Abstract: Now in China agriculture,remote sensing technique is applying in many studies, such as the monitoring and protection of agricultural field, the estimation of yield in large area crop, the monitoring of crop growth, the monitoring of agricultural and meteorologic disaster, the crop simulation model and so on. In this paper, the studies and applications mentioned above were discussed, analysed and evaluated. The development direction of agriculture remote sensing in studies is the technique of 3S integration, the forecast of disaster, hyperspectrual remote sensing, ration remote sensing and so on. At the same time, the application and development of remote sensing technology play an very important role in the boosting of Chinese digital agriculture process.
