Facts and figures about China – the Yellow River Basin

  • The Yellow River is the second longest river in China after the Yangtze River, and the sixth longest in the world. Originating on the Qinhai-Tibetan plateau in western China, it runs for some 5,500 km across the vast North China Plain, traversing nine provinces before draining into the Bo Hai Sea.
  • Its catchment area of 795,000 km2 is home to 110 million people (2000) or about 8.7% of China’s population. (The figures increase to 189 million and 14.9% if the flood plain surrounding the lower reach is included.) In 2000, about 26.4% of the basin was urbanized. Read more
