原住民族對於神話的觀念與已然遠離部落、擁有綿長文字與文獻歷史的民族如漢族有極大的差異。部落人認為神話的真實性、神聖性與可以實踐的程度很高，它們不僅是口頭的或文字上的散體敘述，也跟部落的現實生活有直接而密切的關聯。基於這樣的理解，於是嘗試跨越不同學派的理論與方法，以民族整體的神話作為分析的對象，以「樹」的概念安置每一個神話主題、情節，觀察其形態，嘗試理解族群或部落如何看待、應用神話在儀式、觀念與禁忌等相互間有複雜牽涉的事項。神話以巨大的樹的形象由大地而向蒼穹伸展出巨幹與枝葉，樹身纏繞或依附的藤蔓或附生的植物，都可視為文化習俗對神話的交融纏繞。對於神話樹形象的擴張是由於站在神話的角度開啟視野，由文化的角度觀看，形象的大小可能逆轉；從另一種視野焦點鳥瞰，神話與習俗、禁忌、觀念、信仰、藝術等均可成為民族文化園地中的一棵樹，儘管已經不見相互依倚纏繞的親密，但是在園林中彼此倚靠的關係仍然存在。

The concept about myth of indigenous peoples has great differences from peoples, such as Han, which already away from tribes and has long-time characters and historical documents. Indigenous peoples believe the authenticity, sanctity of myth and its high practicality, and it's not only verbal or written prose narration but also with the direct and close relation to real tribal life. Based on this understanding, trying to cross different schools of theory and method and use whole national myth to be analytic object, arranging every thesis and motif by the concept of ＂tree,＂ and then observing its form and trying to understand how Indigenous peoples treat and apply issues complicated involved with ceremonies, ideas and taboos among myth. Mythology is seen as a giant tree, stretches out its great trunk and branches from earth to sky, and the winding tree trunks, attached vines or plants can be regarded as a symbol of mingling culture, customs and myth. The expansion of image of the myth tree is due to standing in mythic angle, but from the cultural point of view, size of this image may be reversed; from another sight, myths, customs, taboos, ideas, beliefs, arts and others may become one tree in cultural garden, although their depending intimacy is no longer seen, in the garden the relationship of mutually leaning still exists.
