Abstract

To understand the pollution characteristics of nitrogen and phosphorus in surface sediment of the Eastern byas of Lake Taihu (Gonghu Bay, Guangfu Bay and Yuyang Bay) and its relationship with the growth of aquatic macrophytes, contents of total nitrogen (TN), total phosphorus (TP) and total organic carbon (TOC) of surface sediments were determined based on the investigation of surface sediment in eastern bays of Lake Taihu with aquatic macrophytes. The effects of aquatic macrophytes on pollution characteristics of TN, TP and TOC in surface sediments were analyzed, and pollution assessment for surface sediments was made. The results showed that the contents of TN, TP and TOC in growing area of aquatic macrophytes were significantly lower than that of the contrasted open water area, and the growth of aquatic plants has significant effect on TN, TP and TOC contents in surface sediments. Correlation analysis showed that TOC and TN were significantly correlated (R²=0.832 8), but with less significant correlation to TP (R²=0.166 5), reflecting TOC could become an important source of nitrogen in the deposition process of lake sediments, but less impact on the phosphorus. By evaluation pollution situation with organic index and organic nitrogen, the average organic index of Gonghu Bay, Guangfu Bay and Yuyang Bay were 0.142 7, 0.228 6, and 0.208 6, respectively. However, the average number of organic nitrogen was on the Ⅲ and Ⅳ level, which showed that nitrogen pollution of sediment is more serious. The investigation suggested that the control and reduction of nitrogen in surface sediment of the contrasted open water area are of important significance to the prevention and control of lake eutrophication.
