摘要
本文简介了“全球农情遥感速报系统”的基本情况,包括作物长势监测、主要作物产量预测、粮食产量预测、时空结构监测和粮食供需平衡预警等五个子系统。具体介绍了该系统提供的信息产品的应用,包括国内外农作物长势监测、作物和粮食产量估算、种植结构监测、复种指数监测以及旱情监测等内容;同时就系统应用时存在的问题提出了建议。
We introduce the 5 components of China Crop Watch System with Remote Sensing in the paper. They are Crop growth status monitoring system, Main crop production predication system, Grain production predication system, Crop temporal and spatial structure monitoring system and Grain balance and early warning system.The information productions of CCWS include Chinese crop growth status monitoring, crop and grain production predication, crop spatial structure monitoring, cropping index monitoring and drought condition monitoring. From 1998 to 2003, CCWS monitoring area has expanded from east china to all over china, to North America and South America, to Australia and Thailand. we propose to Chinese government to integrate the methods of crop watch with RS which come from the efforts of Chinese scientists in last decades, and to built the world crop production monitoring system with remote sensing.
