摘要

本文參考經濟部中央地質調查所於95年完成之「都會區及周緣坡地環境地質資料庫」圖資，完成土石流地質災害敏感區納入土石流潛勢溪流之可行性分析程序，檢討土石流地質災害敏感區溪流兩側50m內總計大於一戶保全對象者，比對行政院農委會水土保持局公開的1,552條土石流潛勢溪流，剔除已公開溪流後，即完成都會區周緣坡地新增土石流潛勢溪流建議清單，透過空間分析與現地調查結果探討土石流地質災害敏感區納入土石流潛勢溪流之可行性，其成果可供土石流防減災及風險管理參用。

This study aims to develop a feasibility procedure of incorporating debris flow geological sensitive area into current debris flow potential torrents, that utilized information from Environmental-Geological Database of slope-land by Central Geological Survey and building distribution to identified possible potential debris flow torrents. Review 50-meter buffer zone of debris flow geological sensitive area is more than a building, and excluding the debris flow potential torrents by Soil and Water Conservation Bureau. Through spatial analysis and investigation of debris flow geological sensitive areas were extracted, overlaying it with possible exposures and identified possible potential debris flow torrents for future applications. The results could be utilized in improving debris flow hazard mitigation, hazard reduction and debris flow risk management in the future.
