Abstract:	本研究探討台南郊區2011年1月~12月底止，各季節降雨型態(春季、梅雨、夏季、颱風外圍環流、颱風、秋冬乾季)之無機鹽類及羧酸之當量濃度變化。在台南郊區不同季節降雨型態其pH由高至低依序為颱風外圍環流、夏季、颱風、梅雨、秋冬乾季、春季，其pH值分別為6.03、6.02、5.84、5.70、5.61、5.54。無機鹽類在六種降雨型態之總當量濃度分別為春季eq L、梅雨eq L、夏季eq L、颱風外圍環流eq L、颱風eq L、秋冬乾季eq L，且六種降雨型態之當量濃度比例陰離子均以HCO、Cl及SO4為主要成份，陽離子則以Na(6.14~19.81%、Ca(7.90~29.28%)及Mg為主要成份。羧酸在6種降雨型態之總當量濃度分別為春季eq L、梅雨eq L、夏季eq L、颱風外圍環流eq L、颱風eq L、秋冬乾季eq L，總當量濃度比例介於0.551.62 %，其中以acetate(42.95~75.86 %)、formate(2.95~22.29 %)、oxalate(8.57~22.48 %)為最主要物種。 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.
