Abstract
Information management of surface water pollution is one of the most important aspects of environmental management, which can effectively manage and visualize water pollution monitoring information. Water quality model is key technology of surface water pollution monitoring, which concerns about monitoring precision of pollutant concentration. Taking the design and realization of the surface water pollution monitoring information system in Xinxiang city, Henan province as an example, adopting component GIS technology and taking advantage of the perfect combination of Map Objects and Visual Basic 6.0, the paper discusses how to perform the secondary development by integrating water quality model and GIS. The system not only realized visual expression of surface water pollution situation and prediction of pollutant concentration, but also provided scientific methods and modern means for information management of water pollution in Xinxiang city. Keywords-GIS, MapObjects, Water quality model, Water quality pollution
