| 摘 要： | 通过对某水电站库区内12条主要的泥石流沟从沟道数与流域面积,沟道数与主沟长,沟道数与沟谷坡降关系上研究了库区内泥石流沟发育的非线性特征,并通过其双对数曲线方程得到了各自的分维数,其意义是在对泥石流危险度评判中为各因素权重的求取提供一个定量的手段,并据此可利用非线性技术来解决泥石流灾害研究中的预测及防治等主要问题,为泥石流灾害防治提供新的思路。 |
| 关 键 词： | 泥石流 沟谷特征 非线性 分维数 |

| Abstract: | Through the study of the correlation of mud stone flow datum between drainage area, main gully length and slope ration of mud stone flow a study about the non-linear property of gully of twelve main mud stone flow on the some reservoir area has been conducted, then we get the fractal dimension through the log-log plot yield, it is a new method to get the weight of each factors to evaluate the hazard degree of mud stone flow. Base on this, also we can use the technology of non-linear to resolve the problem of mud stone flow. |
| Keywords: | Mud stone flow property of gully Non-linear property Fractal dimension. |
