利用廊坊北部1980-2013年的逐日气温观测资料，分析了冬小麦易发生冻害时期的平均气温、极端气温、负积温和温度波动的特征及变化趋势。结果表明，在气候变暖的条件下，廊坊北部麦区越冬前和越冬期的平均气温、极端气温、负积温均呈现上升趋势，其中越冬期的平均气温、最低气温上升明显；越冬期最大降温幅度逐年变化幅度较大，但近34a来没有明显的增减趋势。

This paper analyzed features and changing trend of average temperature, extreme temperature, negative accumulated temperature and temperature fluctuations of winter wheat when prone to freeze injury using the observation data of temperature in north of Langfang from 1980 to 2013. The results showed that the average temperature, extreme temperature and negative accumulated temperature showed a rising trend before overwintering and overwintering period in north of Langfang wheat region under global warm?ing. The average temperature and minimum temperature increased significantly when overwintering period. The maximum temperature decline range presented great changes year by year in overwintering period,but had no obvious variation trend for recent 34 years.
