基于CRITIC权的减法集对势法在佛子岭水库汛期分期中的应用

深入了解集对分析在水库汛期分期应用，选取旬中暴雨日总数、旬多年平均雨量、旬中最大3天雨量、旬多年平均来水量、旬中年最大洪峰出现次数等5个指标，采用CRITIC赋权和模糊集对分析方法，构建了基于CRITIC权的减 法集对势汛期分期方法。以佛子岭水库为例，将佛子岭水库汛期划分为前汛期、主汛期、伏旱期和后汛期四个分期，最后与减法集对势法进行了对比分析。分析结果表明：基于CRITIC权减法集对势汛期分期法考虑了不同水文气象因素对汛期分期影响程度相对大小，汛期分期成果合理，为水库调度管理工作提供了参考依据。

Application of subtractive set pair potential method based on CRITIC weight in flood season stage of Foziling Reservoir

In-depth understanding of the application of set pair analysis in the flood season of reservoirs, select 5 indicators including the total number of heavy rain days in the middle of the ten days, the average rainfall in the ten years, the maximum three-day rainfall in the middle of the ten days, the average water inflow in the ten years, and the number of maximum flood peaks in the middle of the ten-day year. CRITIC based on the weighting and fuzzy set pair analysis method, a subtraction set pair method for staging flood season based on CRITIC weight is constructed. Taking Foziling Reservoir as an example, the flood season of Foziling Reservoir is divided into four periods: pre-flood season, main flood season, summer drought period, and post-flood season. Finally, a comparative analysis is made with the subtraction set pair potential method. The analysis results show that: based on the CRITIC weight subtraction method, the flood season staging method considers the relative influence of different hydrometeorological factors on the flood season staging, and the flood season staging results are reasonable, which provides a reference for reservoir scheduling and management.
