| 摘 要： | 根据1956～2007年山西省运城市的降水资料和美国观测站公布的太阳黑子活动周期的观测资料,在用Z指数对降水资料进行处理而确定旱涝等级和年份后,对太阳黑子活动周期与运城市旱涝年的相关关系进行了分析。发现运城市涝灾主要发生在太阳黑子周期的极大值年及其后第3年,旱灾则在太阳黑子周期的极值年及前后1～2年内都有可能发生。

| Abstract: | According to the precipitation data from 1956 to 2007 of Yuncheng city in Shanxi province and the sunspot activity cycle data came from U.S.A.,after using Z-index to dispose the precipitation data and determine the levels and years of drought and flood disaster,the author conducted a preliminary analysis on the relationship between the drought and flood disaster years of this city and the sunspot cycles.It was found that there was close correlation between the years of drought and flood disaster in Yuncheng city and the 11-year sunspot cycle,waterlogging disaster mainly occurred in the peak year and the third year after the peak year of sunspot cycle,while drought disaster was likely to occur in the peak year and 1～2 years before or after the peak year of sunspot cycle. |
