Study on risk assessment of geological hazards in Huizhou District, Huangshan City, Anhui Province

The mountainous area in southern Anhui Province is a high incidence area of geological disasters. This paper chooses Huizhou District of Huangshan City as the research area. According to the characteristics of landform and geological structure, eight impact factors, including elevation, slope, slope direction, fault structure, water system, land cover type, engineering geological rock formation and human activity intensity, were selected as the risk assessment indexes of geological disaster. Combined with the field survey results of geological disasters, the risk assessment of geological hazard in the study area was carried out by the method of information quantity model. A geological hazard assessment model suitable for the southern Anhui mountains was established.
