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 SO

concentration is 24.4μeq/L in 2009,which is about a half of that in 2007. NH

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

is the most important component for neutalization.
