| 摘 要： | 根据2004～2008年长沙市降水监测资料,对近年长沙市城区降水变化趋势和离子组分进行了分析。结果表明:长沙市城区属重酸雨污染区,酸雨pH虽有逐年升高的趋势,但降水酸度并未明显减弱,酸雨频率仍然较高,酸雨带来的污染尚未得到明显减轻。降水组份中,硫酸根离子浓度占首位,属硫酸型酸雨。 |

| Abstract: | According to rainfall monitoring data from the year 2004 to 2008 in Changsha City,we analyzed rainfall variation tendency and ionic components in Changsha area recent years. The result indicates that the Changsha now is the serious acid rain region, though the pH of rainfall show increasing trend recent years,but rainfall acidity remains and high frequency of Acid rain, Pollution from acid rain have not be significantly reduce. In components of rainfall, the highest ionic concentration is found SO2-4, pollu... |
