Abstract On the basis of combining with the relevant industry standards and considering the factors of engineering importance and hazards stability，hazard rating assessment system(HRAS) of surrounding slope，which has enough easily valued indicators，is established according to 3 first level indices (the hazard source，path and inducing factors)；9 secondary indices(stability，potential energy，hazard sources shape，paths geometric features，vegetation growth，earthquake and rainfall) and 35 basic indices. According to the level of values ，hazards rating is divided into 3 levels—high，medium，low level. Taking the surrounding slope of ground powerhouse as an example，there are 12 hazard sources of 3 high hazard rating and 9 medium. The result is largely correspondence to reality. and the system can correctly evaluate the risk degree and make guidance for dangerous source prevention and controlling.

Key words： hydropower engineering hazard source hazard rating Busigou hydropower station
