It is of great significance to land resource management in mining area and the decision making of land reclamation planning to establish land reclamation information system of mining area based on GIS. The spatial information database of land reclamation is a temporal database due to the change of land resource with the coal mining. In this paper, we analyze the characteristic of the change of land resource in subsidence area, integrate the advantage of Event-Orient spatio-temporal data model and Feature-orient spatio-temporal data model, provide an Event- and- Feature-orient spatio temporal model based on the research of predecessor, and give the data organizeing method of this model. We also study the inquiry and analystic method of temporal information. This model has the advantage of keeping the integrality of feature entity and less data redundancies, and is easy to organize the spatio-temporal data in the traditional GIS.
