黄河是我国河流中最重要的七大江河之一,黄河之水的开发和利用为沿黄地区的社会文明和经济发展起到了难以估量的巨大作用。但是,近几年来,黄河水资源正受到掠夺性的利用,黄河断流日益频繁。黄河下游从1972～1997年的26年中有20年发生过断流现象。20年中累计断流70余次,合计908天,平均每年断流45天。自1991～1997年,年年发生断流,1997年,黄河断流时间达到了创记录的226天,为北方水资源短缺敲响了警钟。黄河断流给下游沿黄地区工农业生产造成了重大的经济损失。1972～1996年间由于黄河断流使下游灌区
The Yellow River is one of the seven most important rivers in China. The development and utilization of the Yellow River water has played an immeasurable role in social civilization and economic development along the Yellow River. However, in recent years, the Yellow River water resources are being predatory use of the Yellow River cut off more and more frequently. The lower reaches of the Yellow River had a current breaking phenomenon in 20 years from 1972 to 1997 in 26 years. Over the past 20 years, a total of more than 70 breaking-offs occurred, totaling 908 days, with an average of 45 days of breaking-off every year. Since 1991-1997, a cutoff occurred every year. In 1997, the flow-off time of the Yellow River reached a record 226 days, alarming the shortage of water resources in northern China. The Yellow River cutoff caused significant economic losses to the industrial and agricultural production in the areas along the Yellow River downstream. 1972 to 1996 due to the Yellow River off the downstream irrigation area
