应用可能性线性回归模型来分析影响崩塌体所能到达范围的因子,结果表明:崩塌源头坡度是首要因子,其次是下游坡面坡度和集水度及崩塌深度和土质。在这些因子中,有60%取决于崩塌体规模和性质,而40%取决于流动坡面状况,二者均有必要参与分析崩塌体所能到达的范围。应用该分析法可以很简便地确定崩塌体所能到达的范围。这一方法应用于其它研究领域不但可以增加模型的预测精度,而且能预测崩塌体所及范围的危险程度,特别是对于较长历时的山洪更能说明问题。
The linear regression model is used to analyze the factors that affect the reach of the collapse body. The results show that the slope of the collapse source is the primary factor, followed by the slope slope, water catchment, collapse depth and soil quality. Of these factors, 60% depend on the size and nature of the collapse and 40% depend on the condition of the flowing slope, both of which need to be involved in the analysis of the extent to which the collapse can reach. Using this method of analysis, it is easy to determine the extent of collapse that can be reached. The application of this method to other fields of study not only increases the prediction accuracy of the model, but also predicts the danger of the extent of the collapse, especially for long-duration flash floods.
