The multi-factor spatial database of geological hazards in the studied area has been established by means of GIS��and determined the factor evaluation system which led to geological hazards�� According to the evaluation and classification criteria��the authors dealt with the influence factors of geological hazards using spatial data analysis method of GIS��and determined four geological hazard cluster areas using clustering analysis�� The Grade area �� was engineering activities dominant factor type��and mainly distributed in urban district of Fushun�� The Grade area �� was engineering activities induced factor type��and distributed in valley basin and marginal area�� The Grade area �� was engineering activities weak factor type��and distributed in northern and central hills�� The Grade area �� was natural factor dominant type��and distributed in southern mountain��
