Abstract: There is a general consensus in both GIS and environmental modeling communities that the advanced integration of GIS and environmental modeling should be promoted. In environmental modeling, populations and species, environmental media, such as air, water, soil, and environmental chemicals are the basic units. Since all the basic units do have a spatial distribution, and this distribution does affect the processes and dynamics of their interactions considerably, GIS is good at dealing with the problem of spatial relationship and spatial distribution. The overlap and relationship between GIS and environmental modeling is apparent, and integration of these two fields is an obvious and promising idea. GIS can be used to account for spatial variability, which is an essential condition for the further development from lumped to spatially distributed models. GIS also can be used to prepare and management input data for environmental models, and their final result can again be used in a GIS as a user-friendly computer presentation. At the same time, environmental models can perform function which, in the main, current GIS lack, but which is important for solving environmental problems. Based on "Integration and Systematization of Mathematic Models for Soil and Water Resources Study in a Basin and Its Application", a NSFC Program, this paper analyzed the integrative relationship between GIS and environmental modeling and pointed out the inevitability of integrating these two research fields. According to the development of GIS technology and the improvement of environmental simulation models, the necessity of integrating environmental simulation models with GIS technology is discussed, and the conceptual framework and the different formats of integration are outlined in this paper.

Key words: environmental modeling, GIS, integration, simulation models
