[Characteristics of Organic Phosphorus Fractions in the Sediments of the Black Water Aggregation in Lake Taihu].

Potential release of phosphorus in lake sediments depends largely on the fractions and distribution of organic phosphorus. MaoDu was chosen as the research area in the west of Lake Taihu. The chemical forms of the surface sediments were investigated by the Ivannoff extraction methods.

[Influence of Submerged Plants on Microbial Community Structure in Sediment of Hongze Lake].

Phospholipid fatty acids (PLFAs) method was applied to analyze the influence of submerged plants on sediment microbial community structure, in order to investigate the changes of sediment microbial community structure for different kinds of the submerged plants in different growth periods. Particularly, Potamogeton crispus L., Potamogeton pectinatus L and the mixed group were chosen as the typical submerged plants in Hongze Lake for investigation in this paper.
