| 摘 要： | 利用1957～2007年的降水资料,分析总结了蚌埠市近50年来的降水变化特征.结果表明:蚌埠市自20世纪中叶以来降水量呈明显增加趋势,春季降水呈"正常-少-多-持续偏少"的变化趋势,夏季呈"多-少-持续偏多"的变化趋势,秋季呈"少-多-持续偏少"的变化趋势,冬季呈"正常-少-正常-少-持续偏多"的变化趋势.近50年中蚌埠少雨年多于多雨年,降水多寡不均,旱涝灾害发生频繁.

| Abstract: | Based on the precipitation materials of Bengbu City trom 1957-200/,the preclpltahonal character is statistically analyzed. The results show that Bengbu has had noticeable increases in precipitation since the mid-20th century. The precipitation change tendency of the spring is ＂normal-little-much-continuous little＂ , that of the summer is ＂much-little-continuous much＂, that of autumn is ＂little-much-continuous little＂, and that of the winter is ＂normal-few-normal-few-continuous much＂. The years of wetness have been more than years of drought in recent 50 years of Bengbu,and the precipitation is so uneven that drought and flood disasters occur frequently. |
