Relationship between Phytoplankton and Nutrient Dynamics in the Enclosed Waterbody, Dianchi Lake

Abstract:

An analysis of 170 simples acquired monthly from August 2011 to December 2012 in the closed waterbody suggests that the concentration of algae bloom (Cyanophyta) is dependent on the nutrient dynamics. Without the overlying of nitrate concentrations carried by the external algae bloom, the enclosed waterbody isolated by the flexible enclosure maintains a lower nitrate level. Algae bloom tends to dominate (TN: TP < 12) and to rare (TN: TP>12). Cyanophyta is dominant for the whole year.
