摘　　要：利用1961~2021年阜新市春播期降水资料,分析了春播期降水变化特征。结果表明,1961~2021年阜新市春季降水量呈增加趋势,首场透雨的降水量呈减少趋势。4月上旬到6月中旬各旬平均降水量呈增加趋势。首场透雨降水量有准48年和准31年的周期,春季降水量有准62年和准36年的周期。阜新市历年春季降水占全年降水的15.9%,明显偏少。太阳黑子平均数与同期5月份降水量呈反相关关系,r=-0.257(P=0.046)。Based on the precipitation data during spring sowing in Fuxin from 1961 to 2021,the characteristics of precipitation change during spring sowing were analyzed.The results show that the precipitation of Fuxin city in spring from 1961 to 2021 shows an increasing trend,while the precipitation of the first soaking rain shows a decreasing trend.The average precipitation of each ten day period from the first ten day of April to the middle of June shows an increasing trend.The first pervious precipitation has a quasi 48 year and quasi 31 year cycle,and the spring precipitation has a quasi 62 year and quasi 36 year cycle.The spring precipitation in Fuxin over the years accounts for 15.9%of the annual precipitation,which is obviously less.The average number of sunspots is inversely related to the precipitation in May of the same period,r=-0.257(P=0.046).
