本研究自2009年起至2012監測林業試驗所蓮華池研究中心三號試驗集水區濱水帶之大氣溫度、溪流水溫以及表土5，30與50公分處的溫度。獲知試驗期間該濱水帶之大氣溫度、溪流水及土壤5、30、及50 cm深處之年均溫度分別為19.9、19.2、20.3、20.5及20.8℃。全年度溫度的變化幅度由大至小依次為：大氣、5 cm深土溫、30 cm深土溫、50 cm深土溫、溪流水溫，且均呈顯著的變化。大氣溫度的日變化最為顯著，表土5 cm深的土壤溫度次之，而50 cm深以下的土壤溫度的日變化最大幅度僅0.3℃，顯示深層土壤溫度幾乎無顯著日變化。本報告亦建立溪流水溫及表層5 cm土壤溫度與大氣溫度的相關回歸方程式。

This study recorded air, top soil layers and streamflow temperatures at the Lienhuachih No. 3 experimental watershed of the Lienhuachih Experimental Forest of the Taiwan Forestry Research Institute (TFRI) from 2009 to 2012. The results show that the average yearly temperatures for air, streamflow, the 5 cm soil layer, 30 cm soil layer and 50 cm soil layer during the monitoring period were: 19.9, 19.2, 20.3, 20.5 and 20.8℃, respectively. The yearly temperature changes were significant for all monitoring items and ranked in the following order: air, the 5 cm soil layer, 30 cm soil layer, 50 cm soil layer and streamflow. Air temperature had the maximum magnitude of changes within a day for all months, followed by the 5 cm top soil layer. However the maximum magnitudes of daily changes were less than 0.3℃ for soil layers deeper than 50 cm. The linear regression relationships of air temperature versus streamflow temperature and air temperature versus the temperature of the 5 cm top soil layer were also established in this report.
