The study probes into the changes in equivalent concentration of inorganic salts and carboxylic acids in different rainfall patterns in the seasons (Spring, plum rain, Summer, typhoon peripheral circulation, typhoon, dry Autumn and Winter) in the outskirts of Tainan County between January and the end of December 2011. In the outskirts of Tainan County, the rainfall patterns rank in such an order as typhoon peripheral circulation, Summer, typhoon, plum rain, dry Autumn and Winter and Spring in terms of rainwater pH value, 6.03, 6.02, 5.84, 5.70, 5.61 and 5.54 respectively.TotalequivalentconcentrationofinorganicsaltsiseqLinSpring,eqLinplumrain,eqLinSummer,eqLintyphoonperipheralcirculation,eqLintyphoon,and eq Lin dry Autumn and Winter; and in the equivalentconcentrationratiointhesesixrainfallpatterns,thenegativeionsaredominatedbyHCO,ClandSO4,andthepositiveironsbyNa+(6.14~19.81%),Ca2+(7.90~29.28%)andMg.TotalequivalentconcentrationofcarboxyateiseqLinSpring,eqLinplumrain,eqLinSummer,eqLintyphoonperipheralcirculation,eqLintyphoon,andeq Lin dry Autumn and Winter; and the total equivalent concentration ratio varies between 0.55 and 1.62%, in which acetate (42.95~75.86 %), formate (2.95~22.29 %) and oxalate (8.57~22.48 %) predominate.
