由以往文獻推估礁溪溫泉量大都為總量評估，然礁溪溫泉區溫泉資源並非均勻分佈，對溫泉區進行總量管制亦不合理。本研究為推估礁溪溫泉水量分佈狀況，依據礁溪溫泉監測季報資料，透過徐昇氏多邊形法，將礁溪溫泉區劃分成七個控制分區，利用溫度法推估各分區之冷熱水比例與水量，最後換算各分區單位面積之溫泉水量。本研究利用溫度法推估礁溪溫泉水量為7,728CMD，其中冷熱水量分別為5,733與1,995CMD，換算成百分比為74%與26%。溫泉資源最多的分區為湯圍1，熱水比例高達全區的46%，其次為遊客中心、太子與停車場深三個分區，而奇立丹淺、大忠路與新小深三個分區熱水混合量則偏低。 The hot spring amount of Jiao-Si is almost the assessment of its total amount. However, the resources of Jiao-Si don’t distribute evenly. It is unreasonable to proceed with total amount control measures in this area. According to the seasonal reports of Jiao-Si hot spring, this research is to estimate the distribution of Jiao-Si hot spring amount and divide this area into seven controlled sections by way of Thiessen’s Polygon Method. This research is to estimate the proportion of cold and hot water of each section by the temperature method and then translated into per unit volume of each section. This research shows that the amount of the Jiao-Si hot spring is 7,728CMD by way of the temperature method，including the 5,733CMD of cold water and 1,995CMD of hot water. The percentage of the cold and hot water are 74% and 26%. The largest section of the hot spring resource is located in Tang-Wei first station, whose percentage of hot water is almost to 46% per hot spring amount. Followed are three sections :Tourism Center, Tai-Zi, and Parking space. The Ji-Li-Dan, Da-Zhong road and Shin-Shou, whose amount are lower other stations.
