    摘要: 垂直井溫除了受到上下邊界溫度的控制,也受到地下水流動的影響,因此可用來找尋溫泉地熱資源、了解地下水流動或是全球暖化的地區性影響。本研究量測嘉南高觀測井的垂直井溫及表面土壤溫度,主要有三個目標:(1)了解本研究區表面土壤溫度(SST)的變化及影響因素: 例如地表覆蓋及氣溫的影響;(2)評估淺層暖化的程度及其可能的原因;(3)以溫度分布推算地下水流場(流向及流速)及應用。 本研究區的 SST比氣溫高,所以除了氣溫影響,日照也有影響。有陰影遮蔽,例如樹林及建築物,SST比較接近氣溫;沒有遮蔽,例如裸土,直接日曬會造成SST升高。2018-2017之SST實測值變化以降低為主,可能因為氣溫降低的影響。 由垂直井溫推算的表面溫度改變,其中94%的井溫度呈現暖化,增加溫度最大可達4.5℃,百年來氣溫增加約2 ℃ ,因此大於2℃的增溫,應該和土地利用有關,例如樹林砍伐、水泥及空地增加。 使用垂直井溫推算北門井第一阻水層的垂直流速,誤差值MAEs < 0.2 °C時,向下的垂直流速大約0.5-6 × 10-8 m/s。誤差最小的模擬值MAE 為 0.032 °C, 垂直流速3.5×10-8 m/s。以一平方公里的第二含水層計算,垂直流入的水量是水平方向的50倍。
    The temperature-depth profile (TDP) is affected by upper and lower boundary and groundwater flow which is a common method for exploring hot spring and geothermal resource and evaluate temperature change of surface soil. The study collects TDP and surface soil temperature (SST) by using the groundwater monitoring wells in Chianan and Kaohsiung area. The results show that SSTs are generally greater than the air temperatures. The SSTs are greater in bare soil and no shading area. There are 94% of wells with a warming trend in surface soil temperature from the TDP data. The vertical velocity is 0.5-6 × 10-8 m/s in the first aquitard of the M1 well with MAEs<0.2 °C while the vertical velocity is 3.5×10-8 m/s with the minimum MAE of 0.032 °C. The vertical groundwater flux is 50 times larger than the horizontal flux within an area of one square kilometer.
