作物冷冻害遥感监测研究进展

he frequency and intensity of extreme weather are appearing the great change on the current global climate events, disaster losses are increasing. Among them, chilling and freeze injury is one of the common disasters for crops. Real-time monitoring of crop disasters is extremely concerned by related departments including agricultural departments and local governments. Development of remote sensing techniques provides a fast, non-destructive, large area means of detection for monitoring and forecasting crop chilling and freeze injury. This paper reviewed major advances in monitoring and forecasting the crop chilling and freeze injury by using remote sensing, and summarized the main techniques for monitoring crop chilling and freeze injury using remote sensing. On the basis, the difficulties about the technology of remote sensing monitoring crops chilling and freeze injury were analyzed and prospected.
