In this paper,first,we have expounded the mathematical modeling method about basin palaeotectonic reconstruction.Then,we integrate this modeling method with GIS in order to expand the spatial analysis functions of GIS.Finally,a basin palaeotectonic reconstruction model based on GIS has been made,which includes a series of procedures,such as data_input,build_up of palaeotectonic reconstruction database,spatial analysis,generation of digital elevation model (DEM) of palaeotectonic surface,visualization expression of DEM,and geological analysis of palaeotectonic reconstruction map in different geological history period.As a case of application,using the model proposed in this paper,we has successfully reconstructed the palaeotectonic frameworks of the base of Permian in some area of southern China at the end of the Permian,Middle Triassic,Late Triassic and Middle Jurassic,respectively.By comparing the results with the research productions we obtained based on the combination of backstripping analysis method and other graphic display techniques in the same area in 1999,it is clear that reconstructing the basin palaeotectonic pattern based on GIS can not only gain satisfactory results,but also has a lot of advantages in aspects of graphic display,renewal of data and graphics,and assistance geological analysis.
