Component Of Forest Fire Suppression Decision Support Information Systems Development

The forestry in our country has undertaken the significant mission to build ecological environment and promote society sustainable development in society in 21 century. The forest is the main part of ecological environment. But when the forest environment system takes shape, fire takes part in the evolution and development of ecological environment. Forest fire has its broadest affection scope and the hugest destruction to society, environment and economic development in forest calamity. The occurrence of forest fire has its necessity and emergentness. If we want to control forest fire better, it is needed to monitor it and adopt effective measures to put out a fire and evaluate losing of forest fire.The forest fire protection auxiliary decision system is a professional application system that develops from the integration of the forest fire protection technology, the computer technology, the geographic information system technology, the satellite remote sensing technology, the networking as well as the database technology. It is the organic constituent of forest fire protection information system. It provides scientific and prompt reference basis for forest fire extinguishing and assists the decision-making department to carry on fire extinguishing decision-making through fire monitoring, querying of information for forest fire, loss pre-appraisal on forest fire as well as the best route analysis for putting out a fire and so on.At present the forest fire protection auxiliary decision system of foreigns has come into the age of digitalization and networking. The System will merge the characters of networking, large screen of show, GIS, video frequency, tracking, transmission of fire image, monitoring of the forest fire. The foreigns are developing the forest fire protection information system on the base of the characters of the forest fire.The auxiliary decision system is also the weak link in the building of forest fire protection information system in our country. For example, we can't forecast and discover fire exactly. When the forest fire has appeared, it depends on manpower and using some primary fire suppression tool mostly. It arose a plenty of consume of manpower, material resources and finance.All of provinces are developing the forest fire protection auxiliary decision system after 1990s.The author using the forest fire protection technology, the computer technology, the geographic information system technology, the database technology, Visual Basic 6．0 , MapX and Access develops the forest fire protection auxiliary decision system. This paper introduced domestic and foreign most recent development tendency of auxiliary decision system, the developing meaning, the route of technology, the result of the System; It analyses application system structure, GIS spatial database management and property database management and graphical user interface design, system design, function design which are the key application technology in the process of building system; puts emphasis on studying basic GIS, the monitor of forest fire, fireground loss estimation and the best route analysis which are the key parts of system; discusses development situation, experiment attestation as well as the existence problems and so on about the whole system in the entire research process ; points out the development direction of forest fire auxiliary decision system in the future.The System provides searching of the forest fire historical data and saving of the forest fire new data. The System provides stock map, fire risk map, the forest fire protection and so on. The System provides the whole course of monitor and auxiliary decision of fire suppression methors. The System provides the basic functions of GIS, which include zoomin, zoomout drag ,edit and so on. The System provides helping for the forest fire.
