影响环境空气质量的PM2．5与相关因素的关系研究

上海地区空气中细颗粒物浓度与相关因素的研究表明,空气中臭氧、一氧化碳、二氧化硫浓度及温度与PM2.5指标值有着密切的关系,其中一氧化碳、二氧化氮、二氧化硫浓度与PM2.5指标值有很强的正相关关系。因子分析和回归分析表明,臭氧、一氧化碳、二氧化氮、二氧化硫浓度及温度的潜在内涵因子人类主动行为因素和自然因素,两个因子与空气中细颗粒物关系显著,尤其是第一主因子人类主动行为因素,治理环境空气污染可从人类主动行为因素突破。

Study of the Relationship between PM2.5 and Related Factors Which Impact Air Quality

It takes Shanghai for example to do the research on the relationship between the density of fine particles in the air and related factors.Through the correlation analysis, it indicates that the PM2.5 indexes are closely related with the density of ozone, carbon monoxide, nitrogen dioxide sulfur dioxide in the air and the temperature.In addition, the density of ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide in the air has a strong positive relationship with the PM2.5 indexes.Using the factor analysis and re-gression analysis comprehensively, we find two potential factors of the density of ozone, carbon monoxide, nitrogen dioxide, sulfur di-oxide in the air and the temperature which is the human behavioral factor and the natural factor .The two factors have significant asso-ciation with the density of fine particles in the air , especially the human behavioral factor which is the first main factor .In conclu-sion, controlling air pollution can make breakthrough from the human behavioral factor.
