摘要
[目的]分析1954～2010年邢台市气候特征。[方法]根据邢台市1954～2010年的气候资料,利用折线图、趋势图、气候变率及统计图表,对邢台市57年来气候特征进行具体分析。[结果]1954～2010年邢台市年平均气温、年平均最高和最低气温均呈现出逐渐上升的趋势。其中,年平均最高气温的上升速率最慢,年平均气温呈现出逐年升高的趋势,年平均最低气温的升高速率最快。年平均降雨量、风速、相对湿度、日照时数均呈现出逐步降低趋势;年平均总云量呈增加趋势。1954～2010年邢台市0、5、10、15和20 cm的年平均地温分别为15.6、15.7、15.8、15.8和15.8℃。1981～2010年邢台市40和80 cm、1.6和3.2 m的年平均地温分别为15.2、15.2、15.4和15.4℃。可见,深层地温随深度的增加而逐渐升高。[结论]该研究为指导邢台市农业生产提供了理论依据。
[Objective] The research aimed to analyze climate characteristics in Xingtai City during 1954-2010.[Method] Based on climate data in Xingtai City during 1954-2010,by using line chart,trend chart,climate variability and statistical diagram,the climate characteristics in Xingtai City in 57 years were analyzed.[Result] The annual average temperature,annual average maximum and minimum temperatures in Xingtai City during 1954-2010 all presented gradual rise trend.The rise velocity of annual average maximum temperature was the slowest.The annual average temperature presented rise trend year by year.The rise velocity of annual average minimum temperature was the quickest.The annual average rainfall,wind speed,relative humidity and sunshine hours all presented gradual decline trend,while the annual average total cloud amount presented increase trend.The annual average ground temperatures at 0,5,10,15 and 20 cm in Xingtai City during 1954-2010 were respectively 15.6,15.7,15.8,15.8 and 15.8 ℃.The annual average ground temperatures at 40 and 80 cm,1.6 and 3.2 m in Xingtai City during 1981-2010 were respectively 15.2,15.2,15.4 and 15.4 ℃.It was clear that the ground temperature at deep layer gradually rose as depth increase.[Conclusion] The research provided theoretical basis for guiding agricultural production in Xingtai City.
