摘要

本研究之目的為應用地下水歷線及同位素分析法，估算地下水系統之水平衡情形並推估雨水、河水與區外地下水等各補注源之比例與補注量。本研究將所建立之方法應用於屏東平原，研究結果顯示西元1999至2008之年平均蓄水變化量為0.11億噸，年平均抽水量為14.08億噸，年平均總補注量為17.57億噸，而年平均流失量則為3.38億噸；總補注量中，雨水補注佔55.9%，河水補注佔14.3%，而區外地下水補注則佔29.8%。

This study applied groundwater hydrograph and isotope analysis method to estimating groundwater balance and evaluating the recharge from sources including rainfall, river seepage and inflow through the boundary in a groundwater system. The area studied in this research is the Ping-Tung plain. The estimation results show that, from 1999 to 2008, the average annual change in storage was 0.11 hundred million tons, the average annual withdrawal was 14.08 hundred million tons, the average annual recharge was 17.57 hundred million tons and the average annual groundwater loss was 3.38 hundred million tons. Among all the recharge sources, rainfall accounts for 55.9 of groundwater recharge; river seepage, 14.3; and inflow through the boundary, 29.8.
