Pollution Characteristics of Nutrients in Sediment at Changtan Reservoir

The pollution characteristics of nutrients in sediment at Changtan Reservoir were analyzed based on the sampling data using organic index, carbon-nitrogen ratio and Pearson correlation coefficients so as to deal with water eutrophication. The nutrients are concentrated on surface sediment and individual areas show high organic pollution. The organic matter is mainly exogenous organic matter and has homologous relevance with total phosphorus.
