| 摘 要： | 本文以泾、洛、渭三河流干流在陕西境内的主要控制断面为例,分析了１４个时段枯水流量的概率分布特征,选定了理论分布线型,揭示了各枯水序列的时段平均流量均值、变差系数和偏态系数的变化规律,建立了推求不同频率不同时段的枯水流量的经验公式。绘制了相应的关系曲线,应用十分方便。

| Abstract: | Taking the main control sections of the Jing ,Luo and Wei Rivers within Shanxi as examples,this paper has analysed the characteristics of the probability distribution of the low flows in 14 periods; selected the types of the theoretic distribution lines; revealed the change laws of the average values of the period mean flow of various low flow series; the change laws of the variation coefficient ,and the change laws of the deviation coefficient; established the empirical formulae for deriving the low flows with different frequencies and in different periods;and drawn the corresponding relation curves. All the results are very convenient for application. |
