The landslide stability evaluation method research in the Three Gorges reservoir using ZY-3 data

In this paper high resolution remote sensing data (ALOS and ZY-3) and abundant geological data were applied to analysis the weight of the influence factor of landslide in the Three Gorges area. The evaluation factor includes engineering rock group, human activity, hydrogeology, etc. The multivariate statistical analysis strategy was applied to confirm the weight of each factor. Results show that the method plays more attention to the surface and strata. Its accuracies could be greater than 94%. The result is more close to reality. This method can be presented as a new means for stability evaluation of the geological disasters.
