摘　　要：根据陈守煜建立的模糊水文学原理 ,提出用直接模糊统计试验确定汛期相对隶属函数 ,对我国北方和西北缺水地区龙凤山水库、冯家山水库进行了汛期直接模糊统计试验 ,得到汛期相对隶属函数 ,并进行了稳定性分析 .在稳定性论证的基础上 ,得到当资料年限足够长时 ,汛期相对隶属函数可近似地作为汛期绝对隶属函数 ,为研究水库不同设计洪水标准下汛限水位的动态控制提供理论依据 .Based on CHEN Shouyu's fuzzy hydrological theory, a method was developed for determination of the relative dependence function by the direct fuzzy statistic test. By fuzzy statistic tests performed for the flood season of the Longfengshan Reservoir and Fengjiashan Reservoir in water-deficient regions in north and west China, a relative dependence function of flood season was determined, and its stability was analyzed. It is concluded that with sufficient long-term data, the relative dependence function of flood season can approximately be taken as the absolute dependence function, providing a theoretical basis for dynamic control of reservoir water levels in flood season under different reservoir design standards.
