The attenuation of ultraviolet radiation in shallow lakes in the middle and lower reaches of Yangtze River;

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.

Plane 2D flow-water quality-sediment pollution couple model in shallow lake;

Fractionation of phosphorus in sediments and its relation with soluble phosphorus contents in shallow lakes located in the middle and lower reaches of Changjiang River, China;

Geochemical　characteristics of phosphorus in sediments of a large shallow lake;

Considering the decrease of water area nowadays, artificial lakes are getting more and more important as a water conservancy which can help improve human environment.

Artificial lakes are important resources in China and the country enjoys the largest number of artificial lakes in the world.

The forms of phosphorus in the surface sediments were extracted and determined sequentially with ethylene dinitrilo tetracetic acid(EDTA) technique in three urban shallow lakes: Lake Xuanwu,Lake Mochou and Lake Daming.
