Abstract：Based on the integrating technology of landslide monitoring and three-dimensional geographic information，a monitoring information system of three-dimensional landslide is proposed. Subsequently，the synthetic expression of in-situ monitoring information and three-dimensional geographic information is implemented in the system，which provides an information platform for the synthetic analysis of monitoring scheme and its visualization. Aiming at the nonlinear evolutive problem of landslide displacement，the basic ideas of time series are employed，and the genetic algorithm is used in determining the structure and parameters of the time series model which are then used in the construction of the predicting model for landslide deformation. The Bachimen landslide of Funing highway，Fujian，China，is taken as an example to show the basic structure，functions and algorithm of the system of three-dimensional monitoring information. In addition，the landslide displacement based on the in-situ monitoring data is predicted.
