集成GIS和RS技术的作物病虫害监测预报研究进展

Progress and application of integrating GIS and RS technology to monitor and forecast crop diseases and pests

为了保障农产品质量安全,在信息技术的推动下,作物病虫害的监测预报已发展到运用遥感(RS,Remote Sensing)和地理信息系统(GIS,Geographic Information System)集成技术,实时、客观、快速及大面积地监测预报作物病虫害的空间分布、发生状况,并适时为病虫害防治提供信息服务的阶段。文章分析了RS与GIS监测预报病虫害原理,在此基础上重点对国内外RS和GIS技术集成的病虫害监测预报方法、数据选择及处理、地面试验设计和精度验证的研究现状进行总结,并对今后的发展趋势作进一步的展望。

To guarantee the agricultural products quality safety,with the promotion of information technology, monitoring and forecasting crop diseases and pests is developed to the level of using technology of remote sensing(RS) and geographic information system(GIS)to get the real-time spatial distribution and status information of crop diseases and pests objectively and rapidly in a large area,and to acquire prevention information for crop diseases and pests timely. The principles of monitoring and forecasting diseases and pests integrating RS and GIS were discussed.Furthermore, emphases were given to summarize domestic and overseas RS and GIS technologies which were employed to monitor and forecast crop diseases and pests,and the methods for data selecting and processing,field experiments designing,data validation,etc.Finally,the prospect in this field was presented.
