摘要

行政院原住民委員會（簡稱原民會）自1998～2001年完成150處原住民居住潛在危險部落調査，本研究乃針對150處潛在危險山地部落中抽樣21處進行實地潛在危險地區之GPS定位與現況調查，經調査結果獲知，該21處抽樣調査村落中之47處災害樣本點，其地理位置雖遍佈台灣全島，但其潛在災害特性多以崩塌與土石流等災害類型為主，且多位於舊崩塌地及嚴重坡面沖蝕區，本文同時以2002年水土保持技術規範所訂定之山坡地環境風險率評估方法，分析各部落中之潛在災害環境敏感度，進而判定各潛在災害環境敏感區，以期提供作為原住民居住環境風險管理與其土砂災害防治方案研擬之參考。

150 spots of potential sediment disasters occurred in aboriginal tribes area. It have been paid attention by Aboriginal Committee since 1998, Twenty-one spots were selected among 150 potentially dangerous sites for this study, Environmental geological investigations and geomophological characteristics determinations were also required during the period of this research. All results can be displayed as different types of potential disasters induced by landslide, debris flow and soil mass movement all over the mountainous region habilitated by aboriginal people. Each class of environmental sensitive factors and environmental risk probability was calculated by means of Soil and Water conservation Technical Code announced in 2002. This research can be expected to offer a reference for the environmental risk analysis regarding to the disaster prevention program proposed by the Aboriginal Committee in Taiwan. This program can help aboriginal tribes escape from the potential environmental hazard in the future.
