| 摘 要： | 为在宏观上对黄河中游水沙运动的变化规律从随机过程的角度予以揭示,以黄河中游潼关水文站1952-1998年期间流量超过6 000m3/s的次洪过程中的洪峰流量和相应的沙峰含沙量系列为基础,运用Copula函数方法构建了黄河中游汛期水沙联合分布模型并对其应用进行了探讨.结果表明:在水沙丰枯同步频率中,同丰的频率略大于同枯的...

| Abstract: | To deeply research and disclose change rules of flood and sediment series at the middle reach of the Yellow River from stochastic aspect macroscopically,a joint distribution model of flood and sediment was constructed with Copula function method and then its application was discussed,based on the time series of flood peak flow that over 6 000 m3/s and its corresponding peak sediment concentration during a flood course from 1952 to 1998 of the Tongguan gauge at the middle reach of the Yellow River.The result... |
