基于WebGIS的一维水体污染扩散模拟的实现

摘要

为了将互联网和地理信息系统(WebGIS)结合起来,并在不受环境限制的条件下模拟水污染扩散情况,从而及时有效地处理突发性水污染事故.对一维水体污染扩散的数学模型进行了重点分析和求解,并利用河道中的主要测试点数据进行编程,同时结合Web技术,提出了水污染事故应急分析中的一维水体污染扩散模拟实现方案.%By combining Web with the geography information system (GIS) , the diffusion of water pollution is simulated without any environmental constraint to handle the sudden water pollution incidents efficiently in time. The one-dimensional mathematlC model of water pollution diffusion is analyzed emphatically. A solution to realize the one-dimensional model of water pollution diffusion in the sudden watcr pollution incidents is proposed according to the author programs for the main data of the river channel in combination with Web.
