Risk Assessment of Geological Hazards under Multiple Rainfall Conditions——Taking the Key Survey Area of Fuch-uan Yao Autonomous County in Hezhou City as an Example
According to the quantitative calculation results,the geo-logical hazard zoning of the key survey area in Fuchuan Yao Au-tonomous County in Hezhou City was carried out,and the visual-ization was achieved through GIS software.According to the evalu-ation results of geological hazard under different rainfall condi-tions(rainfall once every ten years,once every twenty years,once every fifty years,and once every hundred years),the risk is classi-fied into four levels:extremely high,high,medium,and low.
