本文嘗試鉤畫出干闌構住家在臺灣原住民族中分布的範圍，進而探討提出其相互遷徙關係之假說。本文先條列既有的原住民干闌構建築調查與研究成果，再借用人類學者、先史學者、語言學者以及歷史學者對原住民之來源遷徙關連的研究成果，企圖建構其建築型態之間的可能傳播關係。在建構的過程中，本文有意矯正過去被誤認的原住民族群的建築型態；如過去被微妙地忽略的花東地區的阿美族建築，以及蘭嶼達悟族或是巴丹群島(Batanes)上的Ivatan 人的建築所具有的特性，分析其隱含的干闌構建築之特色。進而將北臺灣、蘭陽平原、花東地區及蘭嶼、巴丹群島之間的建築文化脈絡，依原住民的起源、遷徙的傳說，提出其間聯繫關係的假說。

This article tries to elucidate the relation of the distribution and diffusion of aborigines pile-dwelling (raised living ground floor which supported by piles) in Taiwan. Based on the materials from field survey contemporary and the historical records which Japanese anthropologists, especially architectural researchers investigated during the Japanese colonization period. In fact, we have been successful in deciphering the traits of traditional pile-dwellings of the Amis of eastern Taiwan, and the Tao on Lan Yuh island. Though it seemed that Japanese scholars never came to the conclusion that those residences being pile-dwelling. Concurrently, field surveying and literature analyzing tells that the residences of the Ivatan in Batanes, south of Lan Yuh, were transformed from pile-dwelling. Furthermore, those residences of the aborigines settled on Lan Yuh island, and in eastern, northeastern, and northern Taiwan also bear the characteristics of the pile-dwelling. Intriguingly, we find all the ancestors of the Ketagalan (in Taipei area, northern Taiwan), the Kavalan (in I Lan plain, northeastern Taiwan), and the Amis (in eastern Taiwan) immigrated northboundly from oversea via Sanasai (Lu island, next to Lan Yuh island), according to the Sanasai legend. Resultingly, the hypothesis that the diffusion of aborigines Pile-dwelling in northern and eastern Taiwan is in connection with the aborigines migration route can be established.
