摘要： 通过对乌鲁木齐市月耗煤量、逆温层厚度及平均风速与大气污染物SO2，NO2，PM10月浓度的相关性分析，得出耗煤量和逆温层厚度是导致大气污染物浓度增加的主要原因，且采暖期逆温层厚度对大气污染物浓度的影响远大于燃煤排放造成的影响。对污染物月浓度与气象因子及耗煤量进行多元线性回归分析，并建立模型Y=a+b1X1+b2X2+b3X3，得出逆温层厚度对不同污染物的浓度影响存在差异，其中逆温层厚度对大气污染物浓度的影响较风速更显著。风速在非采暖期对污染物的扩散和稀释作用大于采暖期，对各污染物浓度的影响差异较大，关系较离散。

Abstract: The relationships among monthly average concentrations of air pollutants (SO2, NO2 and PM10) over Urumqi and the monthly coal consumption, inversion layer thickness and monthly average wind speed were investigated. It was found that coal consumption and inversion layer thickness were the dominant factors affecting the diffusion of air pollutants over Urumqi. Based on these analyses, the regression models were developed to describe the effects of coal consumption, inversion layer thickness and wind speed on the concentrations of air pollutants. It was concluded that the effect of inversion layer thickness on different pollutants was different, and wind speed played more important role in diffusion of air pollutants during heating period than during nonheating period.

Key words: air pollutant, quantitative model, inversion layer, coal consumption, Urumqi
