Abstract: In this paper，Badong county is chosen as the study area because of the development of geological hazard，and the disaster points are as the sample data.Firstly，GIS is used to overlay the disaster points and other factors，such as formation lithology，elevation，slope，aspect，stream combination and land-use classification of remote sensing images.And then the attributes of disaster points，for example，the type，the scale，the material，the difference of elevation，the river bank，are selected and using Apriori algorithm for mining association rules between the selected attributes and the overlaying result.Finally this paper mines the single factor association such as the disaster scale and the stream combination，and the multivariate association such as the attributes of disasters and the related factors.Compared with the previous research results，the rules are in accordance with the actual situation and can provide transcendental information and knowledge for analysis and decision in geological hazard.
