Organic matter content of typical soil in coastal zone was retrieved by using soil spectral reflectance.Spectral reflectance characteristics of 97 coastal soil samples of Laizhou Bay were analyzed.The spectral curves were divided into four regions.In each region,typical characteristic parameters were picked up to make a correlation with soil organic matter content.Finally,regression analysis model was made with the deflection in the range of 458～587.1 nm as independent variable.The model was evaluated by Root-Mean-Square Error（RMSE） and RPD（the ratio between the stand deviation of the reference method against that of the RMSE）.RMSE and RPD of the logarithm function model were 0.39 and 2.5 respectively,which demonstrated that the regression analysis prediction model can be applied to retrieve coastal organic matter content with good accuracy and stability.
