Cities and Towns on the North China Plain – September 7th, 200937.1N 119.1E
The green landscape of the North China Plain, in northeast China, is dotted by tan cities and towns. This flat yellow-soil plain is the main area of sorghum, millet, maize, and cotton production in China. At the same time, it is one of the most densely populated regions in the world (see close up of populated areas).
The plain is based on the deposits of the Yellow River (Huang He) and is the largest alluvial plain of eastern Asia. It covers an area of about 409,500 square kilometers (158,000 square miles), most of which is less than 50 metres (160 ft) above sea level.
The plain is bordered on the north by the Yanshan Mountains and on the west by the Taihang Mountains. To the south, it merges into the Yangtze Plain. From northeast to southeast, it fronts the Bohai Sea, the highlands of Shandong Peninsula, and the Yellow Sea. The Yellow River flows through the middle of the plain into the Bohai Sea.
The second close-up focuses on the mouth and delta of the Yellow River and sediments in Laizhou Bay, the southern arm of the Bohai Sea. Some salt evaporation ponds and agricultural areas can be found along the shores of the bay.
