Abstract

Based on Remote Sensing and spatial analysis of GIS, the paper assesses the geological hazards risk of Laoshan district of Qingdao city from six aspects: landform and physiognomy, geological condition, climate and vegetation, hydrological condition, human activities and status of occurred disasters. In the study process, AHP is used to determine the weight of those factors, and WCA is used to build the model of geological hazard evaluation. The result is consistent with the actual situation, and it shows credible with these methods to risk evaluation of geological hazards. It is concluded that the evaluation result is credible.
