摘要： A method for discriminating vertical distribution models of organic carbons is provided, the method includes: obtaining a concentration of organic carbons in a surface layer of the ocean water area, depths of water of the ocean water area and depths of mixed layers of the ocean water area; determining different vertical distribution models of organic carbons in the ocean water area according to the concentration of the organic carbons in the surface layer and the depths of water of the ocean water area; calculating ratios of the depths of water of the ocean water area to the depths of the mixed layers of the ocean water area; and discriminating the vertical distribution models according to the ratios. According to this method, the accuracy of estimation of the stock of organic carbons in the ocean water area can be improved greatly.
