Abstract: Geographical information system has been extensively applied in many domains because of its great capability in obtaining, editing, managing, analyzing and displaying the spatial and non-spatial data. Since their initial development in the 1960 s, GIS have been used for study on solute transportation in soil by many researchers. However, for modeling solute transportation in soil, there is a big gap between requirements of model users and functions of GIS. Being connected to environmental issues, it has been a hot subject to study on moisture and solute transportation in soil. Because the properties of soil have strongly spatial variability, there is an emerging trend to study those issues by coupling vadose models with GIS. By this way, researchers can study solute transportation in regional scale quantitatively. The technology of computer is getting a high speeding progress now, so is GIS. By coupling models with GIS, or building models on the theory and technology of GIS, researchers will have bright opportunities to describe the solute transport and its influence on environment more deeply and precisely.

Key words: Geographic Information System (GIS), solute transport, models
