中文摘要 | 本研究於2009至2010年調查墾丁國家公園陸域範圍內出現之歸化植物,分析不同棲地類型出現之歸化植物種類與頻度,並設置211個定量樣區計算原生植物及歸化植物的重要値,瞭解各類植物之優勢度。兩年期間共記錄到歸化植物41科96屬120種,種數最多的前3個科分別為菊科20種、豆科16種、禾本科12種。出現頻度最高者為大花咸豐草,次高者為銀合歡。在14類棲地類型中,以「道路邊」有最多的歸化植物種數,達108種,其次為「荒廢地」71種。歸化植物在墓地、公園綠地、廢耕地、道路邊、果園及農地等六類棲地類型的入侵情形最嚴重,樣區內歸化種重要値皆超過70%。然而,在樹冠鬱閉良好的天然林內並未出現歸化植物,顯示歸化植物在高光的環境較具競爭優勢。墾丁國家公園陸域範圍內有6種歸化植物為世界自然保育聯盟公告之「世界百大入侵種」,包括小花蔓澤蘭、馬櫻丹、銀合歡、香澤蘭、刺軸含羞木及南美蟛蜞菊,後3種目前在園區內的族群數量並不多,但仍須持續監控管理。 |
英文摘要 | This research investigated the species composition and frequency of naturalized plants found in various habitat types of Kenting National Park from 2009 to 2010. In addition, 211 plots were set up to quantify the importance values of native plants as well as those of naturalized plants. During the two years of our investigation, naturalized plants were recorded as belonging to 41 families, 96 genus, and 120 species, with the most abundant top three families to be Asteraceae (20 species), Fabaceae (16 species), and Poaceae (12 species). The most frequently occurred species was Bidens pilosa var. radiata, followed by Leucaena leucocephala. Among the 14 habitat types, ―roadside‖ was found to have the highest species richness of naturalized plants (108 species), followed by ―waste land‖ (71 species). In the aspect of invasiveness, the fol-lowing six habitat types, including cemetery, parks, cultivation abandoned land, road side, orchard, and farm land, all showed their importance values of naturalized plants to be more than 70%. No naturalized plants occurred in natural forest where the forest ca-nopy was closed. Evidently, naturalized plants possessed competitive advantage in high light environments. Six naturalied species, namely Mikania micrantha, Lantana camara, L. leucocephala, Chromolaena odorata, Mimosa pigra, and Sphagneticola trilobata,found in Kenting National Park are listed in ―100 of the world’s worst invasive alien species‖ announced by International Union for Conservation of Nature. The last three species did not have large population in the park yet, but continuous supervision is re-quired. |
