中文摘要 | 本研究探討插天山自然保留區中,臺灣山毛櫸之族群組成。結果顯示臺灣山毛櫸 林主要之共生優勢種有高山新木薑子、臺灣杜鵑、錐果櫟、紅淡比、白花八角、鐵杉、厚葉 柃木等樹種,其組成與歐美地區最大之區別為闊葉樹種極為豐富,而缺乏雲杉屬及冷杉屬之 種類。目前臺灣山毛櫸以小徑木佔大多數,但幼苗不多,僅發生於鬱閉破裂之處,加上結實 不佳,若未能重視其更新,其族群可能持續萎縮。而在坡向上,臺灣山毛櫸於北向區域之重 要值較高,同時在海拔分布上約以 1,500 ∼ 1,700m 為其最適界。 |
英文摘要 | The population constitution of Taiwan beech (Fagus hayatae Palib. ex Hay.) of Chatienshan Nature Reserve was studies. The main co-dominant species of Fagus hayatae are Neolitsea acuminatissima, Rhododendron formosanum, Cyclobalanopsis longinux, Cleyera japonica, Illicium philippinense, Tsuga chinensis, Eurya glaberrima, etc. Although Fagus hayatae persists its dominance, and the most individuals are saplings, due to the difficulty of regeneration and the absence of seedlings, Taiwan beech forest would be decreases soon, if we don't care its management. The habitable aspect of Fagus hayatae is north slopes, and the most suitable altitude is among 1,500 to 1,700m. |
