| 摘 要： | 空气质量直接关系到人类的身体健康以及自然界其他生物的生存状况.在人们越来越重视自身的生存环境的情况下,对于空气质量的关注也就越来越多.对于空气质量的研究有助于了解空气污染的主要原因,从而利用自然条件以及建设环保设施来改善空气质量.该文以西昌市的空气质量为例,建立了变系数模型,并使用局部线性估计方法拟合模型,定量分析西昌市气象因素随季节变换对当地空气质量影响程度的变化.

| Abstract: | Air quality is directly related to human health and the survival condition of other creatures in nature. People pay more and more attention to its own survival environment, and more and more attention to the air quality. Researching air quality helps us to understand the main cause of air pollution, and use natural condition and the construction of environmental protection facilities to improve air quality. In this paper we used a case study of Xichang to establish the variable coefficient model, and used the local linear estimation method to fit model, and the changes of influences of meteorological factors along with the season transformation were also analyzed quantitatively. |
