dc.description.abstract | 本研究以南投縣境內土石流發生區
為主要研究對象,提出土石流發生臨界降
雨線之設定方法,且針對南投縣內三十個
危險溪流樣本,進行土石流發生危險因子
之檢定分析。研究結果顯示土地利用因
子、溪床平均坡度及土壤粒徑大於四號篩
百分比等三項因子與土石流發生關係較為
密切。另由曾發生土石流的十三個溪流樣
本,配合通過檢定的危險因子,進行三維
費雪區別函數分析,建立土石流發生臨界
降雨線之預測公式,亦藉以推測未發生土石流集水區之臨界降雨線。 | zh_TW |
dc.description.abstract | The sites for this study were selected at
the places where debris flows had ever
occurred in the Prefecture of Nan-tou. In this
study, a method for determining the critical
rainfall line of debris flow occurrence was
proposed. Thirty high potential streams of
debris flow in the Prefecture of Nan-tou were
used as samples. Then, dangerous factors
affecting the occurrence of debris flow were
examined and analyzed. The results showed
that the land use factor, average slope
steepness of the stream and the percentage of
soil particles greater than sieve No.4 were
relatively highly related to the occurrence of
debris flow. In addition to this, three
dimensional Fisher’s linear discriminant
function was conducted using the dangerous
factors (which passed the examination) of the
13 streams in which debris flows had ever
occurred to establish the equations for
evaluating the critical rainfall line of debris
flow occurrence. Using the equations, the
critical rainfall lines of the watersheds in
which debris flow had never occurred could
also be evaluated too. | en |
