| Abstract: | Geological hazards occur mayinly as collapse, slope slip and mud flow etc. in Xiuyan county. A great deal of field investigations have been done and a lot of data were collected to set up Access database of the hazards. By using the function of the GIS software platform's projection change and spatial analysis divisions in which geological hazards tend to occur are classified into varied degrees. Combined with geological hazard occurrences vs rainfall relation are put forth the critical rain fall at which the hazards take place to gether in the divisions and the preliminary releasing program of geological hazards is established based on the weather forcast. |
