摘要：
The paper is based on the data of national geological hazards from 2000 to 2012. It uses the grey relational analysis to calculate the weight of index, and then establishes the assessment model of grey relationship to evaluate the loss of geological hazard and analyzes the trend of hazard according to the time sequence. The results tell that: in 2012, the most serious province suffering geological hazard are Sichuan, Liaoning and Yunnan, especially Sichuan province. In macro level, the geological hazards present rule of cyclical interannual variation law, but from 2000 to 2012, the trend of geological hazards declines steadily and slightly.
