O₃为主。不同季节，各气象要素对本地空气质量的影响程度及空间分布存在明显差异。弄弄坪一带PM_2.5和SO₂、CO浓度偏高，市中心炳草岗一带PM₁₀、O₃和NO₂浓度偏高。结合本地发展规划和实际情况，根据气象要素分析，为攀枝花市分区分季节的防污减排决策提供气象参考。

Analysis of the Impact of Meteorological Elements on Air Pollution in Panzhihua City from 2015 to 2017

Based on measured data of pollution factors and meteorological elements from 2015 to 2017,this paper analyzed the spatial and temporal characteristics and correlation of air pollution factors and meteorological elements in Panzhihua City by using GIS,correlation analysis and statistical analysis.The results showed that the primary pollutant in Panzhihua City was PM₁₀,followed by NO₂;PM₁₀and NO₂were the main pollutants in autumn and winter,while PM₁₀and O₃were the main pollutants in spring and summer.In different seasons,the influence degree and spatial distribution of meteorological elements on local air quality were significantly different.The concentrations of PM_2.5,SO₂and CO were higher in Nongnongping area,and the concentrations of PM₁₀,O₃and NO₂were higher in bingcaogang area.Combined with the local development planning and the actual situation,according to the analysis of meteorological elements,this paper provides meteorological reference for the decision-making of pollution prevention and emission reduction in Panzhihua City.
