On the basis of mentioned above, the environmental geology research is analyzed, focusing on the application of GIS to the environmental geology field. The application of GIS to geosciences in the United States, Canada, UK, Australia and other developed countries as well as to geological mapping, database building and mineral resources prognosis in China is analyzed systematically and the prospects of the application of GIS to the field of the environmental geology are summarized. amespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
