中文摘要 | 本研究蒐集塔塔加雲杉林、鐵杉林、草原區(玉山箭竹及高山萱草)等三個永久樣區,深度各為0.05m及0.1m之土壤溫度以及埋設深度為0.05m之土壤熱流量觀測資料,應用傅立葉定律方程式推估三處永久樣區之土壤熱傳導係數,計算結果分別為雲杉林:1.160Jm-1℃-1S-1、鐵杉林:1.560Jm-1℃-1S-1、草原區:1.593Jm-1℃-1S-1;較之國外著名學者推算土壤熱傳導係數介於0.17~18.20Jm-1℃-1S-1,本研究之推算結果與之相較尚稱符合。 |
英文摘要 | In three permanent plots of Tatachia, spruce forest (Picea morrisonicola), hemlock forest (Tsuga chinensis) and grassland, we measured soil temperature at soil depths of 0.05 and 0.1m, and collected data of thermal flow at soil depth of 0.05m. Estimations using Fourier's law equation found that soil thermal conductivity in three permanent plots was 1.160Jm-1℃-1S-1 in spruce forest, 1.560Jm-1℃-1S-1 in hemlock forest and 1.593 Jm-1℃-1S-1 in grassland. These values were close to those (0.17~18.20 Jm-1℃-1S-1) found from other studies. |
