摘要

桃芝颱風造成花蓮大興部落空前災難,人與大自然如何和諧共處,永續的土地利用乃成為當前嚴肅面對的課題。本研究試就坡地崩塌、土石流發生,應用GIS與DTM之室內分析,了解某地區之潛在坡地敏感區的基本特性,並配合野外實察相互印證,以得出坡地敏感度評估之架構,作為嗣後推廣應用和經營管理之參考。
為求理論與事實彼此扣合,本研究也鎖定花東縱谷光復鄉清水溪為研究單元,由該溪之水文特性、地質構造、地形計測再溶入系統空間分析功能與資料展示能力,得出該地坡地敏感區特性並繪製潛在坡地敏感區分析圖,冀使坡地敏感度有效的研究模式,跨出新的一步。

Typhoon Tau-Chi has caused the devastating destruction of Dai-Shen Village and has led us to a serious topic of how human and nature should live harmoniously and co-depend on each other. This research uses GIS and DTM to analyze landslides and waterflow to understand the potential characteristics of sensitive relief. With the practical field work to testify the hypothesis, assumptions on the directions of distribution of relief can be conducted, which are useful references for future generation.
To ensure that theories and facts are not conflicting each other, this research has targeted the Hua-Tong valley Kung-Fu County as our research base unit, based on the area’s hydrolic attributes, geological structures and system special analysis, we can detect the sensitive characteristics and draw out the potential sensitive area analysis graph which is an extremely effective research method and give us a new milestone in this field.
