城市中大气环境质量的某些影响因素研究

A STUDY OF SOME FACTORS AFFECTED URBANATMOSPHERIC POLLUTION

本文采用多对多双重逐步回归分析方法和数量化理论对浙江省某大城市大气中ＳＯ２、ＮＯｘ、总悬浮颗粒（ＴＳＰ）的含量随城市五大功能区和四季变化进行了计算和分析．结果表明城郊大气质量明显好于城区，但城区大气污物含量各区基本一致．大气质量变化受季节影响显著．其污染程度由重到经依次排列为：冬季＞秋季＞春季＞夏季．

The numeric relations of SO2,NOx,total suspended particles(TSP)in atmosphere of a city in Zhejiang Province with the urban function zones and different seasons are calculated by multiple to multiple double screen progressively regression and numerical theory.The results show that the air pollution in urban is quite similar anywhere, but is heavier than in its suburban. From heavier to lighter the air pollution in different seasons are: winter>autumn>spring>summer.
