The eco-environmental conditions of the Yangtze River are very complicated. From 1987 to 1990, a comprehensive geochemical investigation on the aquatic environmment in this area was conducted. Natural contents and background values of 31 elements
Results and discussion of a stratigraphic survey made of a 21-m-profile of floodplain sediments on the watershed between the Chang Jiang (Yangtze River) and Huang He (Yellow River) at 2500 m asl.: distribution of the floodplain deposits
Since the anabranched river pattern is the most typical one in the middle and lower reaches of the Yangtze River (Changjiang) as well as in many other rivers in China, a systematic study on the formation cause of the anabranched river pattern has
