中文摘要 | 本文根據125個樣區資料,利用降趨對應分析法(detrended correspondence analysis,簡稱DCA)分析,並與七個環境因子:海拔高、含石率、 坡度、地形、方位、全天光空域及直射光空域做相關檢驗,結果顯示第一軸與海 拔高及含石率相關性顯著,第二軸與坡度及地形之相關性顯著,故本區之植物社 會得以第一、二軸來解釋,各樣區於第一、二軸平面之分布序列示於圖一,依其 優勢組成之不同可分為五型:I.玉山箭竹型、II.玉山箭竹-杜鵑-玉山圓柏型、III. 玉山圓柏型、IV.羊茅型、V.高山柳型,及6亞型、:III-1 奇萊烏頭-小穎溝稃草 亞型、III-2 玉山小蘗亞型、IV-1 南湖柳葉菜亞型、IV-2 尼泊爾籟簫-雪山翻白 草亞型、IV-3 羊茅-玉山山蘿蔔亞型、IV-4 艾亞型等,與前人研究者大多楔合而 有部分不同。維管束植物種數包括變種在內總計為167種,其中屬於臺灣特產 者,計104種佔本區維管束植物種數之62%(表四)。 |
英文摘要 | Detrended Correspondence Analysis (DCA) was used to analyze the data obtained from 125 quadrates at Nanhutashan. The correlation of environmental factors and ordination axes were tested. The results indicate that the first axis is significantly correlated to elevation and stoniness of soil, and the second axis significantyly correlated to slope and topography. Based on the composition of dominant species, communities at Nanhutashan were mainly classified into 5 types :I. Yushania niitakayamensis type, II. Yushania niitakayamensis-Rhododendron sp.-Juniperus squamata var. morrisonicola type, III. Juniperus squamata var. morrisonicola type, IV. Festuca ovina type, and V. Salix taiwanalpina type. Total vascular-plant taxa found at Nanhutashan were 167, of which 104 (62% of the total species) are endemic. |
