Information Quantity Model Applied in Hazard Evaluation of Landslides—A Case Study of Fuling, Chongqing
Abstract— Based on RS, GIS technology and information quantity model, this paper will focus on the
research of hazard evaluation method of landslides disaster in Fuling, Chongqing. Combining with
theoretical basis of information quantity model, the evaluation method of this paper gives an improved model,
and adds impacts of four dynamic factors: rainfall, water level changes, vegetation and landuse. It was agreed
that the hazard evaluation result of landslides can be divided into five grade level: very high, high, moderate,
low and very low. According to the comprehensive evaluation, the result shows that the improved
information quantity model and the additional dynamic effects are reasonable, and demonstrates that this
method is objective and can provide effective guarantee for geological disaster prevention of the research
area. The whole evaluation functions of the hazard evaluation system of landslides are finally realized on the
ArcGIS platform with its modelling capabilities and custom development mode.
Index Terms— information quantity model, hazard evaluation, remote sensing, GIS.
