黄河干流长5464 km,流域面积752443 km~2,流经我国西北、华北地区,降水量较少,水资源贫乏。20世纪50,60年代以前,由于人口较少,经济处于低水平运转的时代,水资源尚能满足沿黄地区经济发展和生活的需要。20世纪70年代以来,随着经济的迅速发展,工农业及生活用水量急剧增加,水的供需矛盾充分暴露出来,下游断流日趋严重,成为制约沿黄流域经济发展的重大障碍。黄河水资源问题不但给中、下游的经
The Yellow River main stream is 5464 km long and the basin area is 752443 km ~ 2. It flows through the northwestern and northern regions of China with less precipitation and poor water resources. Before the 1950s and 1960s, due to the small population and the economy being at a low level, water resources could still meet the needs of economic development and living in the Yellow River areas.
