摘　　要：本文利用1953—1977年北极海冰覆盖面积和洞庭湖平原初夏降水量资料,通过交叉相关函数的计算,发现10月北太平洋—北冰洋海冰面积变化与洞庭湖6月降水量成正相关,相关系数为+0.4882,通过信度α=0.05的检验。By using the data of early summer rainfall and the monthly Arctic ice area during 1953-1977, we calculated the cross-correlation for both, and found that there is an apparent positive correlation relationship between the early summer rainfall over Dong-Ting Lake and the monthly Arctic ice area in North Pacific-Arctic in October for the last year. The correlation coefficient is equal to +0.4882 and degree of confidence is 0.05.
