摘要: 为了了解鼎湖山降水中无机离子的变化情况,对2007和2009年鼎湖山降水无机化学成分进行观测分析,结果表明,2007和2009年鼎湖山降水pH平均值分别为4.10和4.38,变化不明显。降水离子中首要离子为SO2-4,2007年和2009年浓度分别为127.9 μeq/L 和88.8 μeq/L。2009年NO-3离子浓度为24.4 μeq/L,大约是2007年49.3 μeq/L的一半。比起2007年,2009年SO2-4和NO-3都有不同程度的降低。NH+4的变化不是很明显,两年分别为65.2 μeq/L和60.2 μeq/L。鼎湖山的降水仍是硫酸型,不过有向混合型转变的趋势;同时也发现,NH+4对鼎湖山降水的中和作用最为主要。

Abstract: Inorganic chemical components in rainfall during 2007 and 2009 in the Dinghu Mountain were analyzed in this paper.The results show that acidity has no large change during 2007 and 2009. The pH values are 4.10 and 4.38 in 2007 and 2009 respectively. The most important component is SO2-4,with 127.9 μeq/L and 88.8μeq/L in 2007 and 2009 respectively. NO-3 concentration is 24.4μeq/L in 2009,which is about a half of that in 2007. NH+4 shows little change. The rainfall in the Dinghu Mountain is still the type of sulphate, which is tending to be a mixing type (mixing of sulphate and nitrate). It is also found that NH+4 is the most important component for neutalization.
