本文论述了害虫经济阈位(ET)和经济为害水平(EIL)的概念与争鸣,并讨论了 EIL 的模型及其建模原理,作者提出了一个动态的 EIL 模型:作者认为经济阈值(ET)应在危害边界(DB)与经济为害水平(EIL)之间,在确定了 DB 与 EIL 之后,作者第一次嚐试用模糊综合评判的方法来制定害虫的经济阀值(ET)。
This paper discusses the conceptions and contention of pest economic threshold (ET) and economic harm level (EIL), and discusses the EIL model and its modeling principle. The author presents a dynamic EIL model: the author believes that economic threshold (ET) It should be between the hazard boundary (DB) and the economic damage level (EIL). After determining the DB and EIL, the author attempts for the first time to establish the economic threshold (ET) for pests using fuzzy comprehensive evaluation.
