[ 摘要 ]

本研究紀錄屏東縣霧台鄉魯凱族的民族植物，蕨類、雙子葉植物、單子葉植物，有用途植物245種。植物利用分為食用、藥用、纖維、建材、薪材、用具、童玩、經濟、裝飾、文化、飼料、肥料、其它等13個用途類別項目。其中藥用植物除了拉丁學名、中文名，也紀錄其魯凱母語名。各用途類別之利用種數中，以食用植物所佔種類最多，其次依序是用具、裝飾、藥用、經濟、飼料、文化、薪材、建材、童玩、其他、纖維、肥料。採用歧異度指數評估有用途的植物，得屏東縣霧台鄉魯凱族的民族植物Shannon氏歧異度指數為2.27，且利用稀釋法程式算出期望的物種數，並繪出稀釋曲線圖。

The research has listed 245 species of plants ( Pteridophyte, Dicotyledon, and Monocotyledon ) among the Ethnobotany of Wutai Rukai tribe in Pingtung County being utilized for living.

In the category of medicine, in addition to the scientific names and the Chinese names, the local tribe''''''''''''''''s ( Rukai ) names have been stated in this research. Among these categories, the plants for foodstuffs take the most amount that is up to 94, and then the rest come in order utensils, decorations, medicines, commercial use, livestock feeds, cultural use, firewood, building materials, children''''''''''''''''s traditional toys, miscellaneous use, threads, and fertilizers. Shannon''''''''''''''''s index of diversity was used to evaluate this research, and the result of which is 2.27. Moreover, the Kreb''''''''''''''''s Ecological methodology program was used to calculate the expected number of species and to figure the rarefaction curve.
