中文摘要 | 本研究係針對國立中興大學實驗林管理處文山實驗林場之植物社會進行研究。本 林場中共調查到 248 種維管束植物,其中木本植物種類最多之科為茜草科、薔薇科 (均 12 種, 各佔 4.92)、 樟科 (10 種, 佔 4.10%)、 冬青科、大戟科及茶科 (均 6 種, 各佔 2.46%),顯示該林場之植群為臺灣典型的亞熱帶闊葉樹森林。地被植物則以蘭科、水龍骨科 及鱗毛蕨科等之種類最多,其中蕨類植物多達 54 種,蕨類商數高達 6.969。生活型分析則 顯示喬木植物共 98 種,佔 50.2%,另藤本植物亦達 39 種, 佔 20.10%,顯示本地區極適 宜植物之生長。而在植群之定量分析上,上層之優勢樹種有豬腳楠、山紅柿、大頭茶等;地 被層之優勢植物則以鬼桫欏、琉球雞屎樹、月桃、鯽魚膽及觀音座蓮為主。在冠層中佔優勢 的江某、豬腳楠、樹杞、山紅柿、臺灣樹參、墨點櫻桃等種類,在地被層中亦有相當重要的 地位,顯示這些種類均能更新良好,將在未來演替過程中持續保有其重要性。本區植物社會 之種歧異度極高,新浦森岐異度指數在 0.90 以上,亦顯示本區植物社會之穩定性極高。 |
英文摘要 | The purpose of this study is to investigate and analyze the vegetation of the Wenshan Experiment Forest Station, NCHU. Totally 95 families, 248 species were recorded. Rubiaceae and Rosaceae(both contained 12 species and 4.92% respectively)are the largest families of wood plants at studied area. The other main families in consequence are Lauraceae(10 species, occupies 4.10%) , Aquifoliaceae, Euphorbiaceae, theaceae(6 species and 2.46% respectively). This fact reveals the plant constitution of studies area is a typical subtropical broad-leafed forest of Taiwan. The dominanace species of understory are mainly belong to the family Orchidaceae, Polypodiaceae, Dryopteridaceae. There are 54 fern species totally, and the pteridophyte-quotient is 6.96. The analysis of life-form of vascular plants reveals that phanerophytes and liana are 98 and 39 species, occupies 50.2% and 20.10% respectively, revealing that the environmental are suitable for the growth of plants. According to the results of quantitative vegetation analysis, the dominance species of overstory are Machilus thunbergii, Dospyros morrisiana, Schefflera octophylla, Gordonia axillaris, Ardisia sieboldii etc., and the dominance species of understory are Alsophila podophylla, Lasianthus fordii, Alpinia speciosa, Maesa tenera, Angiopteris lygodiifolia etc. The Simpson's index of species diversity of the studied area are avove 0.90, indicating that it is a stable plant community. |
