The formation and evolution of geological hazards is subject to certain regional background conditions, that is, the regional geographical environment has a nontrivial influence on the spatial distribution of geological hazards. The geo-information tupu theory can express intuitively and simply the forming conditions and influencing factors of geological hazards through image thinking and expression ability of graphics language. Based on the spatial database of geological hazards, geo-information tupu theory and GIS technology, this paper indicates the relationship between the spatial properties of geological hazards and its factors in time and space distribution by tupu and analyzes the characteristics in space and the change process in time of geological hazards. The results show that the formation of geological hazards in the studied area are affected mainly by landform, stratum lithology, geological structure, rainfall and human engineering activities. The landform is the necessary conditions of forming geological hazards; the stratum lithology provides the material foundation for geological hazards to form and their deformation and destruction; geological structure has a direct or indirect control effect on the formation of geological hazards; rainfall is the main trigger factor of geological disasters; human engineering activities aggravates the formation of geological hazards.
