崁津部落位於桃園市大漢溪畔，所在位置屬行水區而具洪患風險。近年，公部門對部落與周遭進行各種建設與政策等治理手段；然而，理解居民臨災時的資訊傳遞方式及其如何影響避難行為，才能根本性地降低居民的受災風險。本研究以半結構式深度訪談蒐集資料，探討居民災時傳遞災害資訊的方式及其與避難決策的關係。研究發現，1996年賀伯颱風除造成部落淹水，也促使部落的災害訊息傳遞方式從社區內部以文化為基礎的雙向溝通，轉變為由外部連結式網絡主導的單向傳遞；而避難行為也從居民共識之集體行動，漸漸演化質變成為確保安居的權衡決策。本研究建議公部門於平時增加與部落的風險溝通，以延續居民自發性正確避難的正向回饋。

The Pamatangan, an Amis indigenous tribe, faces flood risk as it is located on the Da-an riverbank in Taoyuan City. Over the last decade, the government has gradually built hardware construction and applied a flood management strategy to mitigate flood risk. Understanding residents' disaster information transmission and evacuation decision-making process could fundamentally reduce their disaster exposure. Semi-structured interviews were conducted to explore the relationship between residents' disaster information transmission and their evacuation decision-making process. The results showed that Typhoon Herb caused local floods and transformed information transmission from "culture-based reciprocal communal communication" to "command-oriented unilateral order beyond community". Further, residents’ evacuation behavior transitioned from "consensus-based collective action" to "obedience to command for the right of abode". Consequently, increasing positive risk communication between the public sector and the tribe and bolstering consensus within the tribe to foster residents' autonomous evacuation decision-making would ensure sustainability.
