中文摘要 | 丹大地區為目前臺灣本島所劃設最大野生動物重要棲息環境,面積廣達近十一萬公頃,本區氣候涵蓋亞熱帶、暖溫帶及冷溫帶等三個氣候帶。本研究調查範圍乃以丹大溪及卡社溪集水區為主,針對區內第7~22林班及35~40林班之天然生原始林及次生林進行植群生態調查。總計設置76個10×25m長方形樣區(含8個永久樣區),調查其植群組成與林分構造。 植相調查共記錄維管束植物154科489屬858種,列為稀有者有33種,屬臺灣地區特有種者計196種,約佔全區植物種類之1/4。經矩陣群團分析之結果,可分為2個高山草原社會(A. 臺灣馬醉木-紅毛杜鵑-刺柏-臺灣二葉松群叢;B.高山芒-巒大蕨群叢)與16個森林植物社會:A臺灣冷杉-鐵杉林型(A1.臺灣冷杉-鐵杉亞型;A2.鐵杉-臺灣扁柏亞型);B.臺灣雲杉-臺灣扁柏林型;C.狹葉櫟-三鬥石櫟林型;D.香杉-山肉桂林型;E.臺灣鴨腳木-臺灣紅榨槭林型;F.假長葉楠-紅檜林型;G.長尾尖葉櫧林型(G1.西施花亞型;G2.長尾尖葉櫧-西施花亞型;G3.森氏櫟-高山新木薑子亞型);H.臺灣杜鵑林型;I.紅楠-杏葉石櫟-烏心石林型;J.青剛櫟-黃連木-臺灣櫸林型;K.相思樹林型;L.血桐-山黃麻林型;M.臺灣二葉松-臺灣赤楊林型;N.臺灣赤楊林型;O.化香樹林型;P.栓皮櫟林型。 為探討環境因子與植群分布之關係,本研究採用11項環境因子進行相關檢測,影響植群分布之環境因子包括海拔高、水分指數、全天光空域、土壤含水率、土壤pH值、坡向等。 |
英文摘要 | Dan-da region, the largest wildlife protection habitat in Taiwan, covers an area of 109,952 ha. Its climate includes to sub-tropic, warm-temperate and cool-temperate zones. The objectives of this study were to inventory plant species, perform vegetation analysis and set up permanent plots for future monitoring. This study established a total of 76 sample plots, including 8 permanent plots. The inventory of vascular plant found 154 families, 489 genera, 858 species among which 33 species are rare. According to the matrix cluster analysis (MCA), the vegetation can be classified into the following types: 2 montane grass types (Pinus taiwanensis-Pieris taiwanensis-Juniperus formosana var. formosansa-Rhododendron rubropilosum association, Miscanthus transmorrisonensis-Pteridium aquilinumn ssp. wightianum association) and 16 forest types: (A) Abies kawakamii-Tsuga chinensis type, (Al) Abies kawakamii-Tsuga chinensis subtype, (A2) Tsuga chinensis-Chamaecyparis obtusa var. formosana subtype, (B) Picea morrisonicola-Chamaecyparis obtusa var. formosana type, (C) Cyclobalanopsis stenophylloides-Pasania hancei type, (D) Cunninghamia lanceolata var. konishii-Cinnamomum insularimontanum type, (E) Schefflera taiwaniana-Acer morrisonense type, (F) Machilus japonica-Chamaecyparis formosensis type, (G) Castanopsis carlesii type, (G1) Rhododendron ellipticum subtype, (G2) Castanopsis calesii-Rhododendron ellipticum subtype, (G3) Cyclobalanopsis morii-Neolitsea accuminatissima subtype, (H) Rhododendron formosanum type, (I) Machilus thunbergii-Lithocarpus amygdalifolius-Michelia compressa type, (J) Cyclobalanopsis glauca-Pistacia chinensis-Zelkova serrata type, (K) Acacia confusa type, (L) Macaranga tanarius-Trema orientalis type, (M) Pinus taiwanensis-Alnus joponica type, (N) Alnus formosana type, (O) Platycarya strobilacea type, and (P) Quercus variab ilis type. To evaluate the effects of environment factors on vegetation, eleven environment factors were observed within all sampling stands. It was found that altitude, moisture index, whole light sky space, soil water, soil pH, and aspect were the most significant factors effecting the distribution of vegetation. |
