Loess Plateau is one of the birthplaces of the Chinese nation.It is also the youngest plateau and has been rising ceaselessly in our world.Besides,it had been recorded the information of global change in detail during the Pleistocene epoch,especially in the aspects of climate changes and geological hazards.According to the statistics of geological hazards in China,there are almost one third of cases in this area.These geological hazards caused great loss of life and properties.Hence,the mitigation of geological hazards in Loess Plateau is urgent and necessary.This paper summarizes geological hazards in Loess Plateau.Moreover,according to the results of previous research and engineering geological investigation,the critical issues and creative concepts,such as the couple analysis of soil mechanics and engineering geology,triggering and evolution mechanism,early warning system and so on,are suggested to mitigate the geological hazards in loess area.
