自１９８７年起，黄河下游几乎年年断流，且断流时间不断提前，历时不断增加．断流使下游工农业生产、油田开发、城乡人民生活生态环境等很多方面受到严重影响，经济损失巨大．本文分析断流形成的原因认为一是天然径流不足，二是人为影响防止黄河断流，重点在于解决下游枯水灌溉季节来水少，用水多的矛盾，主要对策有：增加来水量，减少用水量，调整用水时间，加强水环境保护．
Since 1987, the lower reaches of the Yellow River have cut off year after year, with a continuous flow-off time and an increasing duration. The drying up severely affected many aspects of downstream industrial and agricultural production, oilfield development, urban and rural people’s living environment, and caused huge economic losses. This paper analyzes the reasons for the formation of broken flow that one is the lack of natural runoff, the second is human-induced prevent the Yellow River cut-off, the focus is to solve the lower dry season irrigation less water, water and more contradictions, the main countermeasures are: to increase the amount of water to reduce Water consumption, adjust water use time, strengthen water environment protection.
