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.

2建立了林火模型库建设的林火蔓延模型评价标准，根据模型评价标准和试验区实际情况，在42个林火蔓延模型中选择了目前最具有影响力和最具有典型代表性的Rothermel模型、王正非模型、加拿大模型和澳大利亚模型进行了解析和归一化处理；对林火模型库的建库过程和方法进行了研究，在林火模型分类基础上，采用面向对象的模型库表示方法建立了林火模型库；实现了林火蔓延模型算法，设计了模型字典库、模型文件库和模型知识库；开发了模型库管理与维护功能，实现了模型的文件管理、参数管理和知识管理；通过模型数据管理文件解决了模型库与数据库之间接口问题；实现了林火模型库对林火模型适宜性选择和林火模型自适应修正技术的有效支持。
