摘　　要：在分析高温热浪时期的空气污染特征时,空气污染数据样本量不足,容易导致分析结果出现较明显的失真情况,为此提出夏季高温热浪期间空气污染特征分析。以济南市为例,采集气象站点的夏季高温历史数据,筛选出以往高温热浪事件并统计其强度、频次和空间分布情况,将其与各地区的空气污染数据相结合,计算出空气污染指标与高温气象指标的关联度,建立空气污染特征分析模型,完成对目标地区的空气污染特征分析。实验结果表明:在不同的实验环境下,提出的分析方法能够保证分析数据相关系数高、平均偏差小、一致性水平高,整体分析效果更好。When analyzing the characteristics of air pollution during high temperature and heat waves,the insufficient sample size of air pollution data can easily lead to significant distortions in the analysis results.Therefore,an analysis of air pollution characteristics during high temperature and heat waves in summer is proposed.Taking Jinan City as an example,the paper collects historical data of summer high temperatures from meteorological stations,screens out past high temperature heat wave events,and calculates their intensity,frequency,and spatial distribution.It then combines them with air pollution data from various regions to calculate the correlation between air pollution indicators and high temperature meteorological indicators to establish an air pollution characteristic analysis model,and complete the air pollution characteristic analysis of the target region.The experimental results show that the proposed analysis method can ensure high correlation coefficient,small average deviation,high consistency level,and better overall analysis effect in different experimental environments.
