气象因子与区域大气污染浓度间的关系建模研究

Modeling and Analysis of the Relationship Between Meteorological Factors and Regional Air Pollution Concentration

在大气污染日益严峻的当下,改善空气质量水平已经成为了现阶段的重点问题。为此,建立气象因子与区域大气污染浓度间关系分析模型。分别规定气象因子与大气污染物质的物理含义,并确定污染浓度的实际等级,从而描述物理量的定义与处置。然后通过样本选择的方式区别解释变量与被解释变量,再以样本数据特征统计结果为标准,完成气象因子与区域大气污染浓度间的关系建模。根据气象因子在大气中的分布变化规律可知,气温、气湿、气压均会影响污染浓度的实际数值水平。

With the increasingly severe air pollution,improving the air quality level has become a key issue at this stage.To this end,the relationship analysis model between meteorological factors and regional atmospheric pollution concentration is established.The physical meanings of meteorological factors and atmospheric pollutants are defined respectively,and the actual levels of pollution concentrations are determined,so as to describe the definition and disposal of physical quantities.Then,the model of the relationship between meteorological factors and regional atmospheric pollution concentration is completed by differentiating explanatory variables and explained variables through sample selection,and taking the statistical results of sample data characteristics as the standard.According to the distribution of meteorological factors in the atmosphere,air temperature,air humidity and air pressure all affect the actual numerical level of pollution concentration.
