摘　　要：针对水库汛期具有确定性、随机性、过渡性的变化特征,结合汤河水库汛期洪水变化规律,在分析数理统计法、模糊集合分析法、层次聚类法的基本原理及各自优缺点的基础上,分别应用3种方法研究了汤河水库汛期分期规律。综合考虑3种方法分析结果及该水库原有汛期分期方案,确定汤河水库优化汛期分期方案为:6月1日～7月20日为前汛期;7月21日～8月20日为主汛期;8月21日～9月10日为后汛期。Flood has characteristics of determinacy,randomicity and transition.Based on the analysis of the basic principle of mathematics statistics,fuzzy set analysis,hierarchy cluster analysis and their advantages and disadvantages,the paper applies three methods to study the variation rule of stage flood period for Tanghe Reservoir.Considering the results of these methods and the original program of the reservoir,optimal stage flood period scheme of Tanghe Reservoir is obtained： the antecedent flood period is between June 1st and July 20th;the main flood period is between July 21st and August 20th;the post flood period is between August 21st and September 10th.
