地下溫度場可以藉由量測水井、溫泉井或石油探井等鑽井之垂直向井內溫度得知。高雄鄰近平原區並沒有地溫研究；本研究藉由水利署地下水觀測井之垂直井溫量測評估溫泉蘊藏範圍。
利用現有之地下水觀測井，在105年12月完成測量井溫，繪製各井的垂直溫度剖面，整理地溫分布狀況；另藉由水利署從民國89年~93年間對高雄鄰近平原區地下水水質檢測之數據分析其導電度，綜合水溫與水質，推估高雄鄰近平原區的溫泉蘊藏深度。
本研究發現，高雄鄰近平原區18個觀測站，地溫之水平分布以五甲站的溫度最低，80m深的溫度約25.33℃，最高溫為省躬，深度225m 達33℃，導電度10326μS/cm。另外有其他四口觀測井導電度符合溫泉標準，溫度也接近30℃： 鹽埕井推估到260m、 竹滬井推估到230m、 成功井推估到180m及仁德井推估到280m的深度。
本研究也發現，高雄鄰近平原區18個觀測站，有一半都位於地下水全區管制範圍內，另有9口井位於部分管制範圍內，所以在未來對於這幾口井可以再做進一步的監測數據。 The underground temperature field can be obtained by measuring the vertical well temperature of wells such as wells, hot spring wells or oil exploration wells. There is no geothermal study in the plain area near Kaohsiung. In this study, the vertical well temperature measurement of the groundwater monitoring well was used to evaluate the hot spring reservoir range by the Water Resources Agency .
Use existing groundwater monitoring wells to complete measuring well temperature in December of 2016, and draw the vertical temperature profile of each well, then finish the distribution of ground temperature. The electric conductivity of the groundwater quality test in the adjacent plain of Kaohsiung was analyzed by the Water Resources Agency from 2000 to 2004. To comprehensive water temperature and water quality, we could estimate the depth of hot springs in the adjacent plains of Kaohsiung.
The research found that a total of 18 monitoring wells in the adjacent plain of Kaohsiung, the lowest horizontal temperature distribution is at the Wujia Well, and the temperature at the depth of 80m is about 25.33℃. The highest temperature is at the Sheng-gong, the depth is 225m up to 33℃, and the electric conductivity is about 10326μS/cm. In addition, there are four other monitoring wells that might meet the hot spring standards and the temperature might be close to 30℃. The Yan-cheng is estimated to be 260m, and the Zhuhujing is estimated to be 230m. The Cheng-gong well is estimated to a depth of 180m and the Rende well is estimated to a depth of 280m.
This study also found that half of 18 monitoring wells in the adjacent plain of Kaohsiung are within the control of the groundwater zone, and another 9 monitoring wells are not settled in the groundwater control zone.
Therefore, further monitoring data can be made for these wells in the future.
