Abstract: Based on briefly introducing the definition of geological hazards and geological hazards regionalization,the text expounds research status quo of geological hazards regionalization in China,and educes two methods of the study of geological hazards regionalization: the one is that sensitivity indexes are quantitatively and hemi-quantitatively ascertained by overlaying distribution map of geological hazards and the map of diversified factors, then division of susceptibility and risk are plot by overlaying sensitivity indexes;the other one is that according to the coefficient of weight and arithmetic of them,quantitative references of geological hazards regionalization are attained.At the same time,along with the development of technology of computer and GIS,traditional method of geological hazards regionalization is combined with the technology of GIS,which provides more visualized and better of quantitative degree in aspect of the division and assessment of susceptibility and risk susceptibility and risk.
