Establishment of a cellular automata model for the prediction of landslide based on GIS technique

Currently the geographic information system (GIS) is mainly applied to describe and analyse static information of space, lacking of analysis of space-time and ability of dynamic simulation.. The changes of landslides can be recognized the spatio-temporal process, bringing new challenge and need to GIS analysis of space. Cellular automata Cellular automata (CA), is a "bottom-up" dynamic simulation modeling and simulation frame-work , which is naturalness, rationality and feasibility in simulating the space of complex systems with space-time dynamic evolution . Using loose coupling method to integrate the GIS technology and CA , establish a suitable forecasting model of highway landslide disaster, and forecast the development trend of Da Zha Zi landslide by using CA model.
