Landslide Susceptibility Analysis Based on Data Field
The Three Gorges are the areas in which the geological disasters are very serious. There often happen great landslide disasters, which brings tremendous threat to normal running of the Three Gorge Dam and the properties and lives of the residents in the reservoir. So landslide susceptibility analysis is an important task of prevention and cure of landslides in the Three Gorges. In this paper, landslide susceptibility analysis in the Three Gorges is studied based on spatial data mining. ETM+ image, 1: 50000 geological graph and 1:10000 relief map are adopted as the data origins to produce the factors closely related to landslide transmutation, including slope structure, engineering rock group, slope level, fluctuation influence of reservoir water and land exploration.
