Abstract


As in recent years, the rapid development of China's economic , social , life , the rapid growth of production and water consumption , but at the same time a large number of untreated wastewater discharged into rivers and lakes , causing serious water pollution problems , and hinder economic , the further development of the society . In order to respond promptly to the lake water pollution accidents , lake water quality model for dynamic simulations it is very important for the concentration of pollutants in the water column . The lake water environment due to the terrain , environment , climate , pollutant emissions , many factors become very complex , and GIS data acquisition , editing, and powerful spatial query and analysis capabilities . Unfolded and can kind of complex changes in graphical form . Integrate GIS and water quality model of the diffusion process of water pollution can react can very vividly reflects the changes in water quality conditions and trends . Lake water quality simulation system based on WebGIS spatial data and attribute data associated with the water environment as the core , the WebGIS technology used in water quality modeling by the lake water quality model and WebGIS integration of water environment information processing , analysis and visual expression . This paper focuses on the ways and means of integrated GIS and lake water quality model . And design based on lake water quality simulation system based on WebGIS system to Kara Wu Shefu water diffusion model , for example , to simulate the diffusion of pollutants in lakes . The main content of this paper is as follows : (1) in order to the Kara Wu Shefu water diffusion model example of lake water quality model has carried out a detailed analysis and discussion . ( 2) research to build the lake water quality simulation system key technologies , including RIA, WebService, WebGIS technology . ( 3) an integrated approach to the study of water quality model WebGIS . (4 ) to establish water quality simulation system , the water quality model and WebGIS integration , visual expression processing and water quality modeling of water quality information .
