中文摘要 | 本研究係針對國立臺灣大學農學院實驗林溪頭營林區中之鳳凰山地后天然林進行調查分析,研究樣區海拔高度自1,650~1,700m,面積0.45ha,其中劃分為45個小區。目的在於分析其林分組成、物種之族群結構,同時識別不同發育階段之塊集,以了解其植群動態與更新狀況。結果顯示,出現178種植物,分屬於72科128屬;重要樹種為南投木薑子、紅花八角、變葉新木薑子、長尾柯和薯豆等,且幾乎都出現萌蘗現象,藉以幫助更新。以卡方測驗檢定,出現萌蘗現象的17種植物中,以山香圓、黃杞、長葉木薑子、瓊楠、紅楠、大葉柯和變葉新木薑子等種類之萌蘗性與徑級與徑級大小有關聯。優勢樹種之徑級結構圖,主要為反J型。枯立木以小徑木為主,枯倒木則以大徑級為主。 |
英文摘要 | The aims of this study are to analyze the stand composition, population structure, to know the patch dynamic within different growing stages, and to understand the vegetation dynamics and regeneration of natural forests which were located on Fenghuang mountains, Chitou area, Lu-ku, Nantou county, a part of Experimental Forests of National Taiwan University. A total of 45 plots were set up in this study area, which covered about 0.45 ha, and its elevation ranges from 1,650- 1,700 meters above sea level. A total of 178 species in 128 genera and 72 families were collected in this study area, among them, Litsea acuminate, Illicium arborescens, Neolitsea aciculate var. variablillima, Castanopsis cuspidate var. carlesii, Elaeocarpus japonicus etc. were dominant species, and almost all of them sprouted for regeneration. The sproutings of 17 species was often correlated with their diameter size. Population structure of main species in this study area was almost inverse J-shape. |
