a–c MS-DOM, d–f DW-DOM, g–i LW-DOM, and j–l NO-DOM. For each subfigure, the location of a given dot corresponded to the values of its two spectroscopic indices. The solid line was associated with the linear regression line and the shaded area with the 95% confidence interval. Significant relationships were revealed by the two-sided statistical tests via P < 0.05 and P < 0.01.
