| 摘要: | 溫泉資源資料為溫泉管理之重要科學依據，臺南關子嶺溫泉尚在起步階段。2015 年水利署委託嘉南藥理大學建立溫泉監測站，本研究整理這兩年間之監測數據，以供了解雨量、水位、水溫之間的關係。
關子嶺溫泉共有兩個溫泉露頭，分別位於火王爺廟與寶泉橋。2016年2月6日發生美濃大地震，火王爺廟露頭停止出水，寶泉橋則出現第二個露頭。
監測結果顯示，降雨量與溫泉水位上升呈現正相關，當月若雨量較多，水位上升，反之下降。寶泉橋露頭有引水溝，連通露頭及儲槽，監測點位於引水溝，水位介於269.7m至270.0m之間，高於270m會溢流出溝外。
泉溫與降雨量呈現負相關，寶泉橋溫度介於74℃～65.4℃之間，露頭因雨水混入，地面逕流造成水位上升泉溫下降，最高雨水可占泉水三分之二。寶泉橋的流量差異很大，介於23cmd至190cmd之間，水深越深，則流量越大。
寶泉橋導電度16,520 uS/cm，pH值8.94，含泥量乾重30至70 g/l。火王爺導電度14,250 uS/cm，pH值8.88，含泥量乾重0.49g。由此可見，寶泉橋與火王爺的溫泉源頭應為同一來源。
The hot spring monitoring data provides important scientific bases for its sustainable management. However, there is no monitoring of water level and temperature before 2015 in Guanziling, Tainan. The Water Resource Agency had entrusted our research laboratory in Chia Nan University of Pharmacy & Science to set up a hot spring monitoring station. This essay uses data collected during these 2 years to explore the correlations among the rainfall, water level and water temperature.
There are 2 hot spring outcrops in Guanziling, Tainan. One is at Acala Temple and another at Baochuan Bridge. After an earthquake occurred on February 6th, 2015, the Acala Temple source had been stopped, but a new source appeared at Baochuan Bridge.
According to the monitoring data, there is a positive correlation between the rainfall and the hot spring water level. The water level is higher when there is more rainfall. Otherwise it is lower. In the case of Baochuan Bridge, the water level is between 269.7m to 270.0m in the ditch, because the water would flow out if it’s higher than 270m.
On the other hand, there is negative correlation between the spring temperature and the rainfall. The water temperature at Baochuan Bridge is around 74℃ to 65.4℃. When the spring mixed with the rainfall, the spring level will be raised up and the temperature will be reduced. The highest proportion recorded of the rainfall is about 2/3. Discharge of hot spring is between 23 cmd and 190 cmd at Baochuan Bridge. The discharge is greater when the depth is deeper.
At Baochuan Bridge, the conductivity of spring water is 16,520 uS/cm, with pH 8.94, and silt bearing 30-70 g/l. At Acala Temple, the conductivity is 14,250 uS/cm, with pH 8.88, and silt bearing 0.94 g. Thus, based on these evidences, these 2 springs might come from the same source. |
