摘　　要：以福建为例,以连旱日数为统计量,首先重建了单站春旱、夏旱和秋冬旱气象干旱历史序列;其次,采用百分位数法,建立了单站气象干旱强度定量化评估指标;最后,提出了基于单站气象干旱指数基础上的全省一定时段内气象干旱强度的定量化评估方法。与历史重大个例的比照,显示了该方法的合理性。Based on the statistical continuous drought days in Fujian, firstly, the drought meteorological drought historical sequence of a single station was rebuilt in spring and autumn winter; second, meteorological drought intensity quantitative evaluation index of a single station was established by the percentile method ; finally, the quantitative evaluation method of the provincial meteorological drought intensity within a certain period was proposed on the basis of the single station meteorological drought index. It shows the rationality of this method on the comparison with these important examples in history.
