中文摘要 | 自1998年9月至1999年8月利用收集網及枝葉袋探討南投縣惠蓀實驗林場中相鄰的三種不同林分(天然闊葉林、次生闊葉林、杉木人工林)知枯枝落葉量的季節性變化與其分解速率。結果顯示杉木人工林枯枝落葉量在季節上有顯著的變異,僅在10月份(262.1g/m��/mo)顯著高於另二林分,及6月份高於次生闊葉林,其餘皆遠低於另二林分,枯枝落葉量在0.8-262.1 g/m��/mo之間;次生闊葉林的枯枝落葉量除了10, 5,6,8月份高於天然闊葉林以外,其餘時間都低於天然闊葉林,期量在14.3-160.3 g/m��/mo之間;而天然闊葉林枯枝落葉量在27.1-86.4g/m��/mo之間較為穩定。若以整年枯枝落葉總量計算,則以天然闊葉林6,782.6kg/ha/yr最高,次生闊葉林6,658.8 kg/ha/yr次之,杉木人工林4,512.6 kg/ha/yr最低。枝葉層的分解速率,在試驗初期(1998/10-1998/12)以天然闊葉林最快,次生闊葉林次之,杉木人工林最慢,其中杉木人工林再2個月時重量反而有增無減,及為反常,但在8個月後杉木人工林枝葉層分解速率加快,超過其他二種林分。 |
英文摘要 | The amount of litterfall and litter layer's decomposition rate of three different stands (namely, natural hardwood stand, NS; secondary hardwood stand, SS; and China-fir plantation stand, CPS) in the Hui-Sun Experimental Forest were monitored from Sept. 1988 to Aug. 1999 by using littertrap and litterbag approaches, respectively. The results showed that the lotterfall of CPS (0.8-262.1 g/m��/mo) varied significantly with season. Except in October (which amount to 262.1 g/m��/mo) and in June the litterfall of CPS was, in general, significantly lower than that of NS and SS through out the year. In October, however, it was higher than both NS and SS whereas in June it was higher than SS but lower than NS. During the study period the amount of litterfall of SS (14.3-160.3 g/m��/mo) was lower than that of NS except for the months of October, May, June and August. The litterfall collected from NS varied from 27.1 to 86.4 g/m��/mo and ws relatively stable. When estimated on yearly basis the amount of litterfall of NS (6,782.6 kg/ha/yr) was the highest followes by SS (6,658 kg/ha/yr) CPS which amounts to 4,512.6 kg/ha/yr was the lowest. With respeact to the decomposition litter collected from NS showed the highest rate during the initial stage (1998/10-1998/12) which was followed by that collected from SS and CPS. A rather unusual result was oberved for the decomposition of litter collected from CPS at 2 its rate accelerated and was higher than that of litter samples collected from NS and SS. |
