摘  要:
利用赤峰地区1951-2006年的气温、降水、沙尘暴等资料,分析了赤峰地区近50 a来的气候变化趋势,探讨了气候变暖带来的影响。结果表明:赤峰地区20世纪80年代以来气候变暖已成事实,1987年是气候变暖的突变时间点。气候变暖后,低温日数明显减少;无霜期延长,积温增加;旱涝和降水异常天气现象发生的概率增大;大风和沙尘暴发生概率减少。分析认为:气候变暖对赤峰地区农业的影响是利大于弊,而对生态环境的影响则是弊多利少。

摘  要:
Based on the data of the surface air temperature,precipitation and sand-dust storm from 1951 to 2006 in Chifeng,the trend of the climate variation in Chifeng during the last 50 years was analysed and the impacts of the climate warming was studied.The result showed that the climate warming had been observed since 1980s in Chifeng.It was the key year of the climate sudden change in 1987.The days with low surface air temperature were obviously less than before.The frostless season prolonged.The accumulated surface air temperature increased.The probability of the extreme weather events,such as the drought or flood and precipitation anomalies increased.The probability of strong wind and sand-dust storm decreased.It was concluded that the impacts of the climate warming on agriculture were more advantageous than disadvantageous,but contrarily on ecological systems.
