摘要

The relationship among reed nitrogen (N) uptake, nitrifying and denitrifying bacteria, and N content in the rhizosphere sediment was studied based on field investigation in terrestrial zone (TZ), ecotone zone (EZ), and submerged zone (SZ) of Baiyangdian Lake, the largest natural freshwater body of Northern China. The results showed that the total nitrogen (TN) content in the rhizosphere sediment decreased with increased aboveground reed TN storage, achieving the highest decrease rate of 68.6-78.
