The purpose of this study was to estimate the soil and litter layer nutrient contents in three stands (natural hardwood, NS; secondary hardwood, SS; and China-fir plantation, CPS) at Hue-Sun forest station. Litter layer (L、F、H) and soil in different layer

本研究目的在估算惠蓀林場三種林分(天然闊葉林,次生闊葉林,杉木人工林)的土壤化學性質與養分聚積量,每兩個月分別取枝葉層(L、F、H層)與土壤層(0?5, 5?10, 10?15, 15?20, 20?25 cm)進行養分濃度分析。結果顯示枝葉層養分含量除了鎂含量以次生闊葉林最高外,其餘養分都是天然闊葉林高於次生闊葉林、杉木人工林,其養分含量分別為碳7.73?24.57 t/ha;氮為352.0?1,312.3 kg/ha;磷為51.0?262.6 kg/ha;鉀為289.7?1,736.0 kg/ha;鈣
