基于动态实时监测数据的水污染模拟分析系统研究

以水污染应急事件中的水污染模拟分析为研究对象,从数据的采集、传输、模拟分析、应用等多层次出发,采用WebGIS为核心技术,建立了二维网络地理环境下的水污染模拟仿真决策支持系统。该系统重点研究了互联网环境下的二维水污染扩散模型和水污染模拟计算结果的可视化表达和交互应用。通过长江干流某河段的应用,验证了该研究系统的有效性和科学性,结果表明系统能够有效、科学支撑突发性水污染事件的自动监测和应急决策处理。

Simulation and Analysis System of Water Pollution Based on Dynamic Real-time Monitoring Data

In this paper, water pollution diffusion is simulated and analyzed by information and visualization tech-nology during water pollution emergency events. A simulation and decision support system for water pollution based on WebGIS is proposed to represent and manage data in two-dimensional network environment. Data is the key part of the system,including data acquisition, transmission, simulation analysis and application. In this system, the vi-sualization and interactive application of two-dimensional diffusion models of water pollution and simulation result are researched in emphasis in the Internet environment. A section of the mainstream Yangtze River is taken as the experimental region to test the effectiveness. Experimental result proves that the system could effectively support the automatic monitoring and decision-making of water pollution emergency events.
