Study on flood spreading model of Hongze Lake based on cellular automata;

Research on two categories of spread model commonly used for forest fire;

In the new spread model for forest fire, bitmaps are operated and outlines of images are searched at the basis of the metagraphic set of fire-area shapes and the gray level image for spread calculation.

Two spread models frequently used for forest fire simulation,namely the contiguous cellular model and the wave propagation model,strongly complement each other in their advantages and disadvantages,this is utilized in this paper to design a spread model based on computer graphic techniques,assimilating the advantages of the former on the basis of the latter.

Several popular fire spread models were described.

In order to increase the accuracy and the widely use of fire spreading model,the paper base on the change state of temperature of the calculus on fire area,use the law of energy conservation,it can give the change of the temperature field s Mathematical model on the fire area.

Selecting forest fire spreading models based on the Fuzzy Data Mining technique.;

The key point of this paper is to establish the technology system of acquiring remote sensing data, polising data,processing data,establishing forest fire spreading model and simulating the spreading model with the modern survey technology,to provide data support for the forest fire police based on the established fire spreading model.
