摘要

分析了黄河源头断流的成因

认为黄河源区以湖泊、沼泽为主的地貌特征

稀少的降水

年径流的丰、枯悬殊

贫乏的水资源

湖面的蒸发和冬季寒冷的气候及年径流的周期性变化都是造成断流的原因。造成断流的主要根源是源区水资源的贫乏和湖面的蒸发。黄河源头断流有一定的周期性

是以自然因素为主影响的结果

不应把黄河源头的断流现象看成是黄河源区生态环境恶化的象征。

Abstract

The causes of the Yellow river flow-stopping can be at tributed to the characteristics of lake and marsh as main landforms

rare precipi tation

disparity in annual runoff amount between dry and moist year

water resources shortage

lake surface evaporation

the cold climate in winter

and the periodic variation of annual runoff amount in the source area. Among which

shortages of water resource and lake surface evaporation are the major reasons. The flow-stopping showed periodicity analysing from the hydro-data. It was the results of natural factors

so the flow-stopping now should not be considered as emblem of eco-envi ronment worsening.
