英文摘要：

The feasibility of shallow water＇s seafloor type classification with hyperspectral remote sensing based on spectral derivative technique has been investigated.Firstly,the hyperspectral remote sensing reflectance of the shallow water with different seafloor types was simulated with the semi-analytical numerical model.Secondly,the spectral derivative method was applied to the simulated data to analyze the spectral characteristics of the seafloor of different types.Finally,the water pool experiment was carried out to validate the above method.The validating results show that the seafloor covered by sand and seagrass can be detected with the method developed in this study.
