The four models were analyzed and normalized. We studied the procedure and method of building forest fire model base. Model base was build by object-oriented method based on category of model. Forest fire spreading models algorithm were implemented. We designed model dictionary base, model file base, and model knowledge base. Model base administration and maintenance functions were developed and implemented model file management, parameter management and knowledge management. The problems of interface between of model base and database were solved by means of model data control files. Model base ensured the availability of supporting for forest fire model suitability selection technology and forest fire model self-adapting updating technology.(3) Based on BP artificial neural network, we designed a frame construction of forest fire model selection of suitability. Forest fire model selection knowledge was produced through BP artificial neural network.
