By analyzing the characteristic and limitations of several typical spatio-temporal data models,the extension methods of improvement were presented for an event-based spatial-temporal data model in the paper.It was proposed using inherited relation could do history retrospect query effectively.According to practical application and based on the ARCGIS software,the model is developed and tested.The experiment shows that this model can mutual query with time,space and attribute,the separate storage and management of time and spatial object is useful to spatio-temporal analyses and causal reason between geographical event and spatial object,the storage space and redundance of data is reduced.
