坡地防災及維生通道路網建置及致災潛勢劃定之研究

全球氣候變遷所導致的極端氣候，各種災害的發生強度及頻率愈來愈大、導致多處山區聚落及坡地社區因道路中斷而失去對外聯繫，搶救災相關資源易受其影響而難以第一時間投入。因此，災前預防性疏散避難及維持災害發生之搶救維生通道，顯得格外重要。鑒此，本研究依水土保持局所輔導550區土石流自主防災社區為基礎，建立可涵蓋全台範圍之坡地防災及維生通道區域路網計202個。後各道路以每200公尺為原則，劃分197,551段分析其致災潛勢，共劃定高潛勢982段、中潛勢19,461段、低潛勢177,108段。此資訊可供相關單位及民眾參酌，了解串接山區聚落或坡地社區至疏散避難處所之路線、災時較高潛勢之路段；當交通要道中斷時，以防災及維生通道作為替代道路，以利爭取防、救災及相關資源投入之時效性。

The extreme climate caused by global climate change, the increasing intensity and frequency of various disasters, has caused many settlements to lose external contact due to road interruption, and disaster-related resources are vulnerable to its impact and difficult to invest in the first time. Therefore, pre-disaster preventive evacuation and maintenance of rescue and life-saving channels are particularly important. In view of this, this study is based on 550 autonomous disaster prevention communities under the guidance of the Bureau of Water and Soil Conservation, and established a total of 202 regional road networks covering slope disaster prevention and life-staining channels throughout Taiwan. The subsequent roads are divided into 197,551 sections analyze their hazard potential based on the principle of every 200 meters. A total of 982 sections with high potential, 19,461 sections with medium potential and 177,108 sections with low potential are delineated. This information can be used by relevant units and the public to learn about the routes connecting mountainous settlements or sloping communities to evacuation shelters, and road sections with higher potential during disasters; when traffic arteries are interrupted, disaster prevention and survival channels are used as alternative roads, In order to strive for the timeliness of prevention, disaster relief and related resource input.
