| Summary: | 碩士 === 嘉南藥理大學 === 觀光事業管理系 === 102 === The purpose of this study is to monitor water pressure and temperature of a total of 4 wells in the Beitou and Xingyilu hot springs for providing data for hot spring water resource management. I measure the temperature profiles, and collect data of water pressure, temperature, pH and electrical conductivities and propose a conceptual model of hot spring aquifer.
The recharge area of hot spring water came from northern and eastern part of the Datun and Chihsingshan mountains. The hot water flows to the south through the aquifer. The data show water pressures were increased while there had rainfalls that suggests the hot spring aquifer is connected with the recharge area. The electric conductivities of hot spring water are 370-600 μS/cm with pH 4-8. There is only one well with pH <4. The geothermal gradient ranges from 0.005 to 0.72 ℃/m. The well with the highest geothermal gradient is near the outcrops of volcanic fumerals which is one of the water sources for Beitou hot spring.
The relationship between the temperature of water of monitoring wells and rainfall: according to the surveillance data from 2012 to 2013, there were more significant correlation between the temperature of water of number fourteen well and rainfall than other wells. That is, comparing with number fourteen well, the temperature of water of the number twelve, thirteen and sixteen well were less correlated with rainfall（＜0.1℃）
