Nitrogen pollution of groundwater in a typical catchment was investigated in order to understand the nitrogen contribution from groundwater to the serious eutrophication in Dianchi lake. The characteristics and patterns of temporal and spatial distribution of nitrogen in groundwater were obtained for the typical river catchment in Dianchi watershed. Additionally, four factors controlling variation in the nitrogen concentrations in groundwater, such as precipitation and N fertilizer applications, were indentified.
