GIS技术在农作物病虫害监测预警系统中的应用

Application of GIS used in the crop pest monitoring and forecasting system

对当前我国地理信息系统(Geographic Information System,GIS)技术在农作物病虫害监测预警系统中的应用现状进行了分析,概括了其随着GIS技术的发展从基于桌面GIS到基于WEBGIS的发展轨迹,以及GIS技术在农作物监测预警系统中的主要应用,总结现有基于GIS的农作物病虫害监测预警系统存在的问题与不足。结合当前信息技术的发展,对今后基于GIS技术的农作物监测预警系统的发展进行了展望。

The paper analysed the current situation of GIS application in crop pest monitoring and forecasting system in our country, and summarized the progression course of this type system developing from based on desktop GIS to WEBGIS and the main application of GIS in crop pest monitoring and forecasting system. The paper also concluded the problems and faults existed in current crop pest monitoring and forecasting system based on GIS. Combing with the development of present information technology, we gave some expectation to the development of the crop pest monitoring and forecasting system based on GIS.
