This paper studied the spatial distribution of small fishes in a shallow macrophytic lake, Niushan Lake in spring 2003, and its relations with habitat heterogeneity.

Large and medium shallow weed-type lakes account for the major proportion in the eastern plain lake zone in the middle and lower reaches of the Changjiang River.

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;

Evaluation on utilizating function damage for grass type lakes in arid area;

Based on the grass type lakes wetland resources's character,the economics theory and method is applied in the paper on the base of the investigation and experiment to analyses the asset value type of the wetland resources and to evaluate the values in Wuliangsuhai lake wetland.
