Title:	彰雲平原地區地下水水質及溫泉資源評估 Groundwater chemistry and assessment of hot spring resource in Changhua and Yunlin, Taiwan 台灣的溫泉大多分布於山區，平原區因為沖積層覆蓋及地下水冷水影響，大多沒有自然形成湧出的溫泉。平原區的溫泉探勘與開發大都須依賴鑽井，前人已針對嘉南平原及彰雲平原，利用水利署的地下水觀測網資料，探討地溫分布及溫泉蘊藏的可能範圍。其中彰雲平原的地溫分布已有研究，但是並沒有探討水質。根據溫泉法規定，溫泉的溫度除了需大於30℃外，且水質須符合溫泉標準之任一項規定。本研究探討彰雲平原觀測井之水質組成，針對有可能形成溫泉的井，逐項分析各水質是否符合溫泉標準。本研究的水質資料取自地下水觀測網的水質資料庫。研究發現，東石三單層的總溶解固體量，並未達到溫泉標準，但是如果加上東石二含水層的開篩，在同一口井中，同時開篩二含水層，則溫度和總溶解固體可能都可以達到溫泉標準。宜梧三加上宜梧四的兩層含水層的總溶解固體量、氯離子和鐵離子，可以達到溫泉標準。由此可知在不考慮地層下陷區限制，東石與宜梧符合溫泉開發的條件。 Most of the hot springs in Taiwan are distributed in mountain areas. Because of the alluvial layer covering on the plain and the effects of cold ground water, most of the springs in the plain area are not naturally formed. And most of the hot springs’ explorations and developments in the plain area are almost rely on drilling. The researchers before had been used the groundwater observation data from the Water Resources Agency in Taiwan to discuss the possible distribution of ground temperature and hot spring reservations for the Jianan Plain and Zhangyun Plain. The ground temperature distribution of Zhangyun Plain had been studied, however, the water qualities have not been discussed. According to the Hot Spring Law in Taiwan, the temperature of the hot spring must be greater than 30℃, and the water qualities must meet with any kind of the hot spring standards. There for, this study explores the water quality composition of observation wells in Zhangyun Plain, the wells that may form springs, and analyzing whether the water quality meets the hot spring’s standards . The water quality data for this study was taken from the water quality database of the groundwater observation network.The study found that the total dissolved solids in the three monolayers of Dongshi did not meet the hot spring standard, but if the sieve of the Dongshi second aquifer was added and the second aquifer was sieved in the same well, the temperature and total dissolved solids might be All can reach the hot spring standard. The total dissolved solids, chloride ions and iron ions of the two aquifers of Yiwu III and Yiwu IV can meet the hot spring standard. It can be seen that Dongshi and Yiwu meet the conditions for the development of hot springs without considering the limitation of strata depression.
