中文摘要 | 臺灣油杉為政府公告之珍貴稀有樹種,侷限分佈於臺灣南北兩端。本研究調查臺 北坪林臺灣油杉生育地環境因子(包括海拔、坡度、方位角、全光天空域、土壤含水率及土 壤 pH 等)及植物社會。植群分類的結果顯示出臺灣油杉並非存在於均值性的植物社會中。 臺灣油杉小苗出現與否, 在海拔高和土壞 pH 值間有顯著性差異( 506m vs. 412m,p=0.0094; 4.08 vs. 4.39, p=0.0068 ),且植物社會組成亦有不同。 有小苗的樣區 多位於 DCA 軸的中間範圍。 |
英文摘要 | Keteleeria davidiana var. formosana is a rare species endemic to Taiwan . Its distribution is narrowly limited to two localities at low altitude of the island. Ping-Lin is in the extreme northern part, ca. 400 km away from the another habitat at the southern end. At Ping-Lin environmental factors (e.g. altitude, slope, aspect, whole light sky space, soil moisture, soil pH-value etc.) and plant species were investigated in 18 sampled quadrats (10* 10m �� ) within an area of ca. 3*3 km ��. The results of plant community analysis reveal diversities in the secondary forests of 183 vascular plants. The quadrats with saplings of the keteleeria species are significantly different from those quadrats without saplings in environmental factors such as altitude (506m vs. 412m) and A-layer soil pH-value (4.08 vs. 4.39), as well as in phytosociological classification. The quadrats with saplings of the Keteleeria species anchor in the middle levels of the DCA Axis. |
