- Abstract:
- The influencing factors which control the landslide occurrence mainly include lithology, geological structure, topography, precipitation and so on. The status of the factors in landslide evolution is different, and can be expressed by weight. As considering the scale characteristic of the landslide and its influencing factors, it is inevitable that the result of landslide hazard assessment would be influenced by scale effects, which mainly represents the change of the weights of landslide influencing factors with the change of the scales. We compared and analyzed the result of the landslide assessment which obtained before and after the weight of factor modification. The result showed that on the small scale, the weight of these factors of which the rate of spatial change was slow such as lithology, topography, precipitation and so on, would be smaller, however, the weight of other factors of which the rate of spatial change was rapid, such as slope, aspect slope and so on, would be greater; on the large scale, the weight of landslide influencing factors was contrary direction to change.
