摘要:

根据山西省朔州市气象局1957~2009年气温、降水、初霜冻、终霜冻、无霜期、≥0℃和≥10℃积温等资料分析了朔州市近53 a来的气候变化。结果表明:朔州市年降水量呈下降趋势,气温则呈上升趋势。1998~2009年随着年平均气温的升高和降水的显著减少,初霜冻出现连续性明显偏晚;终霜冻出现偏早趋势,从1999~2009年,终霜冻出现时间稳定偏早。无霜冻期呈延长趋势,主要由于年代际平均气温升高使初霜冻日推迟和终霜冻日提前造成的;≥0℃和≥10℃活动积温呈现增加趋势。这些变化必将影响到农业生产的布局和结构。

Abstract:According to the data of temperature,precipitation,the beginning of frost,the end of frost,frost-free period,≥0℃and ≥10℃accumulated temperature from Shuozhou Meteorological Bureau in Shanxi Province during the period of 1957-2009,the climate change in Shuozhou city was analyzed.The results showed that the precipitation in Shuozhou decreased,but the temperature increased.Along with annual mean temperature’s increase and precipitation’s remarkable reduction during 1998-2009,the date for the beginning of frost was obviously postponed;and the date for the end of frost presented stable and early trend.The frost-free time presented prolonged tendency.The accumulated temperature of≥0℃and≥10℃presented increase trend.These changes will affect layout and structure of the local agricultural production.Key words:climatic change;precipitation;temperature;the date of beginning and end of frost;frost-free eriod;accumulated temperature;Shuozhou
