Abstract:The eutrophic status of the Baiyangdian Lake was investigated based on the analysis of water and sediment samples from 2008 and historical data from 1991 to 2007. The water quality of the Fuhe River, which is the major tributary into the lake, was worse than that required by Grade V. The primary production of the plant type lake was closely linked to nutrient limitation in the river water rather than that in the sediments. Under higher nutrient concentrations, the mass ratio of nitrogen to phosphorus (N/P) in the river water fitted the growth of the macrophyte, which was ranged between 14 to 16. Reed dominated in the lake and accelerated the local process of plant type eutrophication. Nitrogen is a limited factor of the eutrophication features in the lake. Thus measures should be carried out to reduce nitrogen pollutants, which mainly originate from industrial wastewater and municipal sewage from Baoding City, in order to ease the eutrophic process of plant type eutrophication in the Baiyangdian Lake.
