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.

TECHNOLOGIES IN REGIONAL FORECAST OF INSECT PEST |

Abstract: | Most insects destructive to agricultural crops and forests are highly mobile, and theirnumber and damage vary greatly in space and time. Their seasonal activity patterns and related dam-age rates also differ greatly from place to place and year to year. It is vital that we have the capabili-ty 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 col-lection and processing of information. Techniques used in regional forecast of insect pests were dis-cussed in the paper, including monitoring, modeling, information processing and disseminating. |
