| 摘 要： | 依据湖南省1993-2000年监测酸雨的数据资料,对湖南省酸雨的变化特征、分布及目前的状况和成因进行了分析.结果表明,湖南省降水pH值小于5.0的强酸性降水地区主要分布在湘中南和西南部,弱酸性降水区则分布在湘中地区;除怀化和洪江两地外,湖南降水阴阳离子基本平衡;湖南地区降雨为典型的硫酸型降雨,酸雨的形成主要受局地源的影响,其次是土壤、地形、气候和中远距离的输送等自然因素的作用.笔者认为能源结构和工业污染物等社会因素在酸雨的形成中具有决定性的作用.

| Abstract: | The variational characteristics,distribution,present situation and causes of acid rain are analyzed based on the monitoring data from 1993 to 2000 in Hunan Province.The results show that the central\|south and southwest of Hunan are the main acid rain regions with pH value less than 5\^0 and the centre of Hunan is the region where the rainfall is subacid.The ionic balance of precipitation is generally kept except for Huaihua and Hongjiang.The rainfall is typically sulphur\|type rain in Hunan.The formation of acid rain is mostly influenced by the local sources as well as other natural factors such as earth,landform,climate and transportation of air pollutants.Authors suggest that social factors such as energy structure and industrial pollutants have the decisive effects on the acid rain formation in Hunan Province. |
