Abstract: A scientific and rational knowledge of geohazard susceptibility assessment is of vital importance to the warning of regional geohazard. Based on geohazard field investigation of Pinggu District at 1:50000 scale and geohazard database established subsequently, the development characteristics, spatial distribution and influence factors of geohazards were obtained. Factors such as engineering geological strata, slope gradient, tectonic fault, human engineering activities and vegetation coverage have a significant impact on the evolution of geohazard, they was comprehensively analyzed through the spatial tool in GIS.Using frequency ratio evaluation, geohazard susceptibility assessment of Pinggu District was carried out. Results showed the distribution of geohazard in Pinggu District had a close relationship to regional landform, faults and human engineering activities, which was consistent with actual conditions. According to the evaluation, the whole area can be divided into four areas: the high susceptibility of geohazards area, which covers 125.6km2, accounting for 27.3% of the total studied area the medium susceptibility of geohazards area, which is calculated 273.02km2, accounting for 13.3% the low susceptibility of geohazards area, which is measured 326.89km2, taking up 22.7% and the stable area covers 349.49km2, accounting for 36.7%.The results can provide a guideline for the mitigation and prevention of geohazard in Pinggu District.
