摘    要:利用20 多年的资料,在分析黄河断流发生的频次、历时、河长等现状特点的基础上,从自然地理因素和人类活动因素两个方面综合探讨了黄河断流发生的原因.结果表明:黄河断流是黄河流域人地关系严重失调的综合反映,自然地理因素造成的水量不足是引起黄河断流的客观原因;人类活动的影响,尤其是人类不合理利用黄河水超过了水资源承载能力是引起黄河断流的直接原因

关 键 词:黄河  断流  成因  水资源  承载能力

Abstract:Used the actual data of more than twenty years and based on analyzing the present state of the frequency, lasting and length of the running out of the Yellow River, the article discussed the causes of its running out from the factors of physical geography and human activity: the running out of the Yellow River is a mirror which shows the man land relation has been out of balance in the Yellow River valley. The lack of water caused by the factor of physical geography is the objective cause; the factor of social economy, especially the overuse of water resources which has gone beyond its bearing capacity forms the direct reason.
Keywords:Yellow River  water running out  formation cause  water resources  bearing capacity laser plasma accelerators  plasma wave  electron trapping and acceleration
