| 摘 要： | 根据对湖北省西部宜昌、襄樊、巴东、十堰等城市自然降水pH值的检测结果,对降水pH值变化、时空分布,降水的化学成分、酸雨出现时的风与气象条件、酸雨与降水云类的关系进行了详细的分析。分析结果表明:酸雨形成与当地的地理条件和气象因子有关。稳定的大气环境对酸雨形成有利,较强的逆温和静风频率,可以为当地降水的二次酸化提供有利条件。各地酸性降水化学成分中阴阳离子SO42-/NO2-比值表明,西部城市酸雨具有典型的硫酸型特征。巴东监测的时间较短,但酸雨年出现频率有上升的趋势,并且酸雾出现的几率比较大。襄樊、十堰酸雨出现频率较低与雨水中有较高浓度的阳离子有关。

| Abstract: | Using the data of pH of rain in Yichang,xiangfan,badong,shiyan city,the change of PH,the space-time distribution,chemic components,the meteorological condition of acid rain and the relation with rain cloud were analysed.The result shows that acid rain is relative with geographical and meteorologic condition,steady atmosphere environment is in favor of acid rain,strong inversion and aerostatic frequency can provide the conditions of rain's the second acidification,the area chemic components of acid rain anion and cation SO42-/NO2 shows,westward city acid rain has the character of vitriol.The observation time of Badong city is shorter,but the frequency of acid rain year is increasing,and rate of acid fog appearance is relative big,the rate of acid rain in xiangfan and shiyan is smaller,It is correlative to higher cations of rain. |
