摘　　要：基于2014-2019年海宁市气象监测与环境空气质量监测数据,本文运用SPSS软件进行相关回归分析,全面分析AQI与气象要素、其他评价因子(AAQI和HAQI)的关系,探究不同气象因素与经济发展对海宁市空气污染的影响。结果显示,在不同气温区间中,除了O_(3)以外,其余5种空气污染物的平均浓度基本随气温T的升高而降低;6种污染物的浓度都在相对湿度U≥90%时出现最低值,而除了SO_(2)以外,其他5种污染物的浓度都在60≤U<70%时出现最高值;风速V越大,PM_(2.5)、PM_(10)、SO_(2)、NO_(2)和CO的浓度越小,空气质量越好,而风速V对O3浓度的影响不大。研究发现,AQI与AAQI的决定系数R^(2)为0.987,AQI与HAQI的决定系数R^(2)为0.811,HAQI与固定资产投资存在一定的相关性。Based on the 2014-2019 Haining weather monitoring and ambient air quality monitoring data,this paper uses SPSS software to perform correlation regression analysis,comprehensively analyze the relationship between AQI and meteorological elements and other evaluation factors(AAQI and HAQI),and explore the impact of different meteorological factors and economic development on air pollution in Haining.The results show that in different temperature intervals,except for O3,the average concentrations of the other five air pollutants basically decrease with the increase of temperature(T);the concentrations of the 6 pollutants all have the lowest value when the relative humidity U≥90%,and except for SO_(2),the concentrations of the other 5 pollutants all have their highest values when 60%≤U<70%;the higher the wind speed(V),the lower the concentration of PM_(2.5)、PM_(10)、SO_(2)、NO_(2) and CO,and the better the air quality,the wind speed(V)has little effect on the O3 concentration.The study finds that the coefficient of determination R^(2) of AQI and AAQI is 0.987,and the coefficient of determination R^(2) of AQI and HAQI is 0.811,HAQI has a certain correlation with fixedasset investment.
