ABSTRACT
As one of the world’s largest hydropower projects, the Three Gorges Project has attracted attention for its potential impact on ecosystems and socio-economic stability. Landslide is an open system of exchanging materials and energy with the environment, so it can be measured and described by information entropy method. The entropy of landslide refers to the extent of various factors influence the landslide development. Landslide is an open system of exchanging materials and energy with the environment, so it can be measured and described by information entropy method. Index factors selection and weight determination was the nucleus of typical landslide hazard degree assessment. To eliciting objective weight of index, information entropy method had to on the premise of a certain amount of available information, in other words, a deal of landslides with explicit factors should be prepared for entropy analysis. Typical landslide hazard degree assessment was a comprehensive assessment method.
