Abstract: In the production of hazardous chemicals present through the use or process of enterprises and institutions to investigate, determined the focus of prevention in Fushun City, and established a spatial database of dangerous goods and hazardous source spatial database. The environmental mathematical model was integrated into the geographic information systems, the use of geographic information system software MapObject and programming software Visual Basic 6.0, established Fushun unexpected environmental pollution emergency information. The system can simulate the migration of pollution diffusion process group to predict pollutant concentration and time of arrival, location in the event of accident quickly and easily in the event of accident, warning information timely in order to start the plan, prevent and mitigate the losses caused by pollution.

Key words: Unexpected environmental pollution emergency, Environmental mathematical model, MapObject, Emergency information system

摘要： 通过对抚顺市在生产和使用过程中存在危险化学品的企事业单位进行的调查，确定了抚顺市重点防范对象，并依此建立了危险品空间数据库和危险源空间数据库。将环境数学模型整合到地理信息系统中，采用地理信息系统软件MapObject和可视化编程软件Visual Basic 6.0，建立抚顺市突发性环境污染应急信息系统。通过本系统，在出现事故后，可以迅速地模拟污染团的迁移扩散过程，预测污染物浓度及到达时间、位置，及时提供预警信息，以便立即启动预案，防止和减轻污染造成的损失。
