中文摘要 | 土石流之發生除了降雨係主要因素外,另外地形因素如溪流坡度、溪流長度、溪 流寬度、谷口上游之集水面積及地質種類、地表植生、上游崩塌地、溪床堆積物特性、地下 水位等等皆是促成土石流形成之重要因子。因此,本文主要將土石流流動系統視為一灰色系 統,應用灰色相關理論分析探討因子參數中降雨量、時雨量、溪流坡度、溪流長度、溪流寬 度、谷口上游集水面積等對土石流發生及土砂流出量間關聯程度排序。由本研究得知發生土 石流因子中其灰關聯度以最大時雨量為最大,次為溪床坡度,再次為集水面積,溪床長度而 以溪床寬度最小。其次並對土石流土砂流出量之大小利用灰關聯理論分析,發現影響土砂流 出量之參數中以溪床寬度之關聯度最大,次為溪床坡度,再次為集水面積,關連最小者為時 雨量。 |
英文摘要 | Debris Flow occurred was influenced by many factors. Precipitation is the main factor and the other factors are topography, surface cover, landslide, material properties, groundwater and geography which includes stream slope, length, width and watershed area. Therefore, debris flow motion can be described by grey system. Using this theory to analyze the order of those factors that cause debris flow, the results show that grey relation of the occurrence of debris flow is precipitation intensity as the first order, secondary is slope, third is length and last is width of stream. Similarity to analyze the order of factors of outflow of debris, stream width has the best order, secondary is slope, then watershed area and the last is intensity. |
