Abstract:	本研究將可提供屏東地下水鹽化區最新的水位及最基本的導電度數據，以供了解鹽化區地下水的流向及機制，作為治理地下水鹽化的依據與參考。 The densities of groundwater within observation well may be different in those areas with saline aquifers. The hydraulic heads should be correlated to the density variation within observation wells, i.e. the equivalent freshwater head (Post et al. 2007). Chiu et al. (2021) use freshwater heads to analyze flow directions in saline aquifers of the Pingtung Plain. In this article, I am the correspondence author, also shows that electric conductivities (EC) within observation wells have variations vertically and seasonally. This study will focus on the vertical EC variation in saline aquifers with a total of 26 observation wells with 6 measurements during Sept. 2022 to May 2023. The results of this study show most of those wells have seasonal EC variation. The EC values are higher in low head period (Sept. to Dec. 2022) and lower in high head period (Jan. to May 2023). Those data suggest that sea water intrusion are going on and cause the higher EC in those wells.
