摘要：
Effects of nitrogen (N), phosphorus (P) and their ratios (N/P ratios) on the eutrophication in the Baiyangdian Lake, a macrophyte-dominated lake, were investigated based on long-term observation of water quality from 1991 to 2008. Nutrient inputs via the Fuhe River, the largest tributary, accelerated eutrophic process of the lake. The concentrations of total N and total P ascended annually and ranged in 10.26-36.60 mg/L and 0.89-3.07 mg/L, respectively. N/P ratios in the river varied from 10 to 17, which fitted the growth of macrophyte and made the reed dominated in the lake. The results indicated that N is the restricted factor of eutrophication and thus N removal from the river is essential to relieve eutrophication in the lake. In the case of high nutrient concentration. NIP ratios can be used to indicate the types of lake eutrophication.
