摘要:The river network in the Four-lake Basin of Hubei Province is staggered with a complicated water system and is seriously disturbed by human activities. Therefore, the real-time monitoring and management of its water environment is of great significance to the sustainable development of the basin. As the application of WebGIS becoming increasingly extensive, applying WebGIS to the monitoring and management of basin water environment can satisfy the demands of various users, such as governmental departments, general users, and researchers in the context of increasingly-prominent water environment problems in the basin. The WebGIS technology has utilized to realize the functions of displaying, spatially querying and analyzing water environment basic information such as hydrology, water quality, meteorology and natural reserves in the Four-lake Basin. Users can easily access and obtain relevant real-time dynamic information through the browser for spatial analysis, such as the assessment of water eutrophication and the diffusion analysis of wastewater pollutants.
