摘　　要：建立一个一维大气化学模式,利用该模式模拟 O_3等微量气体的日变化和 O_3的一些敏感性试验。结果表明:CH_4和 CO 的增加会使 O_3增加,水汽增加将使 O_3减少;温度升高使自由大气中O_3减少,而使边界层中 O_3增加;太阳辐射的加强使自由大气中的 O_3减少,边界层中 O_3增加。最后,研究了边界层结构对大气微量气体分布的影响。结果表明,模拟低层大气微量气体的变化需要考虑边界层结构的影响。An one—dimensional atmospheric chemical model is developed.Using the model,diurnalvariations of ozone and other trace gases have been simulated,and several sensitive experimentshave been made.The results show that increments of CH_4 or CO cause O_3 to increase and in-crement of water vapour causes O_3 to decrease;in the free atmosphere O_3 decreases with a risein temperature,but in the boundary layer O_3 increases;when solar radiation enhances,O_3 de-creases in the free atmosphere,but in the boundary layer O_3 increases.In addition,the influenceof the boundary layer on the distribution of trace gases is studied.It is found that the effect of theboundary layer has to be considered in the simulations for the variation of trace gases in the low-er atmosphere.
