臺灣原住民社區聚落地大多坐落在山間水畔。因地理位置和孤立性的緣由，使天然災害好發於原民社區。當災害在原民部落發生時，往往無法立即得到外來的援助。雖大多數的部落社區保有傳統階級制度，但在災害發生時卻是沒有建立現代社會組織的指揮系統去應對。在這種情況下，本研究想要了解指揮系統是否會影響部落防災與災難應變組織工作的建置。
本研究採文獻探討及深度訪談法，彙整國內外災防體制、地方防災應變及原住民族階級制度相關文獻，研究者以立意取樣(purposive sampling)及滾雪球(Snowball sampling)方式，至臺東縣長濱鄉長光部落進行田野觀察。並由夥伴引薦長光部落居民進行深度訪談(qualitative interviews)。
經由前述研究，可以歸納成三個研究結論：一、因為長光部落未有「防救災工作組織」，所以防救災工作的執行是透過部落領導者的指示下進行；二、部落組織在傳統祭典儀式中仍持續運作，將災防觀念導入部落組織，使部落自主防災有建置的可能性；三、強化部落防災應變，從部落領導階級做起。綜合前述三項發現可得知，部落雖無防災社區組織編制，但其文化已具有領導者及各階級的組織作業方式。
本研究可做為未來國內規劃對阿美族及其他原住民族部落防災或救災工作，提供一個提昇防救災成效的重要參考文獻。

The communities of the indigenous population in Taiwan are usually surrounded by mountains and closed to rivers. Because of their geographic position and isolation, natural disasters usually occur in indigenous communities. When disasters happened in indigenous tribes, residents could not immediately get help from outside, they do not response without establishing the modern command system when disasters is happening. In this situation, the aim is to understand whether the command system affects the establishment tribal disaster prevention and disaster response organization or not.
The methods in this study were literature review and qualitative interviews to aggregate domestic and international disaster prevention system, local disaster prevention strain and indigenous literature class system. The researchers used Purposive sampling and Snowball sampling to execute field at the Changguang tribe in Taitung. At the same time, the researchers had qualitative interviews with residents who were introduced by our partners.
According to the previous studies, our findings could summarize in three conclusions. First, there were no disaster prevention and response organization in the Changguang tribe, so the disaster prevention and response action were executed through instructions from the leader of the community. Second, the traditional festival has been ongoing in the community so far. It is possible that we could put the concept into their organization and promote them to establish disaster prevention and response spontaneously. Third, To strengthen the disaster prevention and response in tribes, it could begin from the leadership. Although there is no establishment of disaster-resistant community in the tribe, the leaders and hierarchy have early existed in the tribe.
This study could be an important reference which promoted the efficiency of disaster prevention and rescue, to plan the job of disaster-resistance or rescue in Amis and other indigenous populations in the future.
