摘要：

稻飞虱是影响福建水稻生产的主要害虫，其发生发展与气象条件关系密切。本文基于统计学方法对福建省21个县晚稻稻飞虱发生等级与温湿、降水和日照条件等进行了统计分析，找出关键性因子，并建立了晚稻稻飞虱气象等级的经验统计模型。通过历史回代检验，各地区晚稻稻飞虱气象等级与实际发生的等级相比，各地区“一致”和“基本一致”的可达到50%～96%，总体预报效果较好，可投入业务应用。

Abstract:

Rice Plant Hopper is one of the main pests in the rice production in Fujian Province and its occurrence is closely correlated to the meteorological conditions．Based on statistical methods, the relation between the occurrence levels of late rice plant hopper and meteorological factors in twenty-one counties was analyzed. The factors included temperature, humidity, precipitation and sunshine hours. The experiential statistical model for the meteorological grade was established based on the key meteorological factors. The validation results by the historical test showed that the forecast accuracy can be reached from 50% to 96% by comparing meteorological grade with actual grade in each region. The forecast effect was good and the model could be put into operational application.
