京津唐大气环境及其区域研究

The Atmospheric Environmental and Its Regional Research in Beijing-Tienjin-Tangshan

本论文分析了北京、天津和唐山主要大气污染物随时间和地点的变化,并进一步分析了它们的污染特征。在此基础上,我们利用气象资料,污染源等基础资料,通过大气污染物主轴浓度模式计算了一年四个季节二氧化硫浓度分布,并且分析了全区二氧化硫分市特征及相互影响。区域大气环境是大气环境中新的课题,本文提供了使用燃煤密度、模式计算和污染系数来综合考虑大气环境区划的方法,为大气环境分区提供了参考手段。

The dependency of the variation of the main atmospheric pollutants on the time and the location in Beijing, Tianjin and Tangshan area is described in this paper, and a futher analysis of the characteristics of atmospheric pollutants is also carried out With the aid of the basic information, such as meteorological data, sources of pollutants etc, the distribution of SO2 concentration in the whole area for the four seasons in a year is calculated with the model of the main axis concentration of atmospheric pollutant, and the characteristics of the distribution of SO2 in the whole area is also analyzed, including the mutual influence between some part of the area. The division into districts of atmospheric environment is a new subject in the atmospheric environment. A method for division into districts by the aid of the model's calculation, the density of coal burnt and the pollution factor is suggested by us. This method may be used as a reference measure.
