摘要

本研究選擇勝光地區火災跡地中人工林內兩種主要樹種台灣二葉松(Pinus taiwanensis)與栓皮櫟(Quercus variabilis Blume)，利用枝葉包法研究野外葉片分解及養分的動態變化，同時進行實驗室的試驗研究不同溫度、水分及土壤對栓皮櫟及台灣二葉松葉片分解之影響。結果顯示，樣區中所選取之三個樣點在土壤基本理化性質上有些許的差異，栓皮櫟分解速率快於台灣二葉松；埋入土壤後的分解速率則快於置於地表的處理方式；而實驗室的分解試驗則顯示，栓皮櫟與台灣二葉松在高溫、25%的水分之下分解速率較高。

This study was aimed to investigate the decompositions and nutrient dynamics of the leaves of cork oaks (Quercus variabililis Blume) and Taiwan red pines (Pinus taiwanenis Hayata) in a burned site using the litterbag method. The impacts of incubation temperature, soil moisture and type of leaves decomposition were simultaneously conducted in the laboratory. Soil physicochemical properties differed from the selected sites indicated that oak leaves decomposed rate was faster than that of pine leaves. Leaves decomposed quickly when samples buried in the soils. Laboratory incubation showed that high temperature and 25% of soil moisture enhanced decomposition rate of oak and pine leaves.
