摘 要：
利用无定河流域14个气象台站1970-2004年的4-9月的降水资料,应用负轮理论对流域气象干旱进行了研究。结论表明,无定河流域各站丰枯变化趋势基本一致;以少水状态的频率出现最多;流域负轮周期以3、4年居多。

摘 要：
Making use of the precipitation data in April to September from 1970 to 2004 of 14 meteorological stations of Wuding River basin,the meteorological drought is analyzed by using displacement theory.It is concluded that the change trend of ample and low precipitation of each station keep consistent,the low precipitation occurs the most frequently,and the displacement cycle of 3 years and 4 years accounted for the most.
