Abstract. The threat to people's lives and property safety posed by landslide disasters has aroused great concern of the researchers in China. Landslide monitoring and forecasting is an important means to prevent and mitigate landslide disasters. Determination of the forecast criteria is a key technology of the landslide monitoring and early-warning systems. Some forecast models taking single parameter as forecast criteria and some other forecast models using the comprehensive forecast criteria are introduced. The multifactor comprehensive forecast model based on geological analysis, simulation analysis, and intelligent information technology can fully reflect the personality characteristics and evolution process of landslide, so it can ensure maximum effectiveness of the monitoring and early-warning.
