摘　　要：二叉分类检索表作为一种基本数据结构,被广泛地应用于病虫分类鉴定.为了能更灵活地应用二叉分类检索表作为知识推理进行病虫分类鉴定,提出在常规推理的基础上,融入反向推理和混合推理技术,将二叉分类检索表作为知识装入专家系统知识库,计算机可以利用它搜索分支结点以实现病虫辅助鉴定.开发研制出的病虫害辅助分类鉴定专家系统,可以实现系统的多元化功能,能满足用户多方面的需求.The binary classification key, a kind of basic data structure is widely applied in the taxonomic identification of diseases and pests. For the sake of using the binary classification key more flexiblly to classify and identify the diseases and pests as knowledge reasoning, the integration of the principles of backward reasoning and two-way reasoning was put forward, which charges the binary key into the knowledge database of expert system, and computers can make use of the structure to search the branch node and realize the assistant identification of diseases and pests. The assistant expert system developed for diseases and pests identification and taxonomic study can carry out the diversified functions of the .system, and meet various requests of users.
