| 摘要: |
| 根据河池市环境保护监测站2005~2010年的大气降水监测资料,分析河池市近年来酸雨变化趋势和特征。结果表明,河池市酸雨的变化趋势总体下降明显,降雨的pH值3.28~8.60,酸雨发生频率为50.1%。河池市的酸雨是典型的硫酸型酸雨,SO42-离子占总量的大部分,其次NO3-离子含量也较高。河池市工业和能源消耗大量煤炭导致SO2和NOx的大量排放是影响河池市酸雨形成的主要因素,汽车尾气中的NOx排放也是影响河池市酸雨形成的重要因素。 |

| Abstract: |
| Accroding to the atmospheric and water monitordata come from Hechi environmental protection monitoring station,the characteristics and tendency of acid rain in Hechi city during 2005 to 2010 was analyzed.The analysis results indicated that in recent years,the trend of acid rain frequency declined.The pH value of rain ranged from 3.28 to 8.60.The frequency of acid rain falling was 50.1%.The atmospheric water component research indicated that sulfate ion was the main ion.The acid rain in Hechi was the typical sulfuric acid rain and the content of nitrate ion was also high.The NOx from car exhaust and SO2 and NOx from coal consumption in Hechi industries were the main reasons for affecting the pH of rain and acid rain formation in Hechi city. |
