摘要
以合肥市空气质量实时监测面板数据为样本,气体污染物为指标,建立空气质量时空分布模型,从日度、月度和季度三个维度分析不同区污染状况.根据主成分分析综合评价模型,分析庐阳区、明珠广场、三里街等十个监测点主要污染源,并对各区污染程度排序.研究结果表明,NO2和PM2.5是合肥的主要污染物,瑶海区空气质量最差;滨湖新区、董铺水库、高新区、琥珀山庄、明珠广场和长江中路空气污染程度较轻,包河区、庐阳区、三里街和瑶海区的空气污染较重.
Aiming at the problem of air pollution in Hefei,with the index of gaseous pollutants as the starting point,real-time monitoring panel data of air quality in Hefei was selected as the research sample.A spatio-temporal distribution model of air quality is set up to analyze the pollution status in different areas from three aspects of daily,monthly and quarterly;With principal component analysis comprehensive evaluation model,track the main pollution sources of ten monitoring sites in Luyang District,Pearl Plaza and Sanli Street,and sort the degree of pollution in each area：NO2 and PM2.5 are the main pollutants in Hefei,and Yaohai air quality is the worst.Establish the clustering analysis,and the air pollution in Binhu New Area,Dongpu Reservoir,Hi-tech Zone,Amber Mountain Villa,Pearl Plaza and Middle Changjiang Road was relatively light,while the air pollution in Baohe District,Luyang District,Sanli Street and Yaohai District was heavy.
