Study On Forest Fire Forecast System In Beijing XiShan Forest Farm

This study was carried out on the current domestic and international forest fire forecasting technology and the summary of development trends, combines with the project development of "Beijing XiShan forest farm fire management information system", bases on the investigation and analysis of meteorological forestry, forest resources, and human activities such as forest fires archive data, aims at the frequent human activities of the outskirts of urban forestry, selects fire predictors scientifically, builts a forest fire forecasting evaluation index system constitutes by the weather, combustible resources, terrain, and other human activities such kind of factors. The paper uses integrated indicators scoring for the establishment of forest fire risk prediction model. According to experts research, log fire (including meteorological, fires and other data), and the distribution of vegetation and human activities data, by using Excel VBA program, the author builts a model simulation platform, after many tests, confirms the various parameters of the fire danger rating prediction model.On the basis of the above model, the paper uses GIS technology components to analysis, design and implementation of forest fire forecast system. It includes: meteorological data and data resources, human activities, such as the model parameters maintenance and management; fire forecasting calculation; fire forecasting output modules. To the end, through the collection, collation, the importation of all types of data, the author updates the forest resources, human activities such as the building of spatial database. System will not only provides daily forest fire forecast and its thematicmap, but also provides human activities, combustible materials thematic maps to identify key forest fire region, forestry departments to formulate specific prevention measures on provided scientific basis. The system function is practical, interface is friendly and easy to operate, and fire management to junior officers to use and promotion.
