The Effect and Signification of GIS and EIS on the Research of Environmental Geology

Environmental problems will be more serious in the world in the 21st century, so environmental geology should make more contribution to study and resolving of these problems. However, the methods and instruments that are used on environmental geology do not satisfy external need. This paper discusses some problems about establishing EIS (Environmental Imitation System) and coupling GIS (Geographical Information System) with EIS. Through research, the authors suggest that these problems have been resolved basically. The coupling technology could remedy some defects of the function of environmental imitation in GIS and make EIS into space management system of information in which space information are managed, appliance analyzed and spliced, and made videotex. In the end, the paper indicates that co-system of GIS and EIS can be established to accomplish interchange, second developing and using of information.
