| 摘 要： | 运用多元线性回归分析的方法对北京沙尘气溶胶质量浓度观测资料和相关气象资料进行了分析，结果表明北京沙尘气溶胶质量浓度与尘暴、浮尘、降水和大风四种气象要素密切相关。在此基础上给出利用常规气象资料计算沙尘气溶胶质量浓度的计算公式，并进一步计算了１９７１～１９９６年北京春季月平均沙尘气溶胶质量浓度。结果表明，从１９１～１９８９年沙尘气溶胶质量浓度总体呈递减趋势；１９９０年以后，沙尘气溶胶质量浓度有所增加。

| Abstract: | Mineral aerosol data was analysed with meteorological data of Beijing by use of multiple linear regression analysis, it indicated that there was a close relation between the monthly concentrations of mineral aerosols and the frequency of relative meteorological elements. Based on the multiple linear regression equation derived in this paper, regular meteorological data can be used to estimate the concentration of mineral aerosol. Calculated results indicated that the mineral aerosol concentrations over Beijing showed a decreasing tendency between 1971 and 1989, but this tendency slowed down during the nineties. |
