本文皆在探討台灣北部羅培山山地雨林之森林結構及物種組成,於年起在海 拔1 , 136-1 , 164 m 處設立一公頃之永久樣臣,樣區內所有胸高直徑( dbh) 主cm 之木本 植物均加以標定、鑑別、度量及記錄。總共記錄12 , 934 株植物,分屬於70 分類群及料。植株數量最多之料為殼斗料、八角苗香料及茶料,總計為所有植株之5 l. 。依據 植株之總底面積之大小,優勢種分別為錐果機、紅楠、毯子機、紅花八角、山紅林及J呆在 樟o 雙向指標種分析法(TWINSPAN) 及降趨對應分析法DCA) 同時可將本樣區畫分 成二種林型,其分佈與坡向及暴露程度有密切相關。所區分出之林型以優勢種及特徵種 命名之,各為錐呆揀一大明橘~及紅花八角一小花鼠刺型。前者生長於稜脊及東北向坡 地,面對強烈東北季風吹襲;後者則分部於隱蔽之西南向坡地及溪谷。兩種林型不論在 結構及物種組成上均有明顯區別。樣臣中大部分的物種在徑級結構上多呈現反J- 型或 L型分佈,表示在樣區中均能維持良好之更新狀態。
The forest stmcture and woody species composition were investigated in a montane rainforest of Mt. Lopei in northern Taiwan. All stems?: I cm dbh were measured and identified for a permanent plot of I-ha (1 ,136 to 1,164 m as!.). Approximately 12,934 stems of70 taxa in 31 families were found. The most abundant families were Fagaceae, Illiciaceae, and Theaceae, representing 51.5% of the individuals. The dominant species, based on basal areas were Cyclobalanopsis /onginux, Machi/us thunbergii, Cyclobalanopsis sessilifolia, llliciulI1 arborescens, Diospyros morrisiana, and Meliosma seqimulata. Comparison of TWINSPAN groupings with the DCA ordination showed a definitive separation of forest types along a topographic gradient. The categorized forest types were the Cyclobalanopsis longinux-Myrsine seguinii type on the ridgetop and northeastern slope facing strong northeastern monsoon, and the Illicium arborescens-Itea parviflora type on the relatively protected southwestern slope. Evident differences of the composition and structure were observed between these two forest types. Size-class structures of most species showed an inverse J-shaped or an inverse L-shaped distribution, both indieators of a continuous recruitment in this permanent plot.
