Abstract
[Objective] The distribution of suspended sediment in Zhoushan sea area was retrieved by using satellite remote sensing method, and the suitable inversion model was further explored, which will provide reference for remote sensing study of suspended sediment in Zhoushan sea area.[Method] Using field data, remote sensing data and laboratory analysis method, spectral analysis of different water bodies in Zhoushan sea area was carried out, and three kinds of inversion models between water body remote sensing reflectance and suspended sediment concentration were established.[Result] The results showed that the inversion effect of remote sensing parameters model was the best.The second was Logarithmic inversion model.The correlation coefficient was the largest in TM4 band and the smallest in TM3.The linear inversion model was the worst.The correlation coefficient was the largest in TM2 band and the smallest in TM3.[Conclusion] The higher inversion accuracy can be obtained by using the remote sensing parameters model in Zhoushan sea area.
