The landslide happened to the country and brought the big disaster, with 3 S technology rapid development, RS, GIS are widely used in landslide risk division and prediction research. Especially the GIS technology, because its storage layers of the hierarchy, the mining and more calculated the promptness of geological data and space form of simulation super ability, for landslide disaster accident prediction provides new train of thought and method. In this paper for the object in GIS landslide research on the basis of landslide disaster accident forecast system, we established the landslide database first, then according to the characteristics of the landslide put forward a variety of landslide forecast and the forecast of space time model and method, in view of the different situation will be the model and method is compared, and choose the optimal model method and data together to be able to display and intuitive output the landslide forecast results, to predict the landslide disaster forecast lastly.
