中文摘要 | 本研究探討臺灣中部中高海拔山區玉山國公園境內塔塔加地區(海拔高約2,600公尺)之四種植群下之鳥類群聚特徵,於1997年7-8月間利用圓圈法調查草原、松林、混合針葉林和雲杉林內之鳥類密度和組成。結果顯示本區約有30種鳥類,以雲杉林24種最多,混合針葉林18種,松林15種,草原僅10種,各植群內之鳥類組成均有其特色,隨著演替之進行,鳥類種數、總密度有增加之趨勢,種多樣性亦以雲杉林最高,草原最低,均勻度則以草原和松林較高。相似性指標顯示松林和混合針葉林相似程度最高,而演替階段越近之植群,鳥類群聚之相似性亦較高。臺灣中部中高海拔山區鳥類之群聚組成與分布,大多與當地植群帶之分布和鳥類攝食方式有密切之關係。 |
英文摘要 | The bird communities of four high elevation plant communities were studied at Tatachia, Yushan National Park, Taiwan. The plant communities included a mature primary spruce forest and three seral stages of secondary vegetation that grow after a fire, grassland, pine woodland and mixed coniferous forest. The densities of all 30 bird species found in the four plant communities were estimated by the circular-plot method in July and August, 1990. Each community at different sites shows distinct pattern in species composition, guild structure and bird density. Most species show preference in habitat selection. The avian community parameters roughly followed the succession pattern. Total number of species and total density increase along the succession gradient. The bird community in spruce forest had the highest Shannon diversity index, followed by pine woodland, mixed coniferous forest, and grassland. Evenness indices were highest in pine woodland and grassland, and lowest in mixed coniferous forest and spruce forest. The Bray-Curtis index of similarity between two bird communities decreased as the successional difference between plant communities increased. The bird communities in pine woodland and mixed coniferous forest, intermediate successional stages, had the highest index of similarity (0.55), while the bird communities, grassland and spruce forest, the extreme ends of pyrosere, were least similar (0.25). In this study habitat selection by birds was largely a function of habitat structure and bird foraging methods. |
