摘要
该文简要介绍了黄河断流的现状、原因及其危害，初步揭示了黄河断流年度双高峰规律与多年逆反规律、利津站断流天数与花园口站月平均流量的关系、利津站全日断流天数与总断流天数的关系等变化规律，并统计分析了利津站最长断流天数、累计断流天数、断流长度、最早断流日期等发展趋势。上述研究为黄河断流预测提供了科学依据，可供有关部门参考。
n this paper, the present situation, the cause and the harm of the absence of flow in the Huanghe River were briefly introduced. The changing regularities of the absence of flow, which include the law of double peaks in a year, the multiyear relationship between the demand and supply of water, the relationship between the days of the absence of flow in Lijin Station and the monthly discharges in Huayuankou Station, the relationship between the number of the whole day absence of flow and the number of the absence of flow in a day or in several hours, were preliminarily revealed. The development tendencies of the absence of flow, that consist of the longest period or accumulative days, the longth and the beginning day of the absence of flow in Lijin Station, were statistically analyzed. The research results provide the scientific basis for the forecast of the absence of flow in the Huanghe River, which are useful to the departments concerned.
