The excessive and unbalanced use of chemical fertilizers, domestic sewage discharges, manure applications to land, soil nitrogen (soil N), and precipitation contribute to N accumulation in aquatic systems, where high concentrations of N in surface water can cause eutrophication. Because high concentrationsofN in water pose a seriousthreat tohumans,it isimportant to control the N in aquatic ecosystems. It is useful to identify N sources in the environment so that the causes of increased N fluxes in aquatic ecosystems can be determined and N inputs can be efficiently reduced. Additionally, if the sources can be identified, management practicesrelatedtomaintainingwater quality in many at-risk watersheds canbeimproved. 主要科研项目/Mainresearchprojects： 1. 城市湖泊环境地下水氮污染机制及其对富营养化调控的基础研究—以杭州西 湖为例 国家自然科学基金, Research on the nitrogen pollution mechanism in groundwater and the theory about the influence of groundwater on eutrophication control in the West Lake watershed, The financial support from the National Natural Science Foundation of China. 2. 氮同位素研究农业污染物输入对地下水系统的影响, 国家自然科学基金 Using nitrogen isotope to indicate effect of agricultural pollutions on groundwater, The financial support from the National Natural Science Foundation of China. 代表性论文/
