Grid Based Aidded-Decision Model For The Forest Fire Prevention

The forest resources' continuous and stable development is the focus of the countries' attention all over the world, and the defense and control of forest fire are also given more attentions. Along with the information technology's effect upon the daily business which is for the prevention of forest fire became more and more remarkable, the forest fire prevention aided-decision system already became the essential tool in the daily forest fire prevention work. Therefore, the forest fire prevention organization must unceasingly use the new technology to research and develop the forest fire prevention aided-decision system which is more suitable for its own services' request, strengthen the information sharing and the cooperation abilities, enhance the efficiency of work, adapt the forest fire prevention works' requests in the information era, serve for the forest fire prevention routine work better.This paper take the work "Oriented-Digital Forestry Application software Key Technology Research" as the background which was supported by a grant from the key science and technology program of Heilongjiang Province, under the research background of digital forestry, the emerging grid technology will be introduced to the forest fire protection special study, according to actual situation, construct aided-decision system model for the forest fire prevention with the idea of oriented service, which devote to overcomes problems which exist in aided-decision system such as limit to resources sharing, back of the cooperation ability, costly for the system development, complexity of the maintenance. The main research contents of the article are as follows:(1) Set forth the background and the significance that the thesis studies, take current situation of Ta He county Forestry Administration in Heilongjiang province'fire prevention as point of penetration, analyze the requirements of function and data processing which is needed by fire prevention, find out the shortcomings and deficiencies which lie in the more successful forest fire prevention system, brought up the grid to solve these problems.(2) Gather materials on grid then study the grid and its recent developing achievements, analyzes and compares the grid with Service-Oriented Architecture(SOA). Study and research the fundamental technology such as OGSA, Web Service and Globus Toolkits version four (GT4), grasp the relationship between them, which aim to put down solid fund of building the model of the forest fire prevention aided-decision system.(3) Integrate grid into the forest fire prevention aided-decision system, and structure the model based on grid of the forest fire prevention aided-decision system. Focus its keys on architecture and each level's building method and operating mechanism, emphasis on interpreting mechanism of spatial data sharing and expert system based on grid's working theorem.(4) Probe deeply into the supporting environment of software and hardware and its system secure aspect's configuration. Finally the article proposals a common method to build web services, and take drawing up a scheme to put out the forest fire as an example, explain the general procedures for Forest Fire Prevention Grid Decision Support System (FFP-GDSS) working.At present using the grid technology in forestry domain is at the start stage research, it does not have successful model, therefore this research is a foresightedness attempt, a guide of study and an exploration.
