台灣近42萬公頃人工林中超過22萬公頃為針葉林,本計畫分期調查中央山脈不同海拔之代表針葉林大型真菌子實體,並予鑑定,希望達成以下目的:(1) 建立永久樣區;(2) 發展針葉林真菌多樣性與種群結構調查方法;(3) 了解各種真菌出菇季節;(4) 比較人工針葉林與鄰近原生林之真菌多樣性與種群結構;(5) 測定環境因子與植被對真菌豐富度的影響。本年度以穿越線橫截樣區,調查阿里山針葉林生態系的紅檜、柳杉與台灣杉林中,大型真菌的出菇種類與出菇量:共計27科164種2,922個子實體,其中擔子菌156種;子囊菌7種。營養功能群區分,有150種腐生菌,以簇生沿絲傘(Naematoloma fasciculare)分布最為普遍,另外14種屬植物共生菌,呈現阿里山區針葉林蘊藏豐富的真菌資源。本結果並與由林務局所補助巒大事業區柳杉林研究區的真菌多樣性調查結果比較。 There are near 420,000 ha planted forest in Taiwan, and the planted coniferous forests are more than 220,000 ha. Propose of this study is to investigate and identify macrofungi in the planted coniferous forests of the Central Mountains at different elevations. We hope to achieve following goals: (1) to establish permanent plots; (2) to develop methodologies for assessing diversity and fungal community structure in the coniferous forest; (3) to understand the fungi fruit seasons; (4) to compare the mycodiversity and community composition between planted coniferous forest and neighbor natural forest; (5) to determine whether fungal species richness is influenced by environmental or botanic factors. This year, we investigated macrofungi in the Cryptomeria japonica plantations, Chamaecyparis formosensis plantations, and the Taiwania cryptomerioides plantations of Ali Mountain. The fruiting body survey was conducted with the transect line in the forests. There were 2,922 fruiting bodies of 164 species belonged to 27 families were recorded in this year, including 156 basidiomycetes, 7 ascomycetes and a slime mold. There were 150 saprobes and 14 ectomycorrhizal fungi, Naematoloma fasciculare was the dominant species. This result was compared with the fungal diversity in the Cryptomeria japonica plantation at Luan-Da working circle that work was supported by Forest Bureau.
