| 摘 要： | 本文依据分形理论，采用盒维数法计算了西藏樟木地区滑坡及其水系的空间分维。分析了分维的变化特征。发现滑坡高潮期前存在不同幅度的降维现象，滑坡区滑坡活动程度不同，其水系分维在不同观察尺度下变化幅度有显着的差别。探讨了分维的预测意义。

| Abstract: | On the basis of fractal theory,the spatial fractal dimensions of landslides and water system in Zhangmu area are claculated by box-counting method in Tibet.The variation features of fractal dimensions are analysed.The results shows that the lower fractal dimension phenomena of different amplitude exist before high activity of a landslide.The activity climax period.The extent of landslides activities is different in a landslide area,where the variation of fractal dimensions of water system is evidently different in different measure scales.The authors also discuss the significance of fractal dimensions in prediction of landslides. |
