| 摘 要： | 根据宁夏同心县1951—2006年的气温和降水记录,用相关分析、统计和回归等数理统计方法进行了分析,表明56年来同心县气温有明显上升的趋势,年平均气温呈线性升高,冬季升温幅度最大、夏季微弱是气温变化的主要特征.降水量的变化不明显,但秋季降水有减少的趋势.56年来同心县呈现凉湿—凉干—暖湿—暖干的变化趋势.

| Abstract: | The climate changes in Tongxin County of Ningxia were analyzed by the methods of correlation analysis,statistics and regression based on the records of atmospheric temperatures and precipitations from 1951 to 2006.The results showed that the atmospheric temperature ascended remarkably and the annual mean temperatures increased significantly during recent 56 years with the characteristics of great increase of atmospheric temperature in winter and little the increase of atmospheric temperature in summer.The changes of precipitations were not obvious with reducing precipitations in autumn.There was a distinct trend for climate changes from cool wet to cool dry to warm wet to warm dry. |
