In this article there was an error found in the statistical description of the trend in Figure 6. The original text read:

‘Fig. 6 presents the annual variations of pH, DO, DOC, TN, TP, CODMn, Tur, and EC in Chinese lakes and reservoirs from 2000 to 2023.From 2000 to 2023, the annual averages of Tur and EC increased significantly with fluctuations (k = 0.0026, p < 0.05 for Tur; k = 0.0001, p < 0.05 for EC) (Fig. 6d and h). By the contrast, pH declined from 7.99 in 2000 to 7.97 in 2023 with a slope of -0.0011 (p < 0.05) (Fig. 6a). While no significant changes were found for DOC, DO, CODMn, TN, TP (p > 0.05) (Fig. 6b, c, e, f and g)’.

And should have read:

‘Fig. 6 presents the annual variations of pH, DO, DOC, TN, TP, CODMn, Tur, and EC in Chinese lakes and reservoirs from 2000 to 2023. From 2000 to 2023, the annual averages of Tur and EC showed significant temporal variations (k = 0.0042, p < 0.05 for Tur; k = −0.0001, p < 0.05 for EC) (Fig. 6d and h). By the contrast, pH declined from 7.99 in 2000 to 7.97 in 2023 with a slope of -0.0015 (p < 0.05) (Fig. 6a). While no significant changes were found for DOC, TN, TP (p > 0.05) (Fig. 6b,f and g)’.
