山西省东亚飞蝗发生的灰色动态预测及其周期分析
The grey dynamical prediction and periodical analysis on Locusta migratoria manilensis(Meyen.)in Shanxi province
【摘要】 采用灰色系统理论与方法 ,建立山西省东亚飞蝗的灰色动态预测模型 ,并通过残差周期分析提高了模型的精度 ,对未来 10年山西省东亚飞蝗的发生情况做出预测 ,为其防治提供可靠的科学依据。图 2 ,表 7,参 7。
【Abstract】 In this paper, models of grey dynamical prediction on Locusta migratoria manilensis(Meyen.)in Shanxi province were established, prediction results showed that the outbreak period of locusts was approximately 6 to 7 years. Around the year of 2004 or 2005, a very serious locusts plague would take place in Yuncheng, Shanxi in accordance with the opinions of the paper.
