摘要
以大面积、无损的农作物苗情监测为目标,采用GIS、RS、GPS等空间信息技术,结合计算机技术、网络技术设计开发了基于空间信息的农作物苗情监测系统。在前人研究基础上,筛选了能够表征作物长势、产量和品质的农学参量及遥感植被指数,提供自定义监测预报模型的方式实现对农作物长势、产量及品质监测。最终,以2012年北京地区冬小麦长势监测为例,展示了农作物长势分析过程,获得了同实际情况相吻合的监测结果。
Abstract： For the target of large scaled, non-destructive crop monitoring, this study was to design and develop the spatial information support systems for monitoring crop. It was based on spatial information technology which mainly about GIS, RS and GPS, and combined with computer technology and network technology. The system characterized the agronomy of the crop growth, yield and quality parameters, and filtered remote sensing vegetation indexes. Then the system provided the self-defined model function for crop growth monitoring, yield prediction, quality diagnosis on the basis of previous studies. Finally, the system presented the analysis of crop growth on the test of wheat growing data in Beijing 2012, and the result was consistent with the actual ground measurement data. Key words：crop; growth and seeding monitoring; spatial information
