病虫的发生量是由许多因素综合影响的,有主要的、有次要的,“非关键因子”虽然不能决定病虫发生的程度,但许多这样的因素累积作用的结果,对发生量也有很大的影响,因此,准确的发生量预报必须考虑这些“非关键因子”的作用。 本文所介绍的模糊综合决策法是应用模糊数学对资料进行处理,通盘考虑诸因素权重分配,通过计算模糊关系矩阵求得各级发生频率,作出预报判断,计算简单,判断准确,比一般的数理统计具有明显的优点。
The occurrence of pests and diseases is influenced by many factors. There are major and minor “non-critical factors” that can not determine the degree of occurrence of pests and diseases. However, the cumulative effect of many of these factors is also significant for the occurrence Therefore, accurate prediction of the amount of occurrence must consider the role of these “non-critical factors.” In this paper, the fuzzy comprehensive decision-making method is the application of fuzzy mathematics to deal with the data, all factors considered by the weight distribution, by calculating the fuzzy relation matrix found the frequency of occurrence at all levels to make a forecast, the calculation is simple, accurate, more accurate than the average Statistics have obvious advantages.
