摘要
The monthly maximum precipitation in the Niangziguan Spring Basin is studied in light of the General Pareto Distribution (GPD) model.In order to get the interrelations between the extreme precipitation and the spring discharge,the relationship between the mean annual discharge and the maximum monthly precipitation at different recurrence intervals are analyzed on the basis of eliminating the decreasing trend of the spring discharge caused by human activities.The results show that there is a two-year time lag between the maximum monthly precipitation and the mean annual discharge.Moreover,the quantitative relation expression between the maximum monthly precipitation and the mean annual discharge is put forth in this paper.
