| In this paper, the existing species and content distribution of nitrogen in sediments from different functional area in Cuihu Lake of Kunming were analyzed for discussing the indicators response relationship between overlying water and interstitial water and sediment, and evaluating the current pollution situation. Results showed that TN content in surface sediment were 564 mg/kg～4 602 mg/kg and increased along the flow direction. TTN content, with SOEF N and SAEF N dominated, varied little. The response relationship existed among dissolved oxygen, oxidation reduction potential, pH, total nitrogen in overlying water, and pH, nitrogen, COD in interstitial water, and the nitrogen species in sediment. |
