Abstract： Total nitrogen (TN) and total phosphorus (TP) are important indicators for assessing eutrophication of lake waters. In this paper, ASD spectroradiometer was used to measure the spectral reflectance of Dianshan Lake. Combined with synchronized water quality sampling and analysis in the laboratory, the correlation between the concentration of TN, TP and spectral measurements was tested. Subsequently, the single band, first-order derivative model and band ratio model was established, respectively. Results show that the first-order derivative model and band ratio model can effectively eliminate the reflectance noise and improve the estimate accuracy. The established model has a reference value to other similar researches for the remote monitoring of TN and TP in inland water bodies.
Keywords： Total nitrogen； total phosphorus；Hyperspectral reflectance；Dianshan Lake
