Application of BP model to landslide hazard risk prediction;

Study on multi-attribute decision method for treatment of landslide hazard;

This article comprehensively introduces landslide disaster occurred in the Huaying Mountain area for recent years,based on the geographical position of the Huaying Mountain.

On the basis of the analysis of historic landslide disaster harm to local society and economy,disaster land status quo and features in Three Gorges area,through investigation of technologic method,structural measures,social and ecological effects of typical Xintan landslide disaster land treatment,the general treatment mode of landslide disaster land treatment in TGP reservoir area is summarized.

Study of population vulnerability and risk forecasting of population casualty during landslide hazards is important for regional landslides warning,which provides key operation for improving pertinence and validity of landslides warning.

Loss assessment of the damage of landslide hazards is an important research content of risk evaluation of landslide hazard,and at present the index system and model of loss assessment of the damage of landslide hazards are imperfect.

On the basis of investigation and statistic analysis of the landslide hazards in the reservoir region of the Three Gorges project on the Yangtze River, the critical phenomenon and triggering conditions of different deformation phases are analyzed in the representative landslides, and twenty seven criterion landslide warnings of 3 hierarchies are proposed.
