光榮部落是位於花蓮縣壽豐鄉的南勢阿美族部落，本研究透過庭園植物普查與關鍵報導人推薦法進行住戶訪談瞭解庭園植物多樣性現況，及其在物種保育上的貢獻。
研究結果顯示：133戶擁有庭園植物共101科269屬346種，以植物生活型和種源來看，分別為草本和栽培種佔優勢；最常見的庭園植物為山苦瓜（68％）、台灣山蘇花（65％）、檳榔（58％）、葡萄（57％）、芋（52％）、矮仙丹（50％）等，庭園常見的10種喬木、草本、藤本以食用為主，而常見的10種灌木則以觀賞為主；庭園可區分為蔬菜型庭園、果樹型庭園、觀賞型庭園與混合型庭園等，皆呈現出南國風情的農村景觀；庭園面積與庭園植物種數，以及庭園水泥化與庭園植物種數間皆有顯著相關；庭園植物調查最少抽樣住戶數達36戶（16％）即可瞭解當地庭園植物多樣性。
庭園植物用途以觀賞最多（171種），其次依序為食用（131種）、多用途（47種）、藥用（32種）、生活用（6種）、祭祀文化（4種），其中多用途植物以檳榔、苦楝、山棕與紫薇等用途多樣性最高。
光榮部落庭園植物提供食物補給，同時亦具植物文化、物種與遺傳多樣性等保育的價值：如檳榔、麵包樹、番龍眼、毛柿、台灣火刺木、宜梧、菝契、筆筒樹、台灣山蘇、黃麻嬰、兔兒菜、黃鵪菜、龍葵、山苦瓜、紫背草、過溝菜蕨、山萵苣、南瓜、木鱉子、佛手瓜、黃藤、林投、月桃、杜虹、山棕、刺莧、腎蕨、荖藤、樹豆、花生、萊豆、鵲豆、翼豆、豇豆、楊桃、龍眼、木瓜、柚子、芒果、香蕉、蓮霧、辣椒、食茱萸、薑、蕗蕎、韭菜、蒜等皆為阿美族傳統野蔬果、水果或調味料植物等，不但具有植物文化保存的意義，而且提供物種多樣性保存的價值，另外，花生與豇豆等有別於一般常見的品種，亦具有遺傳多樣性保存的價值。

Guang Rung is a village of Nan Shr A’mis. The purpose of this study is to understand homegarden plants diversity and conservation value. In this study, 133 households were investigated. There are 346 species belonging to 269 genera and 101 families of homegarden plants. Herbaceouses are the most for their life form. Most of the homegarden plants originated in cultivated plants. Then, the most frequent homegarden plants are Momordica charantia var. abbreviate(68％)、Asplenium nidus(65％)、Areca catechu(58％)、Vitis vinifera(57％)、Colocasia esculenta(52％)、Ixora williamsii cv. Sunkist(50％). The majority of the top ten trees, herbaceouses and vines were used in edible, but the top ten shrubs were almost used as ornamental. The homegarden may differentiate from the vegetables homegarden, the fruit tree homegarden, the ornamental homegarden and the mixed type homegarden, all presents the countryside landscape of austral-tropical style. The homegarden area and the homegarden cement area, as well as the homegarden plant diversity to have reveals the correlation. The homegarden plants investigation and analysis show the minimum sampling amounts to 36 households (16%), then to understand the homegarden plant diversity.
The homegarden plant use contains ornamental (171), edible (131), multi-use (47), medicinal (32), the life uses (6), the sacred culture (4).
Some homegarden plants are A’mis traditional wild edible plants, and have the conservation value of A’mis culture and species diversity. They are Areca catechu, Artocarpus incisus, Pometia pinnata, Diospyros discolor, Pyracantha koidzumii, Elaeagnus oldhamii, Smilax china, Sphaeropteris lepifera, Asplenium nidus, Ixeris chinensis, Youngia japonica, Solanum nigrum, Zanthoxylum ailanthoides, Momordica charantia var. abbreviata, Emilia sonchifolia, Anisogonium esculentum, Lactuca sororia, Cucurbita moschata, Momordica cochinchinensis, Sechium edule, Calamus quiquesetinervius, Pandanus odoratissimus, Alpinia speciosa, Callicarpa formosana, Arenga engleri, Amaranthus spinosus, Nephrolepis auriculata, Piper betle, Cajanus cajan, Arachis hypogaea, Phaseolus limensis, Lablab purpurea, Psophocarpus tetragonolobus, Vigna sesquipedalis, Averrhoa carambola, Euphoria longana, Carica papaya, Citrus grandis, Mangifera indica, Musa sapientum, Syzygium samarangense, Capsicum annum, Zanthoxylum ailanthoides, Zingiber officinal, Allium bakeri, Allium odorum, Allium sativum. Among these plants, some cultivars are different from common strains, e.g. one of the Arachis hypogaea and one of the Vigna sesquipedalis, which provide the conservation value of genetic diversity.
