WebGIS-based steel plant pollution tracing method and system

The invention discloses a WebGIS (Web Geographic Information System)-based steel plant pollution tracing method and system. Comprising the following steps: 1) saving and recording pollutant emission information of the whole plant; 2) detecting related pollution conditions in real time; (3) relevant data after a certain monitored pollution value exceeds the standard are sent to a pollutant tracing module; 4) calculating latitude and longitude coordinates of the pollution source according to the current environment condition; 5) matching the calculated latitude and longitude coordinates of the pollution source with pre-stored pollutant emission information; and 6) if the matching is successful, judging the pre-stored pollutant discharge information of the address and judging the raw materials which possibly generate the detected pollutants. According to the invention, air pollution of a specific industry is traced, and a production plan and real-time production data of the whole plant are introduced, so that po
