模糊推理在热带作物病虫害诊断系统中的应用

摘要

In order for the application of fuzzy reasoning in tropical agriculture disease and pest diagnosis,on one hand we need to take into account the diversity of symptoms and species of disease and pest , on the other hand we need to give consideration to the uniqueness of symptoms. Expert system stores weighting index in the database, then calculate index in the module way. According to the threshold of disease and pest symptoms, screening the symptoms information of the user, calculating the similarity of symptoms with weighted algorithm, finally obtains the accurate results.%将模糊推理应用到热带作物病虫害诊断系统中,既要考虑热带作物病虫害种类及其为害症状的多样性,又要兼顾每一种病虫害为害症状的独特性.热带作物病虫害诊断系统将权重指数存储在数据库,然后以模块的方式对指数进行公式运算,同时根据病虫害症状的阀值,筛选用户提出的症状信息,选用加权算法计算症状相似性,最终得出准确的结果.
