Based on massive monitoring data of Lake Baiyangdian and the important advantage of spatial analysis functions of GIS (geographical information system), a system of B-WEIS (Baiyangdian water environment information system) was designed in the work. Component GIS of ArcEngine 9.3 GIS, combined with GIS and component technology, was used to research and develop the proposed system. This system realized different functions of management, data query, statistic analysis and visualization query to the Lake Baiyangdian water monitoring results. It also integrated with professional water quality model to realize evaluation of water quality and calculation of environmental capacity function. The designed system contributed to expand the management on Lake Baiyangdian more professional and available.展开更多
