| 摘 要： | 通过对金沙江向家坝库区长约150km范围内的55条泥石流沟发育状况统计显示。自库首至库尾。泥石流沟的数目、发育密度及规模均呈逐渐增强趋势。同时泥石流沟的流域面积、主沟长度及纵坡平均坡降均存在明显的分形特征，它们与沟道数目之间有良好的非线性关系，并在一定程度上揭示了这些泥石流沟谷形态演变的非均匀性和自相似性。

| Abstract: | Comprehensive investigation and systematic research on the debris flow in Xiangjiaba Reservoir area of Jinsha River have been conducted. It has been found that there are 55 debris flows occurred on the 150Km long valley along Jinsha River. The datum or density and scale of debris flow are gradually increased from Xiangjiaba upsteam to Xiluodu. Simultaneously,there is obviously fractal property in drainage area, main gully length and slop ration of debris flow. They are fine nonlinear correlation with debris flow datum. This phenomenon may reveal the nonuniformity of debris flow gully development. |
