Abstract:	近年投入溫泉產業研究的專家學者發現：長久以來溫泉區開發普遍缺乏管制，普遍存在溫泉泉水超抽的現象，致使溫泉水位下降。溫泉的水位，水質與溫度可能會隨著降雨量，淺層地下水的混入，不同的季節或地下水抽用型態的不同，而有短期或長期的變化，因而了解當地的溫泉區概況，才能達到溫泉資源永續利用。本研究方法以礁溪地區設立13個監測站，於監測站中置入儀器觀測其水位與水溫的變化，建立水位與水溫的趨勢圖，最後加入不同雨量站雨量探討雨量、水位、水溫之間的關係。研究顯示，無法推測監測井水位受山區降雨或平地降雨何者之影響較明顯，只能推測降雨量與水位上升量有明顯正相關。比對降雨與溫泉水位水溫歷線之關係，可發現除了少數降雨事件以外，在各場次降雨的同一天，溫泉水位從低點回升，水溫從高點下降，並於降雨後數天內水位上升到高點，水溫下降到低點，然後又開始回復，明確顯示降雨與補注之因果關係。水位年變化比對年降雨記錄，發現年平均水位隨著年降雨量增加呈現上升趨勢，監測井的水位與降雨有連動關係，因此豐水年或枯水年應對溫泉補注有相當影響。 AbstractRecently the experts who devoted to the study of hot spring industry have discovered a common existing phenomenon after the long-term unrestrained development of hot-spring area: over pumping has led to the decrease in hot spring water level. The precipitation, the mix of shallow ground water, different seasons or different types of ground water pumping can cause a long-term or short-term alteration of hot spring’s water level, quality and temperature. Hence, understanding the general situation of local hot spring is crucial for us to achieve sustainable use of hot spring resource.The research method of this paper is to set 13 monitoring stations in Jiaosi Hot Spring and place instruments to observe the change of water level and temperature to draw a run chart. Also, the precipitation of different rain gauge stations is added into the discussion of the relationship between precipitation, water level and the temperature .The research indicates that it is unable to presume whether the monitored well water level is obviously influenced by the precipitation of mountain area or the ground level area. Therefore, it can only presume there is a positive relationship between precipitation and the rate of water level rising. Compare the relationship between the precipitation with hot spring water temperature hydrograph, it shows that the water level of hot spring rose again from the bottom and the water temperature dropped from the peak. After few days of the rainfall, the water level rose to the peak and the temperature dropped to the bottom. Then, it starts to return again. This phenomenon clearly shows the causal relationship between rainfall and recharge. Compare the annual water level change with the annual rainfall record, it is found that annual average water level rise when the annual precipitation increase. Moreover, there is a linkage relationship between the water level of monitoring well and the rainfall. Thus, a high water year or a low water year is influential to hot spring recharge.
