摘要
通过对积雪和温度变化状况等的分析,研究了2008年雪灾对越冬作物的可能的影响。分析表明,雪灾过程中由于雪被覆盖,地表温度维持较高水平,对作物的越冬不会造成严重影响;融雪后期由于融雪耗能等因素,出现短暂极端低温,对油菜有一定不利影响,对冬小麦则影响很小。
Through the analysis on the status of snow cover and temperature changes,effects of snow disaster on overwintering crops in 2008 were studied.Result showed that due to the snow cover and the relative high level of land surface temperature,the overwintering of crop was not affected.Transient extremely low temperature appeared as a result of thaw,energy consumption and other factors,which caused a certain adverse effect on rape but had little effect on winter wheat.
