| 摘 要： | 采用一个包含平流层化学、辐射、动力相互作用的二维模式，对地表有机氯排放变化影响平流层的具体过程作出评估，从而确定平流层臭氧对于地表有机氯排放的多耦合响应，也检验了“蒙特利尔议定书”的减排效果。结果表明，以议定书框架协议达成的20世纪90年代地表有机氯排放减少按30％计算，通过输送、扩散和一系列化学反应，导致平流层中上层的各活性化学族的浓度发生变化，稳定后平流层40km到48km经向平均的相对变化率，ClOx减少20％，HOx和NOx增加2％左右，O3恢复5％左右。此外，这些成分变化导致平流层中上层辐射加热率增加，平流层变冷趋势减缓0．6K。 |

| Abstract: | To evaluate the stratospheric process in the response to the increased surface CFCs emissions, some simulations were carried out by the NCAR interactive chemical, dynamical and radioactive two-di-mensional (SOCRATES) model. The investigation shows that when the surface CFCs emissions is re-duced by 30%, which leads to changes of concentrations of various active chemical components in the mid-upper stratosphere, through transportation, diffusion and a series of chemical reactions;after the e-quilibrium of the various components,the relative change rate of active components In the layer from 40 km to 48 km is-20% for CIO_x ,2% for HO_x ,2% for NO_x and 5% for O_3 ,respectively. Those chan-ges result in the increase in radiation heating rate in the mid-upper stratosphere ,thus the cooling trend of the stratosphere is reduced by 0. 6 K. |
