Abstract:	本研究目的為了解天悅溫泉飯店與四重溪溫泉會館，其兩間業者新申請之三口溫泉井，是否造成舊有鄰井的干擾，及短時間或長時間內的干擾程度,是否會影響到舊有井使用的效率,造成溫泉資源使用上的浪費以及溫泉長期水位影響。將收集到的長期水位變化資料，應用各種理論及公式(例如: 達西定律，泰式公式及雅各公式…等並假設各種T值及S值，計算分析其各假設狀況的洩降量及干擾量，了解其干擾程度。在預測狀況中，狀況1-1，得到天悅兩井互相干擾程度，假設不同T值之下，洩降量大概是0.8m~4.5m。狀況1-2，天悅溫泉飯店兩口井與四重溪溫泉會館一口井互相干擾問題，及對鄰近8口井干擾問題，洩降量大約是3.03~3.79m，狀況1-3，預估鄰近11口井同時抽水之洩降量，總洩降量大約6.5~22.8m，，造成洩降的主要原因為大抽水量、長期抽水、近距離這3個原因。狀況二，長期一年之干擾影響，不管長期或短期抽水來看，停止後水位皆會明顯回升，雨季時，水位亦會快速回升，如能將抽水總量管制，不超過補充量，雖新設三口井，但對溫泉區長期水位(例如一年)並沒有影響。 Szchungshi hot spring is one of the most important spa destinations in Taiwan. The increasing hot spring water withdrawn and wells drilled for recreation use are causing the depletion of hot spring resources. The purpose of this study is to evaluate the drawdown of three new installing wells by Theis equation. The hydraulic conductivity and storage coefficient are calculated from water pressure data of four hot spring production wells. For the condition 1, the drawdowns of two new wells of the Tin Yuet spa resort are about 0.8-4.5 m during a one-day pumping period with a hydraulic conductivity of 20-140 m2/day. For the condition 2, we estimate the drawdonws by three new wells in a one-day pumping period are about 2.5-3.0 m with a hydraulic conductivity of 80 m2/day and a pumping rate of 120 cmd. For the long term, i.e. one year, the decline or recover of water pressure in the hot spring aquifer depend on the rainfall and total extraction rate. Water pressure will drop rapidly in the dry season and when the extraction volume exceeds the natural recharge rate, and recover in the wet season.
