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。
Based on the characteristics of uncertainty, randomness and transition in the flood season, combined with the variation of flood in flood season of Tanghe Reservoir, based on the analysis of the basic principles of mathematical statistics, fuzzy set analysis and hierarchical clustering and their respective advantages and disadvantages , Respectively, the application of three kinds of methods to study the Tanghe Reservoir flood season staging rules. Considering the analysis results of the three methods and the staging scheme of the original flood season of the reservoir, the plan of optimizing the flood season of Tanghe Reservoir is as follows: the first flood season from June 1 to July 20; and the main flood season from July 21 to August 20 Flood season; August 21 ~ September 10 for the flood season.
