Based on the seismically hydrogeochemical survey,a new MIS system named seismic hydrogeochemistry database management system(SHCDMS) has been developed successfully.The system was written in FoxPro2.5 environment under UCDOS(Chinese DOS operation).The system can manage daily data of hydrogeochemistry observation station and give out all kinds of reports and charts needed.The system has a good user interface and sufficient function.Through two years running,it is shown that the system fits in with the need of analysis forecast center and observation station.
