近年來受到全球氣候變遷影響，臺灣氣候狀況具變異情況，季節乾溼特性加強使得降雨變異情況發生，極端降雨事件之衝擊促使山區地帶各式土砂災害。此外山區聚落交通不易且處於環境敏感帶，當極端降雨事件發生時，將導致聚落聯外道路受災害阻斷而形成災害孤島效應。為應對與調適此情況發生，須從理論至實務面進行分析探討，以因應孤島效應與極端降雨之發生及調適。因此本計畫擬先蒐集災害孤島案例與相關研究建構出災因指標，並依各類災害潛勢影響範圍，估算聯外道路阻斷機率以分析各聚落之孤島潛勢狀況。而後針對高潛勢聚落以時空序列方法進行複合式土砂災害風險評估，分析災害類型包括崩塌、土石流、河道沖淤及劇烈土砂運動所衍生之洪澇現象，並依評估結果檢討避難據點與物資站安全情況及物資儲量。最後規劃出適於當地聚落之軟硬體防災措施(如避難點規劃、避難決策與防災組織)，且透過實際訪查融入公眾意見資訊以提升孤島聚落韌性力以因應環境之脆弱性，並促成聚落與本計畫團隊達成共識，完整結合理論與實務防災規劃。冀望凝聚防災意識，引領在地防災組織發展，並培養成為自主性防災模範聚落。 Due to worldwide climate change, the frequency of critical rainfall events and rainfall distribution patterns in Taiwan have been changed, as the result, the occurrences of various sediment disasters also raise in mountain areas. This phenomenon causes serious damages especially in some mountain areas which have inconvenient traffic situation and sensitive environment regions, thus, these areas have higher potential to become isolated island where people cannot leave one place to the other through any transportation tools on the ground. In order to face and adapt isolated effect caused by critical rainfall events, this study collects all isolated effect related cases and constructs their disaster factors, then estimates the blocking probability of isolated island potential in each village based on access road in various disaster potential regions. This study focuses on high potential regions and evaluates multiple sediment disaster risks. Categories of sediment multi-hazard include landslide, debris flow, deposition and erosion of channel and even compound disaster (flood damage) caused by serious sediment movement. To design a multiple sediment disaster risk evaluation, the minimum stock in emergent shelters and the proper condition of themselves are necessary. Moreover, combine public participation advices and disaster prevention decisions in local areas to generate the consensus based on theoretical and practical conditions at the same time. At last, self-disaster prevention community construction can reduce the losses and upgrade capacity of resilience and adaption from vulnerability through growing up disaster prevention consensus and helping the development of local disaster prevention association.
