摘要：
Concentration of suspended sediment directly affects the optical properties such as transparency and water color, and aquatic environment as well. This paper selects the Taiwan Strait as study area, establishes inversion mode of suspended sediment by coupling field data with remote sensing reflectance from MODIS data. Monthly-averaged concentrations and seasonal changes of suspended sediment from 2003 to 2012 were calculated and analyzed by the mode. The main results are as follows:(1) remote sensing reflectance at 555nm from MODIS data has high relativity with the field observed turbidity by regression equation of Y =0.8931e(123.93)x in which Y is TSM concentration, X is R(rs)555 and R-2 is 0.6836. (2) Suspended sediment in the Taiwan Strait has obviously spatial and temporal distribution characteristics, that higher concentration of suspended sediment is in coastal water and decreases from shore to sea, and highest concentration happens in winter.
