Study on the sedimentary systems of compressed shallow-lake basin:taking middle—lower Jurassic in Turpan Depression as an example

Low permeable oil field of large shallow-water lacustrine basin in China is one of the important exploration areas.

The sedimentary tectonic sets belong to closed depression shallow lacustrine basin,and the stratigraphic sequence is similar to that of a craton basin and a gentle slope divergent continental margin.

Total phosphorus (TP), inorganic-phosphorus (IP), organic-phosphorus (OP), Fe/Al-bound phosphorus (Fe/Al-P) and Ca-bound phosphorus (Ca-P) in surface sediment of the seven shallow lakes along the middle-lower reaches of the Yangtze River were measured, using the standard measurement and test(SMT)procedure of phosphorus forms in the freshwater sediments.

The mechanisms of shallow lakes eutrophication were also complex.

Evaluation on temporal and spatial changes of biological integrity for shallow lakes in the middle reach of the Yangtze River;

Adsorption kinetics and isotherms of ammonium onto the 13 sediments taken from shallow lakes in the middle and lower reaches of the Yangtze River were determined, and the effect of physical and chemical properties of the sediments on its ammonium adsorption characteristics was also analyzed.
