Abstract: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.
