中文摘要 | 本研究以南投縣惠蓀林場關刀溪生態系相鄰的三種不同林型(林、次生林、杉木林)為調查試區,自1988年9月至1999年8月利用收集網收集枯落物,探討枯落物養分濃度與迴歸量之季節性變化。三種林分枯落物碳濃度平均在40.27~43.07%,氮濃度在0.86~2.29%,磷濃度在0.06~0.26%,鉀濃度在0.47~1.31%,鈣濃度在0.25~1.00%,鎂濃度在0.18~0.27%間。全年枯落物養分迴歸量碳為1.93~2.88t/ha;氮為41.48~104.30 kg/ha,磷為3.40~8.93 kg/ha;鉀為21.36~66.55 kg/ha;鈣為20.89~61.45 kg/ha;鎂為9.02~18.04 kg/ha。枯落物養分迴歸量以天然闊葉林最多,次生闊葉次之,杉木工人林最少。 |
英文摘要 | The seasonal variation of litterfall nutrient concentration and nutrient recycled amount of three different stands (natural hardwood, NS: secondary hardwood, SS; and China-fir plantation, CPS) in the Hui-Sun Experimental forest were monitored monthly by using littertrap approach from September 1988 to August 1999. During the investigation period, the litterfall nutrient concentration of carbon was 40-27-43.07%. motrpgem 0.86-2.29%, phosphorus 0.06-0.26%, potassium 0.47-1.31%, calcium 0.25-1.00, and magnesium 0.81-2027%. Annual amounts of these recycled nutrients in litterfall were 1.93-2.88 t/ha C, 41.48-104.30 kg/ha N, 3.40-8.93 kg/ha P, 21.36-66.55 kg/ha K, 20.99-61.45 kg/ha Ca, and 9.02-18.04 kg/ha Mg. Total annual nutrient input from litterfall were NS>SS>CPS. |
