THE FRACTAL DIMENSIONS OF LANDSLIDES AND SIGNIFICANCE FOR THEIR PREDICATION

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.
