Abstract:In this paer,the consistency diffusion of the pollute materials is calculated on basis of the movement model and water balance model. According to the requirement of Geographic Information System(GIS), the spatial data and attribute data are formed quickly. The thematic auto classification and query sub system are complished. This system has been used for the diffusion of N, P in East Lake, Hubei province, and Cu in Chihu, Jiangxi province. The results meet the requirements of application. This is a test of combining Remote Sensing, GIS, Computer graphical technique and environment monitoring technique. Therefore it is very useful for monitoring and processing of lake pollution.
Keywords:Enviroment information system   Consistency   Spatial data   Water quality
