中文摘要 | 本研究目的為測定自然環境光合作用速率推估闊葉林淨生產力。試驗樹種選取具代表福山植物園之厚殼桂(”Cryptocarya chinensis”)。樹冠層淨光合作用速率隨著樹冠高層到低層順序遞減。以淨光合作用速率計算厚殼桂11個月晝間每單位葉面積可以固定3,906 g CO_2 m^(-2)。11個月蒸散量每單位葉面積可以蒸散508 kg H_2O m^(-2)。此一結果將提供臺灣闊葉樹碳吸存計算之基本參數。 |
英文摘要 | The purpose of this study is to estimate net primary production of deciduous broad-leaved forest by measuring photosynthesis rate measurement in the natural environment. ”Cryptocarya chinensis” is chosen as study subject in Fu-Shan botanic garden. The net photosynthesis rate is found decreased by canopy degrees. ”Cryptocarya chinensis” is able to sequestrate 3,906 g m^(-2) CO_2 and to transpirate 508 kg m^(-2) H_2O that was measured by net photosynthesis rate and transpiration rate in eleven months. The result has supplied a fundamental parameter for carbon sequestration calculation of broad-leaved forest. |
