摘要

土石流發生的主要控制因子爲降雨，堆積物、坡度、集水面積等，惟各因子間的相互影響關係難以明確界定，其間包含一定程度的模糊性，本文主旨卽在說明如何將模糊集理論中的模糊控制理論應用於土石流預警模式中，擬定土石流預警系統的控制元件，以作爲土石流發生之預測判斷，同時將降雨、坡度、集水面積等因素同時考慮下進行研究，與國內已發展的方法進行比較，以期對土石流發生之預警系統能更有效的運作，以使人員及財産的損失減至最低，本研究之方法亦可應用於危險區域的判定以作爲土地開發的參考。

The major control factors of the debris flow are rainfall, pile, slope, and watershed area; nevertheless the mutual relation of these factors has not been clearly defined, i. e., its involves a certain kind of fuzziness. The main purpose of this study is to investigate a methodology of applying the fuzzy control theorem for debris flow estimation and forecast. The debris flow warning system includes the factors of rainfall, slope, and watershed area simultaneously, The method is compared with a previous study (Shieh et al., 1992) based on excuted several debris flow events obtained from Hua-liem and Tai-tung counties in east Taiwan. It is our hope that these efforts eventually can help us to develop an efficient and accurate debris flow warning system so that the loss of personnel and property can be reduced to the minimum. The method developed in this study can also be applied for classification of the unsafe region in land development.
