摘　　要：本文根据运东闸站1964~2015年降水量资料,分析降水年内、年际变化规律,采用游程理论分析连丰连枯规律并利用Mann-Kendall检验法对降水发展趋势作出预测。结果表明,运东闸站降水量年内分配不均且主要集中在汛期,年降水量变化幅度大,丰、枯交替出现,年降水量呈现增加趋势,但趋势并不明显。Based on the precipitation data from Yundong sluice station in 1964-2015, the annual and inter- annual variation regularities of annual precipitation are analyzed. The runoff theory is used to analyze the high low regularity and the trend of precipitation is predicted by Mann-Kendall test. The results show that the annual precipitation of Yundong sluice station is uneven and mainly concentrates in the flood season, the annual precipitation change is large, the precipitation is alternated, the annual precipitation is increasing, but the trend is not obvious.
