The Research Of Assistant Decision-Making System In Forest Fireproofing On County Level In Zhejiang Province

In recent years, with the development of computer technology, the application of GIS technology in forest fire management has been receiving increasing attention. According to the require of forest fireproofing work, a powerful GIS ability of spatial analysis and positioning and the multi-dimensional information processing method to forecast fire insurance rating, remote monitor fire, simulating the forest fire spread, fire losses estimation, and so on, to make the forest fireproofing work more scientific and information.Forest fire spread is an extremely complex burning and movement phenomenon which a multi-phase, multi-component combustible under the influence of variety weather conditions and terrains. There are many factors which affect forest fire spread, the parameters of factor are complex as well, the computing of mathematical model are also, hence, it is inevitable to build a suitable forest fore spread model for computer simulating. On the basis of forest fire spread simulation, according to current fire situation and tendency, road traffic, fire fighting resources distribution, water distribution, etc, to estimate the prioritized collocation of fire fighters and facilities, display them in chart forms. According to these analyses to generate fire fighting plan as reference for the decision-makers. In the light of forest fire, forest distribution and species composition, using the spatial fold function to obtain the areas of different forests, finally with the corresponding economic value coefficient, the economic loss could be assessed, as well as to assess the corresponding environment loss.This paper provides the accessorial methods and techniques for fireproofing and fighting, is based on the research in the appearance and the development of forest fire. According to the actual situation, has used the integrated model which WangZhengfei forest fire spread model and GIS technology, on the basis of the computer simulation and prediction of forest fire spread, carried out the best path analysis, dispatch the fire fighting materials, command the forest fire fighting, fire losses estimation, displays the results in chart from, provides the decision-making support for fire fighting.
