Abstract：In this paper synthectical prediction was conducted for space prediction on land?fall and rockfall of two administrative levels. On the basis of investigative and statistic data， this paper first presents macroscopical regional prediction of landfall and rockfall by statistics method of information quantity，then predicts microscopical stability grade to find sites of landfall and rockfall by the synthesis judgement method of fuzzy. The results coincide with the actual condition of landfalls and rockfalls fairly well showing the feasibility of the method.
