Abstract
In recent years, the frequently occurring contamination accidents in the chemical industry parks in China has posed great threats to the healthy development of the national economy and social stability. For this purpose, this paper conceives a set of dynamic surveillance system against such accidents, which, on the premise of rapidity, simplicity, and reliability principles, revamps and redesign the HYSPLIT air pollution model for the interface, architecture, and functions, wholly integrates with air pollution diffusion model, numerical meteorology forecasting model, and the Geographic Information System (GIS). With the business operation mode, this system can effectively warn against the “uncertainty” of atmospheric pollution events in the chemical industry park, timely access the information about whether any pollutant exceeds allowable limits when an accident occurs. In the response to the emergency accident, it enables quantitative analysis and visual expression on chemical pollutant concentration limits, development trends and health risks, so as to provide an effective business and information support for decision commanders.
