摘要
植物病害数值诊断法是运用模糊数学原理和灰色系统理论，将植物病害症状信息用隶属度或灰度进行量化为诊断指数，在诊断中用模糊识别，经简单加减运算求和，以和值最大者为诊断结果。此法具有简便易于掌握，快速诊断准确率高的特点，是植物病害诊断与模糊数学、灰色系统理论、信息论等新学科相结合的一种新方法。
The quantitative diagnostics for plants diseases,which based on the theory of Fuzzy mathematics and Grey systems,deals the information of diseases symptoms with Degree of confidence or Grey Scale and quantifies them into diagnostics index number.In pruetice it uses Fuzzy recognition,gets the result through simple calculation,which is the maximum of all results.This way is quick,simple and also has the high accuracy.The quantitative diagnostics combines the diseases dignosis for plants with new sciences such as Fuzzy mathematics,the theory of Grey Systems and Information Theory.
