Abstract:Debris flow is one of he main natural hazards in mountations areas. An annual economic loss brought about by debris flows is more than two hundred million yuan in China.To design a debris flow information system in county grade can provide a strategy for prevention and control of debris flows and put forward a decision support for governments.Debris flow hazards are serious in Danba county, Sichuan province. There are 81 debris flow gullies in the county, and 5 of them endanger the county town. Debris flow information system in county grade can directly serve for reducing debris flow hazards in the county. According to the rnethod of software engineering, the system designing includes five steps, i. e. system analysis, general designing, detailed designing, coding designing and software management. The application of the system main1y included database management system, map management system, zoning of debris flow hazards, and two types of identification models of debris flows. The system can be run in PC486, so its application prospect is vast' The system will p1ay an important role in reduction of debris flow hazards and econmic development in mountainous area.
Keywords:debris flow  information system  application  Danba County
