Abstract:

At present the methods of geomorphology research can be summed up as follows: 1)field investigation and record; 2) orientated observation and field experiment; 3) indoor experiment and geomorphic simulation. The history of geomorphology indicates that the experiment and simulation (BSG) is the main direction of modern geomorphology research.The establishment of GIS provides new technological equipment for ESG. Relying oncomputor, the GIS can improve the function of ESG and even can simulate the geomorphicprocess. Because of the incompleteness of GIS and the complicacy of geomorphology, there are some difficulties which are preventing the GIS from popularizing on ESG in spacial data input, spacial inquiry and the establishment of Seomorphic model. Founding a new structure of data, adopting object-oriented model and fuzzy mathematics may be effectivecountermeasures against the dificulties.
