| 摘 要： | 大多数农作物害虫都是高度活动的，它们的数量和造成的为害在时间和空间上都大不一样，季节活动型和造成的为害率也因地域和年份而异。要预测害虫在一个区域范围的出现，数量，种群趋势和潜在为害，就要建立完善的监测体系，多年定点观测记录对于区域害虫预测来说是最基本的资料条件，与此同时，通过数学方法把害虫的发生与相关因子以数量化的形式表示出来，并在此基础上建立中长期预测模型是至关重要的，为了及时处理和传递虫情信息，计算机数据管理技术和网络技术将为此提供最重要的技术支撑。本文通过一些典型的应用实例，讨论了监测技术，预测模型。GIS技术，数据管理技术以及网络技术在区域害虫预测中的应用。

| Abstract: | Most insects destructive to agricultural crops and forests are highly mobile, and their number and damage vary greatly in space and time. Their seasonal activity patterns and related damage rates also differ greatly from place to place and year to year. It is vital that we have the capability to anticipate and forecast their occurrence, abundance, population trends, and potential damage.This predictive capability must have a sound biological and ecological basis and be based on the collection and processing of information. Techniques used in regional forecast of insect pests were discussed in the paper, including monitoring, modeling, information processing and disseminating. |
