摘要
用直接方法（解析法）和间接方法（模拟法）对多年持续干旱历时的概率分布进行了分析，提出了一种确定多年持续干旱历时重现期的方法——全历时重现期法。该方法概念明确，便于实用。
In this paper the direct approach (analytical method ) and indirect approach ( simulating method) are applied to analyze the probability distribution of durations or lengths of persistent multi-year droughts.Meanwhile a method for determining retutn p0eriods of the droughts is proposed so callde as the method of entire duration retutn pdriod.It is convenient to use the method in practice.
