Therefore, the prevention of winter wheat freezing injury should take more attention even under climate warming.

因此，虽然气候变暖，但冬小麦冻害防御仍不容忽视。

Currently, the basic method of monitor winter wheat freeze injury is concentrated on temperature retrieval and compared with NDVI before and after freeze injury.

当前冬小麦冻害遥感监测研究大多集中于反演地表温度或受灾前后归一化植被指数ND VI变化分析。

So the method of change vector analysis is effective for monitoring winter wheat freeze injury and growth recovery. Also it supply a new way to monitoring the other crop disaster.

因此，变化向量分析法能有效地监测冬小麦冻害灾情与灾后长势恢复情况，同时对其他作物灾害监测提供了途径。
