The cause analysis of landslide disaster

Abstract

Abstract In this paper, the mechanism of landslides, induced factors, geological characteristics and environmental characteristics of historical landslides are analyzed. The application of geographic information technology in landslide prediction and evaluation is introduced. The indexes combined with the GIS system are then extracted for the data simulation by analyzing the relationship between the internal factors and geomorphology in the landslide occurrence. On the other hand, it is pointed out that the by-product of civil engineering is the important risk source of increasing landslide disaster. This improves the reliability of the prediction and evaluation for landslide disaster and is of great significance for future observation and prevention of landslide.
