Research on Visualized Information System of Reservoir Ecotope Based on WebGIS

摘要

This research take the reservoir ecotope data as an object, facing reservoir management and decision-making. Saves the space geometric object data and the attribute data integration to the SQL Server2000 relational database through SuperMap SDX+, subsequently realizes the data management and maintenance. Uses JFreeChart technology, with which realizes the historical data front end statistical graph demonstration function. Provides a way to water quality evaluation model sequencing using Java programming language, Supermap Is Java controls and Ajax technology, by which make the reservoir ecotope evaluation more easier. At last, the research gives the Liuxi River reservoir as an example to show the main function and the visual effect. Key Words: reservoir ecotope, management information systems, data visualization, WebGIS, statistical graph
