摘要

本文從土石流扇狀地的形成過程，論述其地形特徵、成災模式及堆積機制，以解析土石流扇狀地的堆積及發展趨勢。同時為有效治理與管理土石流扇狀地的危險區，以減少或避免災害發生，針對其劃定為特定水土保持區的技術原則加以評論，並提出建議。

This paper introduces the formation of debris flow fan according to the mechanism of deposition from debris flow. And the developing process of debris flow fan, which is influenced by geomorphological factors, damaging scales and depositing conditions, is discussed in order to grasp the dangerous zone. Meanwhile, the technical principles for the delimitation of dangerous zone as the designation area of soil and water conservation also are mentioned for management and protection to minimize or avoid the risk of debris flow.
