| 摘 要： | 利用且末绿洲近50 a初、终霜日等气候资料,分析该地区的霜冻变化特征,初步探讨其对主要农作物的影响.结果表明:且末绿洲近50 a来终霜危害大于初霜,初霜冻推迟、终霜冻提前趋势明显,无霜期呈微弱延长趋势但不显著；初、终霜均具有5a、33 a的振荡周期,未来一段时期均处在偏晚期；进入21世纪以后未出现特早初霜和特晚终霜.总体上看,气候变暖使该地区霜冻灾害减少,对主要农作物的生长有利.

| Abstract: | Based on the first frost and last frost meteorological data in recent 50 years of Qiemo Oasis,analyzed the change characteristics of frost and discussed the influence to the main crops in the region. The results indicated that the last frost did more harm than first frost in past 50 years,the trend of delaying first frost and advancing the last frost was obvious, while the frostless period was shorten little.The first frost and last frost existed the oscillation period of 5a and 33a and the trend of partial late in the future. The special early first frost and late last frost did not appear in the 21st century.On the whole,the climate warming mitigated the frost disaster,which was very favorable for the growth of main crops. |
