Abstract

Abstract

In order to understand the spatial distribution characteristics of lake nutrient concentrations and eutrophication states in China, correlation analysis and curve fitting were used to illustrate the relationships between eutrophication-related parameters, such as total nitrogen (TN), total phosphorus (TP), phytoplankton biomass (Chl-a) and trophic level index (TLI), and geographical location parameters, such as longitude, altitude and elevation. The results showed that the concentrations of TN and TP were strongly positively correlated with the longitude and altitude, and negatively correlated with the elevation. However, the variations of TN and TP explained by altitude were only 3.0% and 3.7%, being lower than that explained by longitude and elevation. The concentrations of Chl-a and TLI increased with the longitude and decreased with the elevation, and weakly correlated with the altitude.
