| Abstract: | Based on the graph theory with improved comprehensive criteria,a method to early warn the geological hazards was put forward according to the results of weight factor and early warning indicator calculation.With the application of Delaunay triangulation and the boundary conditions to automatically limit the subdivision,early warning of the geological hazards based on meteorological data was achieved by automatic calculating and identifying.The automatic calculation system was applied in Zhangjiakou City for... |
