標題:	四重溪溫泉之降雨與水位定量分析 Study on Water Level and Rainfall in Sihchongsi Hot Spring 四重溪有15家業者，17口溫泉井，抽水造成水位下降，水位升降與降雨和抽水有關，本研究針對四重溪地區溫泉水位、雨量進行探討，建立各監測點的水位之年變化趨勢圖及探討水位、雨量關係，以提供四重溪地區溫泉水資源，永續利用及總量管制之參考。雨量資料來自中央氣象局石門山雨量監測站。以日雨量降雨超過50mm，該天的水位減去前一天的水位，作為該日的水位變化量。本研究分析五個溫泉監測井的水位數據，探討2018年水位和降雨之間的關係。2018年水位變化比對降雨記錄，發現4月至9月各井水位明顯上升，但其4月至5月幾乎無降雨，推測可能原因為泡湯季節已過，用水的需求降低，抽水減少因此水位回升。另外2018年3月底，大山溫泉農場停業，該農場2017年抽用約6萬多噸，全溫泉區總抽用量約21萬噸，其抽用量約占全溫泉區的30%，所以該業者停抽後，造成監測井的水位普遍上升。降雨與水位上升之定量分析，3、4、5號井降雨與水位上升有正比關係，但決定係數（R2）（Coefficient of determinetion）很低，分別為0.0146、0.2724及0.022，可見關係並不明確，推測鄰井抽水的水位升降影響大於降雨效應。 There are a total of 15 hotels and spa houses with 17 hot spring producing wells in Sichongxi hot spring area, southern Taiwan. The fluctuations of water level in hot spring monitoring wells are related to rainfall and withdraw of hot spring well. This study discusses the relation of hot spring water level in the monitoring wells and rainfall. To provide data for management of sustainable use of hot spring water resources in the Sichongxi area.The rainfall data comes from the Shimenshan Rainfall Monitoring Station of the Central Meteorological Bureau. With the daily rainfall of more than 50mm, the water level of that day minus the water level of the previous day is taken as the amount of water level change for that day. This study analyzes the water level data of five hot spring monitoring wells and explores the relationship between water level and rainfall in 2018.The water level changes in 2018 compared with the rainfall records. It was found that the water levels of each well increased significantly from April to September, but there was almost no rainfall from April to May. It is speculated that the possible reason is that the hot spring season has passed, the demand for water has decreased, and the pumping has decreased. In addition, at the end of March 2018, the Dashan Hot Spring Farm closed down. The farm used about 60,000 tons in 2017. The total hot spring area used about 210,000 tons, and its use accounted for about 30% of the whole hot spring area, so the bath house stopped pumping, the water level of the monitoring well generally rises.There is a proportional relationship between rainfall and water level rise in wells 3, 4, and 5, however the coefficient of determination (R2) is very low, with 0.0146, 0.2724 and 0.022, respectively. The results show that the relationship between rainfall and water level is not clear, and may be the effect of pumping of adjacent wells to the fluctuation of water level is greater than the rainfall.
