【摘要】：针对水库汛期具有确定性、随机性、模糊性和过渡性的变化特征,在综合分析传统汛期分析方法和指标的基础上,结合可变集理论,提出了基于量变与质变判别模式的汛期分期原理与模型,研究了基于暴雨指标、洪水指标和综合指标的水库汛期分期的变化规律,结果表明分期结果能反映指标的物理意义,有较强的理论背景,数学概念清楚;且汛期分期结果与分期指标有密切关系,在实际应用应综合考虑多种指标,让分期结果更客观,同时也可以利用不同指标的分期结果,为防洪安全或挖掘洪水资源潜力提供技术支撑.
[Abstract]:In view of the reservoir flood season has uncertainty, randomness, fuzziness and transitional characteristics, analysis methods and indicators in comprehensive analysis of traditional flood season, combined with variable set theory, put forward the quantitative and qualitative discriminant model and the model based on the principle of flood period, based on the variation of flood season rainstorm index, comprehensive index and reservoir flood the results show that the index of staging, staging results can reflect the physical meaning of the index, there are strong theoretical background, mathematical concepts clear; and the result of flood season staging has close relationship with the staging index, considering the variety of indicators should be in the practical application, make the staging result more objective and staging results also can use different indicators, provide technical support for the safety of flood control flood or mining resource potential.
