摘　　要：利用辽宁省1956~2018年的降水量和太阳黑子相对数资料分析了辽宁西部、中北部、东南部地区夏季降水量与太阳黑子相对数的关系。结果表明:(1)1960年代以来,辽宁省中北部和东南部夏季降水量距平系列变化过程相似,西部地区与它们相比,在1980年代中期和2010~2013年有一定差异。三个区域的降水量距平系列均为减小趋势,但只有东南部的趋势达到0.05显著水平。(2)太阳黑子相对数序列与西部、中北部、东南部地区夏季降水量序列呈显著负相关。(3)从多年平均来看,西部、中北部、东南部地区夏季降水量的极大值多在太阳活动的极小年(m年)及其前后;各分区夏季降水量极小值多分布在M年及其前后。The relationship between relative sunspot number and summer precipitation in western,mid-northern and southeastern parts of Liaoning Province was analyzed based precipitation and relative sunspot number data from 1956 to 2018.The results indi-cate that(1)since 1960s,the anomalies of summer precipitation in mid-northern and southeastern Liaoning Province are similar,while the western Liaoning behaved differently in middle 1980s and during 2010-2013;(2)relative sunspot number and the sum-mer precipitation in western,mid-northern,and southeastern Liaoning Province were negatively correlated significantly;(3)according to the long-time average annual values,the local maximum of summer precipitation in the three areas occurs around m years,on the other hand,local minimum of summer precipitation tends to occur around M year.
