Abstract
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.
Highlights
The health of water environment in the basin is an important foundation for developing regional economics and production activities [1,2]
The study can provide a strong support for the scientific decision-making of the river basin management department, general users, and environment assessment analysis
The function of the geospatial operation interface to provide querying buffer and querying geometry on ArcGIS for Server, whereas that of the attribute operation interface consists of querying data indexes, such as water quality and meteorology
Summary
The health of water environment in the basin is an important foundation for developing regional economics and production activities [1,2]. A great number of WebGIS platforms concerning water ecological environment, such as water resources assessment [3], soil and water conservation [4], flood prevention and dispatching system [5], have emerged at home and abroad, aiming at promoting the sharing, comprehensive application and integrated analysis of water environment data. Most of these systems can provide the functions of querying and analyzing, such as querying and downloading water environment data [6-7], while few of them can have more spatial analysis functions, such as buffer analysis, geostatistical analysis, and inverse distance weighting analysis [8-9]. The study can provide a strong support for the scientific decision-making of the river basin management department, general users, and environment assessment analysis
